IWS 2013 General Chair’s
WelcomeThe International Wireless Symposium (IWS) is a new microwave conference sponsored by the IEEE
Microwave Theory and Techniques Society debuting in 2013. Don’t miss this first time meeting.
It will be an international event that will be held annually in China; the first will be held in Beijing,
China. The focus is “everything that is wireless”, including phones, Bluetooth, Zigbee, data, and amyriad of hardware, as well as regulatory and provider issues within the wireless community. Patterned
after the very famous MTT-S International Microwave Symposium (IMS), the IWS will have a technicalconference and a commercial exhibition. Because the market place for wireless technology, devices,and service is immense, the IWS will grow to be similar to the IMS. This year we will have over 160
papers presented in multiple parallel tracks, with over a hundred industrial and other exhibitors. The
papers presented at IWS will be archived in IEEE Xplore. IWS will rotate between several locationsin China, but will be an international event with participants from all over the world. The exhibition
will include manufacturers and service providers from worldwide, with marketing happening in both
directions: both into, and out from China. The IWS is intended to attract attendees and exhibitorsfrom all parts of the wireless community, and will become a major global wireless event!
Let’s look forward to Xi’an in 2014.

Welcome to IWS 2013 and Beijing,China!
Beijing, the capital of the People’s Republic of China, is the center of the nation’s politics, culture and international
exchanges and a moden metropolis full of vitality. The world’s earliest record of Beijing came from the travel notes by
Marco Polo, the young Italian traveler in the 13th century. His description of people’s civilized and well to do life in Beijing
and his admiration for the beauty of the city has for hundreds of years attracted the reverie of numerous people about thisancient capital of civilization in the East.
Beijing）literally means “the northen capital”. The city construction of Beijing has a history of over 800 years dated back to
the year 1153 AD when the Jin Dynasty (1115-1234) built Beijing as its capital later named “Zhongdu”. Mongol armies
seized Zhongdu in 1215. Kublai Khan rebuilt the city and gave it the Chinese (Han) name of Dadu or Great Capital as
capital city called “Dadu” in Yuan Dynasty (1271 – 1368).
On 2 August 1368, Ming troops conquered Dadu and renamed it Beiping (Northern Peace). Zhu Yuanzhang was thefounding emperor of the Ming Dynasty (1368-1644). When the Manchus founded the Qing Dynasty in 1644, they began
to build suburban gardens, the most famous of which was Yuanmingyuan.
Qing Dynasty (1644 - 1911) left the city wall and palaces built in Ming Dynasty almost intact. So Beijing’s city plan was firstlaid out in the Yuan Dynasty (1271 - 1368). Yet only after massive reconstruction during the Ming and Qing (1644-1911),
did the city come as an architectural masterpiece as the capital of the Chinese empire.
Nanjing was officially made the capital of the Republic of China in 1928. Beijing was renamed Beiping, meaning “northern
peace” or “north pacified”. During the Anti-Japanese War, Beiping fell to Japan on 29 July 1937.
On 1 October 1949, the Communist Party of China, under the leadership of Mao Zedong, announced in Tiananmen thefounding of the People’s Republic of China and renamed the city back to Beijing. This date became China’s national day.

Transportation
Beijing Capital International Airport:
Beijing Capital International Airport is located in northeast of Beijing, capital of People’s Republic of China. Over 70
domestic and foreign airline companies are participating in the operational business, including over 10 domestic
companies and about 60 foreign companies.

Airport E-mail: service@bcia.com.cn
Airport Website: http://en.bcia.com.cn/
Time Zone: GMT + 8
Address: Beijing Capital International Airport, Airport Road, Chaoyang District, Beijing 100621, China
Location: The airport is located 30km northeast of Beijing city center.
Airport code: PEK; Country Code: 86
Number of Terminal: Beijing Capital International Airport has three terminals (T1, T2 and T3) in operation.
When arriving at the airport, keep away from taxi drivers who approach you in the terminal or outside the terminal as they
will ask for much more than the actual price. These are not approved taxi vendors.
Just follow the taxi sign and there is a taxi stand outside the each terminal. Drivers should use their meter; make sure thatthe driver puts down the flag. Beijing capital airport is located about 20km to the northeast of Beijing city center. Taxi
charges from Terminal 3 at Beijing capital international airport to Beijing downtown: about CNY 130 inclusive of both atoll gate fee (CNY 10) and a fuel surcharge (CNY3). Taxi charges from Terminal 2 at Beijing capital international airport toBeijing downtown: about CNY 120 inclusive of a fuel surcharge (CNY3).
If you take a taxi to Beijing airport from downtown Beijing at rush hour (morning and afternoon), it is best to call a taxi
several hours in advance of your departure time. Although the Metro is often quicker during peak hours, a taxi is much
more convenient.
Beijing legitimate taxi license plates will be for the “Beijing B” otherwise it is a black taxi! After paying a legal taxi, you will
get a legal computerized receipt in which you can find the taxi company’s phone number while a black driver only offers
you a hand-written receipt with which you will never find him! A black driver would charge you RMB 400 - RMB 500 for
the airport downtown drive.
Beijing Capital Airport has three terminals - T1, T2 and T3. Each Terminal has its own airport taxi stand.

Additional Taxi Information:
There are approx. 70,000 taxis going in and around Beijing. Basically the taxi volume in Beijing could meet the increasingtaxi market demand. But at peak hours, people find it extremely hard to hail a taxi on the streets.
Most of the taxi drivers can speak little English, you are advised to keep the name of your hotel written in Chinese or you
may ask your hotel staff to write it down for you. So you are able to show it to a driver.
All legitimate taxis in Beijing use meters, so just get in the taxi and pay the fare when you get out. To avoid possible
dispute, you are advised to take fapiao (receipts) which will be printed automatically for you.

4Daytime: 0500 - 2300
· RMB 10 just for getting in for 3km· RMB 2 charged for additional 1km after 3km· RMb 3 charged for additional 1km after 15km
Midnight: 2300 – 0500
· RMB 11 just for getting in for 3km· RMB 2.4 charged for additional 1km beyond 3km· RMb 3.4 charged for additional 1km after 15km
· Waiting in a traffic jam or for the lights to turn green, it is charged as 1 kilometer per 5 minutes.
Very important notices:
1. Three yuan (CNY3) surcharge will be added beyond 3km to balance the oil hike according to the policy of the local government.
2. Taxi charges from Terminal 3 at Beijing capital international airport to Beijing downtown: about CNY 130 inclusive ofboth a toll gate fee (CNY 10) and a fuel surcharge (CNY3).
Taxi charges from Terminal 2 at Beijing capital international airport to Beijing downtown: about CNY 120 inclusive of afuel surcharge (CNY3).
Note:1) The Beijing Airport Expressway for Terminal 2 is free of charge into the city, but retains the CNY 5 fare toward T2 atBeijing capital airport.
2) The Beijing Airport Expressway for Terminal 3 is CNY 10 toll fee into the city, also CNY 10 fare toward T3 at Beijing
capital airport.
Reminders:1) Official taxis have a taxi sign on the roof, and on the dashboard on the passenger side is a placard with the drivers
registration number. If this placard is missing then avoid it. At your destination, you should requrst a fappiao (a receipt,
which is generated by the meter). If the meter isn’t working, you can refuse to pay, and if the driver threatens to callthe police, encourage him to do so. At this point he will write a hand-written fappiao, but make sure he (or you) writes
down the car registration and the driver registration before paying your money for the taxi.
2) Please keep the address card from your hotel or written by your hotel staff in Chinese to show the taxi driver. A hotel
card with the Hotel’s name in Chinese for your return trip. So always carry a card from the hotel in the event you getlost in the city. Show the card to the driver and ask him to bring you there. Most of the drivers are not able to speak in
English.
3) You can also charter a taxi (as a private your own car ) for day trips to the Great Wall ( which is around 1.5 hour drivefrom city) or just to transfer you around various locations like Forbidden City, Summer Palace, Temple of Heaven,
Panjiayuan, Wangfujinging, etc. As long as it is within the city, most drivers are more than willing to let you charter their
car for the day. A typical taxi will cost around RMB450 to RMB600 for an 8-hour day rental with driver. Each car canhold 4 comfortably. If you are sharing the car among 4, that is less than US$20 for a day.
4) Travelling around Beijing by taxi is quite easy. However, when it rains, it becomes a totally different situation. Keepin mind if you have a plane or train to catch, especially if you have an unchangeable ticket! Firstly, cabs can be very
difficult to find in the rain. Secondly, many taxis will simply refuse to take on longer journeys, especially to the airport
and they also will refuse to go anywhere if it involves driving on the 3rd Ring Road which is jammed completely in the
rain! So check the weather report and it is better to plan to get to the station or airport three hours before check-intime if your ticket is unchangeable.
5) The bridge and road tolls will be paid by passengers. For a journey that takes longer than 10 kilo or running after 23:00,
the fares will be charged at 50% more.

Beijing, China offers great opportunity
for you and your family to sightsee
while at IWS 2013!
A Brief Overview of Beijing:
Beijing is the capital of the People’s Republic of China. The city has a long history that can be traced back to as early as
1045 B.C. The long history has left a variety of famous historical sites which possess great aesthetic and cultural value. The
Great Wall, a huge project with construction started more than 2,000 years ago, meanders through mountains and valleys.
The Forbidden City, the largest ancient architectural complex extant today, is a splendid crystallization of ancient Chinesearchitectural arts. The Summer Palace, an ancient royal garden with numerous styles of ancient buildings and gardens, is avirtual museum of traditional Chinese gardening.

Weather in April:
Please visit: http://www.weather.com.cn/en/weather/101010100.shtml

Tours:
1. The Forbidden City and Tian’an Men Square
The Forbidden City was the Chinese Imperial palace from the mid-Ming Dynasty to the end of the Qing Dynasty. It is
located in the middle of Beijing, China. It now houses the Palace Museum. The complex consists of 800 buildings with
8,886 rooms. It covers 720,000 square meters. The Forbidden City was declared a World Heritage Site in 1987 as the“Imperial Palace of the Ming and Qing Dynasties,” and is listed by UNESCO as the largest collection of preserved ancientwooden structures in the world.
The Tian’an Men Square is the geographical center of Beijing City. It is the largest city square in the world, occupying an
area of 440,000 square meters (about 109 acres), and able to accommodate 1,000,000 people at one time. The squarecontains splendid and beautiful flowers and the red national flag flutters in the wind over it all. The raising of the national
flag is something which should not be missed by visitors to Tian’an Men Square.
2. The Great Wall and Ming Tombs
The Great Wall of China is an ancient Chinese fortification constructed over 300 years, from the end of the 14th century
until the beginning of the 17th century, during the Ming Dynasty, in order to protect China from raids by the Mongols andTurkic tribes. It was

10preceded by several walls starting in the 3rd century BC against the raids of nomadic tribes coming from areas now inmodern day Mongolia and Manchuria. The Wall stretches over a formidable 6,350 km (3,946 miles), from Shanhai Pass on
the Bohai Gulf in the east, at the limit between China proper and Manchuria, to Lop Nur in the southeastern portion of
Xinjiang Uygur Autonomous Region.
The Ming Tombs lie in Changping County, about 50 kilometers (31 miles) northwest of the urban area of Beijing. It is
actually a tomb cluster of the Ming Dynasty (1368-1644), including thirteen emperor’s mausoleums, seven tombs forconcubines, and one grave for eunuchs. This cemetery is world famous because of the thirteen emperors buried here.
Sitting at the foot of Mt. Yan and occupying an area of more than 120 square kilometers (29,653 acres), The tombs are
extremely spectacular. It was placed on the World Heritage List in 2003.

3. The Summer Palace
The Summer Palace, Yiheyuan in Chinese, is the most celebrated imperial garden in China. The garden came into existence
early in the 1750’s and had once been a summer resort for the emperors. It is acclaimed as a museum of gardens in China,
for a visit to this garden bestow on sightseers a glimpse of representative scenes all over China.
4. The Lama Temple and Temple of Heaven
The Lama Temple is the largest and best-preserved lamasery in Beijing. It was built in 1694 during the Qing Dynasty(1644-1911) as the residence of the Emperor Yongzheng (the third emperor of the Qing Dynasty) before he ascended thethrone. In the year 1744, the residence was completely converted into a lamasery. This resplendent architectural complex
is endowed with the style of an imperial palace, making it distinctive from others. It occupies an area of 66,400 square
meters (16 acres) and is described as a mini-palace with yellow glazed tiles on the roof and red walls circling the group ofbuildings.
The Temple of Heaven (also Tiantan Park) is the grandest cult architecture complex in the world and a masterpiece of theChinese people created in ancient times. It covers 2,700,000 square meters (667 acres). The temple was constructed in 1420
during the Ming Dynasty (1368-1644), and was enlarged during the Qing Dynasty (1644-1911). Emperors of the two dynasties
used to worship heaven and pray for rich harvests, as the feudal emperors thought they were the son of the heaven.

Program Chair’s
On behalf of the Technical Program Committee of the inaugural IEEE International Wireless Symposium, we welcome you
to Beijing and exciting IWS 2013 technical program.
IWS 2013 technical program features core technologies for the next generation wireless networks and systems bypresenting up-to-the-last minute achievements in the areas of, but not limited to, Short-Range, Broadband, and Green
Wireless Systems & Standards, Modulation, Coding & Signal Processing, Wireless Energy Transmission & Harvesting,
Smart Grid, as well as their enabling RF, Microwave, Millimeter-wave & THz Technologies including Front-End Electronics,
Antennas, Signal Generation & Power Amplification, Transceiver Techniques, Active/Passive Electronics & Components, andAntennas. The Technical Program Committee received 355 papers including 20 invited from 35 countries (5 continents)
worldwide, indicating the vitality of this new conference and promise for further future growth. Based on our TPC
recommendation, we will present 161 regular and invited papers – corresponding to an overall acceptance rate of 45%– scheduled for 24 podium sessions and 2 poster sessions over 3 days covering the complete range of IWS technicalinterests. Don’t miss our daily Focus Sessions featuring invited talks on Technologies For Advanced Wireless Devices,
Wireless Data and Power Transceivers For Biomedical Applications, Emerging Wireless Devices And Design Techniques,
Cognitive Radio Communications and Networks, and RF Nanotechnologies for Next Generation Wireless Communications.
In addition to our technical podium/poster sessions, we also offer 12 workshops, 3 short courses, and 2 panel sessions, forin-depth discussions on device, circuit, and system aspects of wireless technology.
We would like to thank our 160 TPC members and subcommittee chairs for their hard work and invaluable time to review
and select the papers. Without their selfless efforts it would have been impossible to form such a high quality technicalprogram. We also would like to thank all the authors for submitting their papers to the symposium, and we regret if wewere unable to accommodate many of the quality contributions this year. We hope that you will consider submitting yourwork to the subsequent IWS, scheduled for April 2014 in Xi’an.
Enjoy Beijing, and we look forward to seeing you all again in Xi’an.

In-line Eighth-Order Pseudoelliptic Filter using Dielectric Resonator Quadruplets Implemented
using Bypassing Evanescent Modes
S. Bastioli, R. V. Snyder, RS Microwave Company Inc, Butler, United States
A new quadruple-resonator configuration for the design of in-line pseudoelliptic dielectric resonator filters is
proposed in this paper. The proposed configuration uses waveguide evanescent modes bypassing the resonators to generate cross coupling between the non-adjacent ring-shaped TE01δ mode resonators. Specifically,
fourth-order filtering functions with a pair of symmetric transmission zeros can be generated by this configuration. An in-line eighth-order C-band filter comprising a couple of cascaded quadruple-resonator configurations
for the generation of four symmetric transmission zeros is presented. The experimental results of a manufactured prototype validates the feasibility of the proposed filter structure.

Power Consumption Analysis of Bluetooth Low Energy, ZigBee, and ANT Sensor Nodes in a Cyclic Sleep
Scenario
A. Dementyev1,2, S. Hodges2, S. Taylor2, J. R. Smith1, 1University of Washington, Seattle, United States, 2Microsoft Research,
Cambridge , United Kingdom
This paper is intended to guide developers of wireless systems who are puzzled by the vast number of radio configuration
parameters and options. We provide experimental data comparing power consumption of Bluetooth Low Energy (BLE),
ZigBee and ANT protocols for a cyclic sleep scenario, in which a short-range and low-power wireless sensor node periodically sends a data packet to a remote ‘hub’ with intervening sleep intervals. Devices such as wearable health monitors
often use this scenario to interface with a mobile phone-based hub. For all measured sleep intervals BLE achieved lower
power consumption (10.1 uA, at 120 s interval), compared with ZigBee (15.7 uA), and ANT (28.2 uA). Power consumption
differences can be attributed to the time taken for a node to connect to the hub after waking up and the use of sleep
between individual RF packets. For the three protocols we determined a sleep interval at which the trade-off between
power consumption and data rate is optimized

Y. Ma, E. C. Kan, Cornell University, Ithaca, United States
We propose a multi-path interference reduction method of continuous wave (CW) passive RFID for indoor ranging applications by adopting nonlinear transmission line (NLTL) tags. Because the power and phase information are contained
within the second harmonic (SH) rather than the fundamental frequency, interference and phase errors caused by directreflections of interrogating signal can be greatly reduced. We present both theoretical predictions and simulations, followed by experimental results to verify the effectiveness of the proposed approach.

Efficient Optimal Power Allocation for MIMO MAC in Cognitive Radio Networks
P. He1, L. Zhao1, J. Lu2, 1Ryerson University, Toronto, Canada, 2Tsinghua University, Beijing, China
This paper considers a Cognitive Radio network, in which the unlicensed Secondary Users are allowed to concurrently
access the spectrum allocated to the licensed Primary Users provided that their interference to the primary users satisfies
certain constraints. Under ensuring the quality of service of the PUs, the precious spectrum resource can be utilized by
maximizing the sum-rate and optimizing power allocation of the SUs. On the other hand, the multiple-antenna mobile
user case needs further investigating for the problem mentioned above. Thus, we simply term this setting as MIMO multiple access channels in the CR Networks. To effectively and efficiently optimize the power allocation of the SUs, a tightpair of upper and lower bounds of the optimal Lagrange multiplier is proposed. Furthermore, a novel water-filling is
proposed for the inner loop computation of the proposed problem. It is shown that the new water-filling can obtain theexact solution with a few finite computations.

Y. Wang, W. Lu, H. Zhu, Nanjing University of Posts & Telecommunications, Nanjing, China
Measurements for frequency domain characterization of indoor short range wireless channel with persons centered at
2.6 GHz Long Term Evolution (LTE) band were conducted by using a vector network analyzer. Based on the measurement
data, the impulse response of the channel is obtained by using inverse Fourier transformation. The analysis results showthat the optimized-fit distribution of small-scale magnitude statistics yields to Nakagami-m distribution, and the optimized-fit distribution for number of multipaths statistics is t-location-scale distribution.

This paper reports a compact dual-passband filter by using multilayer liquid crystal polymer technology. The
investigated filter consists of two resonators on the middle metal layer, which can be independently designed
for the two passbands. To achieve a compact size, the resonator for the upper passband is embedded in theresonator for the lower passband. Cross coupling between input and output ports is adopted in the design
to improve the selectivity of the reported filter. Experiment is carried on to verify the predicted results and awell agreement is obtained. The proposed filter has a compact size and can be easily designed with flexible

D. Wang1, Y. Chang1, W. Che1, Y. Chow2,1, 1Nanjing University of Science and Technology , Nanjing, China, 2University of Waterloo, Waterloo, Canada
Based on a proposed approach, a novel low-profile tri-band frequency selective surface (FSS) is presented. The
FSS consists of a two-dimensional periodic array of metallic square loops and complementary apertures arranged periodically, centered within a wire grid and an aperture grid respectively. A very thin substrate, with theoverall thickness of 0.007 λ1, 0.013 λ2 or 0.0195 λ3, where λ1, λ2 and λ3 are the free space wavelengths of thethree bands respectively, supports this whole structure. The proposed FSS provides: 1) three passbands separated by transmission zeros, 2) advantage of low profile, and 3) insensitivity to incident angles and polarizations.
An equivalent circuit model is given for predicting and analyzing the frequency characteristics of this structure.
Furthermore, a tri-band FSS with uniform band spacing is fabricated and measured. Good agreement between
the simulated and measured results is obtained.

and a 3l/4 transmission line are used to transmit signal from Port 1 to Port 2. Two l/4 shorted lines are introduced to
improve the passband transmission characteristic. Two transmission zeros and good harmonic suppression can beachieved in the whole band.

H. Kassiri Bidhendi1,2, M. Deen2, 1University of Toronto, Toronto, Canada, 2McMaster University, Hamilton, Canada
A low-power, highly linear CMOS double-balanced mixer for UWB applications is presented. The mixer is designed based on well-known folded architecture and also benefits from DC isolation of RF (Radio Frequency)
and LO (Local Oscillator) stages. Stacked NMOS-PMOS gm-boosting topology is used in the design of RF stage.
To achieve very low power consumption, this stage is biased in sub-threshold region. Also an ultra-wideband
active balun is designed and fabricated to generate differential inputs. The balun is separately characterized
and its performance is reported separately as well as together with mixer. The design is implemented using 130
nm CMOS process and is operational from 3.1-10.6 GHz. The measured maximum conversion gain shows highvalues of 14.9 dB for mixer core. Also, the measured double sideband noise figure has a minimum value of 7.8
dB for mixer core and 12.9 when balun is added. In addition, input (RF and LO) port matching is achieved withreflection of more than 10dB.

+14 dB Improvement in the IIP3 of a CMOS Active Mixer Through Distortion Cancellation
M. Wang, S. He, C. Saavedra, Queen’s University, Kingston, Canada
The derivative superposition (DS) technique is used to cancel the third-order intermodulation distortion(IMD) produced in a downconverter mixer. By providing separate bias currents to the mixer core and the distortion-cancelling circuitry, the IMD is reduced but the conversion gain remains nearly the same in the distortion-cancelling mixer compared to the baseline mixer without linearization. Measurements show that the
distortion-cancelling mixer has an IIP$_3$ that is 14 dB above the IIP3 of the baseline mixer while the conversion gain drops by only -0.7 dB. The distortion-cancelling mixer only needs an additional 2.4 mW of dc power
relative to the baseline mixer’s power draw. The test chip was fabricated in a standard 130 nm CMOS process andoccupies an active area of 0.1 mm2.

T. Gillenwater1, F. Schindler2, 1RFMD, Greensboro, United States, 2RFMD, Billerica, United States
The mobile handset is well established as a business and consumer device, expanding beyond the foundation built on earlier mobile handset technology. The functions and capabilities of the handset are continually
evolving. Handset providers, application developers and users are putting ever greater demands on handsets
which simultaneously strain limited battery power and require higher data transfer. This results in ever morechallenging requirements on the RF front-end of the handset. At the same time there are cost pressures that
require functions to be provided ever more economically. This paper discussed these trends, the implications infront-end architecture, and some of the advanced implementations that address these dynamics.

Advanced Linear PA Architectures for Handset Applications
B. Kim, Pohang University of Science and Technology, Pohang, Republic of Korea
The handset PAs for advanced system, such as 4G and beyond, should handle signals with high PAPR. For amplification of the signals, efficiency of the PAs is degraded significantly due to the operation at a low power region.
For the system application point, the PAs are required to have a multimode and multiband capability, also. These
stringent requirements ask advanced design architectures of the PAs. These architectures are based on a highly
efficient amplifier and try to maintain the high efficiency at a low power level. The representative architectures
are ET technique, Doherty amplifier, class-S amplifier, LINC and some digital PAs.

A Passive Quadrature Generation Scheme for Integrated RF Systems
J. Park, H. Wang, Georgia Institute of Technology, Atlanta, United States
Abstract: This paper proposes a transformer-based quadrature generation scheme, which converts the RF input
signal into the quadrature output signals. By employing multi-turn coil structure and new capacitive phasecompensation on the through and coupling ports, the presented scheme can be implemented in a very compact
footprint with high quality quadrature signal, making it feasible for cellular applications. Compared to conventional quadrature generation methods, this scheme provides low-loss, wide bandwidth, and most importantly robustness to process variations. As a proof-of-concept design example, we demonstrate a 2 GHz 8-turntransformer-based quadrature generation block implemented in a standard 65 nm CMOS process. The whole
design only occupies 280 μm by 280 μm chip area. The detailed design parameters and the simulation results
including quadrature balance, passive loss, input matching, and Monte-Carlo results under process variations
are all presented.

Differential Bandpass Filter with High Common-Mode Rejection Ratio inside the Differential-Mode Passband using Controllable Common-Mode Transmission ZeroJ. Shi, J. Chen, H. Tang, L. Zhou, Nantong University, Nan Tong, China
Controllable common-mode transmission zero is proposed to improve the common-mode rejection ratio(CMRR) inside the differential-mode passband of differential bandpass filters. With the controllability of thecommon-mode transmission zero, the common-mode transmission zero can be moved into the frequency rangeof the differential-mode passband, and then the CMRR inside the differential-mode passband can be greatly
improved. Two two-order filters using different resonators are designed to demonstrate the existence and controllability of the common-mode transmission zero. A four-order filter with two resistor-loaded stepped-impedance resonators (SIRs) and two resistor-loaded uniform impedance resonators (UIRs) are designed to getgood selectivity of differential-mode passband and wide-band common-mode suppression besides the high
CMRR inside the differential-mode passband. The design methodology and experimental results of the proposed filters are presented.

Two stubs are attached at the center of the first and the fourthresonators respectively to obtain an additional passband, resulting in a dual-band filtering feature.

A class of microstrip triple-mode bandpass filters (BPFs) using a patch-loaded cross resonator are modeled, designed and tested in this paper. First, a symmetrical equivalent LC network is developed for a symmetrical patch
structure. The values of all the inductors and the capacitors are extracted by applying the even-odd mode analysis. Then, three 1-port networks are developed to analyze the resonant conditions of the corresponding modes.

A compact, dual band, circularly polarized (CP) multilayered stacked microstrip antenna over reactive impedance
surface (RIS) is studied and presented in this paper. The CP radiation with compact antenna size is achieved byplacing two asymmetric slit square patch (ASSP) and cross-shaped slotted square patch (CSSP) radiators overthe RIS. Dual band is achieved by using the CSSP and ASSP stacked patches placed over RIS, fed by a coaxial
probe at proper location to generate CP radiation. The measured results of the proposed antenna are 1.61%(1.235-1.255 GHz): L2 band and 1.25% (1.585-1.605 GHz): L1 band for 3-dB axial ratio bandwidth (BW), 2.00%(1.235-1.260 GHz): L2 band and 1.57% (1.580-1.605 GHz): L1 band for 10-dB impedance BW, and 2.68 dBic: L2band and 4.46 dBic: L1 band for gain at the boresight for compact antenna overall volume of 0.26λo × 0.26λo

Hong Kong
A new kind of Yagi array of microstrip quarter-wave patch antennas is presented. The antenna array has a low
profile and provides a high gain and a vertical polarization at endfire. Compared with previous Yagi array of

A Compact Fully Differential Doherty Power Amplifier
S. Chen, Q. Xue, City University of Hong Kong, Kowloon, Hong Kong
In this paper, a compact triple-transistor fully differential Doherty power amplifier (DPA) is investigated. Three active devices are combined in a very judicious way to amplify the differential signal in a way like what a typical Doherty
amplifier does. Particularly, two out-of-phase carrier PAs are applied to operate in the low-power region for high efficiency. On the other hand, only one peaking PA is used in the high-power region, which shares its output evenly
with the two carriers. The reduction of transistor number from four for a classic differential DPA to three greatly cuts down the realization cost and compacts the overall circuit. Theoretical analysis is given for deep understanding of
the operation principle. To demonstrate the proposed technique, a prototype is implemented based on Cree’s CGH40010 GaN HEMTs. Experimental result shows that 73% and 63% drain efficiencies are achieved at peak power and
6-dB back-off point, respectively.

A 5 GHz-band direct digital RF modulator using current-mode DAC with idle current is proposed and fabricated in 90-nm CMOS process. Since this modulator directly converts digital BB parallel input signal into RF signal, small die
size and low dc operation can be achieved. To reduce the higher order distortion components at the RF output, idle current is provided to BB current output from the current-mode DAC. By providing idle current of 10% of full scale
DAC output current, the 2nd and the 3rd order distortion components near 5 GHz-band carrier are reduced and the improvement of ENOB is achieved. As the results, measured ENOB of 6.36 bit (SNDR of 40.0 dB) with RF modulated

H. W. Zhang, Q. Xue, City University of Hong Kong, Hong Kong, Hong Kong
A novel Gysel power divider with arbitrary power ratio for high-power application is presented in this paper. The power dividing ratio can be conveniently assigned by controlling the length of two branch lines without any changes
in other branches. The characteristics of all the transmission lines in this divider are fixed to the same value based on the theoretical analysis, which will simplify the design procedure of unequal Gysel power. Besides, the power ratio
in this Gysel power divider can be designed from 0 to infinite without employing high impedance transmission line, which is unrealized in the conventional Gysel power divider. In order to evaluate the performance of the novel Gysel
power divider, two dividers with dividing ratios of 2:1 and 4:1 are fabricated and examined. From the results it can be observed that there is excellent agreement between the simulated and measured results.

This session presents the latest research achievements of compact and switchable filters for microwave andmillimeter-wave applications. With the help of new technologies, such as MEMS and silicon bulk micromachining, novel filter structures are proposed and advanced filtering performances are achieved. These include: aminiaturized filter based on new quadruple-mode ring resonator with overlapping structure with quasi-elliptic

T. Lin1, J. Kuo2, S. Chung1, 1National Chiao Tung University, Hsinchu, Taiwan, 2Chang Gung University, Taoyuan, Taiwan
A compact quadruple-mode ring resonator is proposed for synthesis of a quasi-elliptic bandpass filter. The
resonator is composed of four half-wavelength rings connected to a single grounded via. For miniaturization,
the ring areas are overlapped and the crossovers are implemented by short CPW sections in the ground plane.
As a result, the resonator uses about 50% area of a conventional dual-mode ring resonator filter. Among thefour rings, all coupling coefficients are of inductive type realized by shorted high-impedance and coupled-line
sections. Two zeros are created by capacitive source-load coupling, and the response is synthesized by the coupling matrix method. Agreement between simulation and measurement results of a realized circuit validates
the approach.

The UWB filter is realized using a ring resonator which is loaded with two sets of stubs, i.e. one is loadedin the center and two little stubs at the symmetrical side locations. The loaded stubs are used to create transmission zeros in upper stopband thus high modes are suppressed greatly. Moreover, two identical meandered

i.e. negative refractive index. Moreover, its cell size is about 330 times smaller than the resonant wavelength.
By applying one or two metamaterial slabs between the two traditional inductive coupling copper rings, thetransfer mechanism will be changed to be resonant coupling. Therefore, both of the transfer distance and thetransfer efficiency are improved significantly.

The paper discusses the bandwidth extension of a second-harmonic tuned GaN Doherty power amplifier: theadopted strategy relies on output wideband compensation stages and input broadband matching. The single-band (3.5 GHz) and the wide-band (3-3.6 GHz) power amplifiers are compared in terms of building blocks
design strategy. The performances, experimentally characterized in single- and two-tone conditions, are close
to the state-of-the art for these applications, and confirm the validity of the bandwidth extension approach.
In fact, output power of more than 43dBm and 6 dB back-off efficiency of around 40% are maintained by the
bandwidth extension strategy, as well as intermodulation ratio values. Furthermore, digital baseband predistortion is successfully applied to both stages.

A Compact Fully Differential Doherty Power Amplifier
S. Chen, Q. Xue, City University of Hong Kong, Kowloon, Hong Kong
In this paper, a compact triple-transistor fully differential Doherty power amplifier (DPA) is investigated. Three
active devices are combined in a very judicious way to amplify the differential signal in a way like what a typical
Doherty amplifier does. Particularly, two out-of-phase carrier PAs are applied to operate in the low-power region for high efficiency. On the other hand, only one peaking PA is used in the high-power region, which shares
its output evenly with the two carriers. The reduction of transistor number from four for a classic differential DPA
to three greatly cuts down the realization cost and compacts the overall circuit. Theoretical analysis is given fordeep understanding of the operation principle. To demonstrate the proposed technique, a prototype is implemented based on Cree’s CGH40010 GaN HEMTs. Experimental result shows that 73% and 63% drain efficiencies
are achieved at peak power and 6-dB back-off point, respectively.

100W output power, 22dB gain with 40% power-added-efficiency from 100MHz to 3,000MHz. This performance is achieved by tailoring both the device impedance and by using unique wide-band circuit matching

Generalized Twin-Nonlinear Two-Box Digital Predistorter for GaN Based LTE Doherty Power Amplifiers with Strong Memory Effects
O. Hammi1, M. S. Sharawi1, F. M. Ghannouchi2, 1King Fahd University of Petroleum and Minerals, Dhahran, Saudi
Arabia, 2University of Calgary, Calgary, Canada
In this paper, a generalized twin-nonlinear two-box predistorter is proposed for the linearization of highly nonlinear Doherty power amplifiers exhibiting strong memory effects. The proposed predistorter is made of thecascade of a memoryless look-up table followed by a generalized memory polynomial function and thus can beseen as a two-box implementation of the generalized memory polynomial model. The generalized twin-nonlinear two-box predistorter is experimentally benchmarked against the generalized memory polynomial model.
The linearization performances of both models when applied on a GaN based Doherty power amplifier driven
by a 20MHz LTE signal, demonstrate the superiority of the proposed predistorter which achieves better linearity
performance while requiring a lower number of coefficients. Indeed, an extra 5dB is obtained in the ACLR while
the number of predistorter coefficients is reduced by more than 60%.

Abstract — This paper presents an approach of characterization of substrate material using complementary
split ring resonator (CSRR). Frequency selective surfaces made from CSRR are excited with free space radiation.
The dielectric properties of substrate material can be extracted from resonant frequencies and transmission loss
at resonant frequencies. In order to verify the proposed method, the complex permittivity of Silicon substrate ismeasured from 110GHz to 180GHz by using backward-wave oscillator (BWO) spectrometers. And the measurement results show that the dielectric properties of Silicon substrate remain almost the same as that provided bysemiconductor foundry at microwave frequencies.

T. Kao, J. Lin, University of Florida, Gainesville, United States
Non-contact vital sign detection using 60-GHz radar offers various advantages such as higher sensitivity andsmaller antennas compared to lower-frequency systems, however, the respiration amplitude comparable towavelength causes strong non-linear phase modulation, and relatively small heartbeat amplitude results in detection difficulty. In this paper, theoretical analysis and simulation of 60-GHz detection are provided to addressthese issues. Both shallow and deep breathings are tested in the experiments, and the detection techniquemonitoring both the fundamental and second harmonic of respiration is proposed. The phenomena explainedin the work can be applied to many millimeter-wave Doppler radar applications where target displacement iscomparable to or larger than the wavelength to ensure robust detection.

Body centric wireless communications are now a well-established field of research. Most of the available work
is focused on frequencies up to 12GHz, and covers various aspects concerning the communication, from signal
propagation to antenna design. Recently, the interest over V and W bands has been growing, due to the presence of unlicensed portions of the spectrum, and the ever increasing availability of compact devices working
at millimeter wave frequencies. The knowledge about the effects of the proximity of the human body on thecommunication channel at such frequencies is still extremely limited.

South Bend, United States
In this work we provide a new outlook on plasmonic effects in periodically patterned semiconductor ribbons.
Based on the classical electromagnetic theory we develop an analytical model to represent these effects andshow that: 1. THz plasmons can be excited at room temperature in periodically patterned semiconductor 2DEGs(regardless of the semiconductor material); 2. its strength and frequency dependence heavily depends in thesurrounding dielectric environment. Moreover, we discuss how the plasmon resonance frequency and extinction magnitude can be effectively tuned by controlling the electron concentration and pattern size, which shows
great potential for THz signal modulation.

Reliability of MEMS Capacitive Switches
J. C. Hwang1, C. L. Goldsmith2, 1Lehigh University, Bethlehem, United States, 2MEMtronics Corporation, Richardson, United States
This paper reviews the progress over the past decade in improving the reliability of MEMS capacitive switches.
The emphasis is on mitigating the dielectric-charging problem as it currently limits the lifetime of these switches. The most critical is to distinguish charging of the dielectric surface from that of the dielectric bulk, and thenmitigate them separately. Once surface charging is eliminated and bulk charging is greatly reduced, the switch
lifetime can be prolonged almost indefinitely by using an intelligent closed-loop CMOS control circuit. This will
facilitate the use of MEMS capacitive switches in military and commercial systems.

In this work, an analytical current transport model of a Graphene Nanoribbon (GNR) Tunnel Field Effect Transistor (T-FET) is presented considering drain source voltage (VDS), gate source voltage (VGS), carrier mobility(μ) and top gate dielectric (tOX). For a GNR width of 5nm at 0.275eV band gap, ON current of 1605 µA/µm is
calculated with a very high ON/OFF current ratio of 10^7. Subthreshold slope of 7.07mV/decade is calculated

In thispaper, an RF frequency doubling tag was used for detecting small displacement with high accuracy. A heterodyne and a homodyne quadrature radar receiving systems were used to detect small scale tag motion and nontagged motion from a distance, respectively.

Y. Gao1,2, Y. Li1, S. Zhou1, Y. Li1, H. Yu2, 1Tsinghua University, Beijing, China, 2Information Engineering Institute,Zhengzhou, China
Energy consumption in current cellular commu-nication systems becomes more and more critical with the demand for higher throughput and explosive growth of terminal equipment. However, the consumption is evitable in low traffic load time or area, e.g. in late-night. In order to reduce system energy consumption, power off
low load base stations is an easy and effective way to reduce energy consumption, but lead to the problem ofdamaging the coverage performance. In this paper, we studied the effect of adjusting mechanical tilt angle andtransmit power of base stations in an ergodic way after shut down adjacent idle base stations. Compared withtraditional shutdown method, the changing of mechanical tilt and transmit power jointly can effectively help
maintain coverage and lower system power consumption. Evaluation has been done under the LTE-Advanced
system level simulation.

N. Chamanara, D. Sounas, C. Caloz, Ecole Polytechnique de Montréal, Montreal, Canada
The sheet resistance of graphene has been recently reduced below the level of previous optically transparent
conductive materials. With its additional advantage of mechanical flexibility and low cost, graphene is one of
the best candidates for future transparent electronics. We investigate here the possibility of using graphene fortransparent and flexible microwave structures. Specifically, we study the waveguiding and nonreciprocal properties of various planar microwave transmission lines, using the 2D finite difference frequency domain (FDFD)
technique. It is shown that reciprocal graphene based structures of acceptably low loss levels are achievableusing graphene sheets of the lowest available resistivity, on the other hand graphene based non-reciprocal
structures are accompanied by prohibitive loss due to a fundamental trade-off between nonreciprocity andcarrier density in graphene.

H. Zhu, J. Mao, J. Li, Shanghai Jiao Tong University, Shanghai, China
In this paper, a novel power plane of electromagnetic bandgap (EBG) structure for wideband mitigation of simultaneous switching noise (SSN) in mixed signal systems is proposed. Complementary split ring resonator(CSRR) with inherent filtering characteristic is utilized for constituting EBG unit cells. From the simulated andmeasured results of the proposed EBG structure, a wideband suppression of SSN ranges from 0.56 GHz to 5.88
GHz is achieved with a high mitigation level of -40 dB. Furthermore, the influence of the proposed power planeof EBG structure on the signal integrity (SI) is investigated in the time and frequency domains, respectively. The
results show that the SI performance can be improved significantly by using differential pairs for the signals.

A wideband multi-way out-of-phase substrate integrated waveguide (SIW) power divider with improved rejection band by using novel hybrid multiple-via probe and multiple radial slots has been presented in this letter.
The novel hybrid multiple-via probe and multiple radial slots are employed to achieve wideband and improved
rejection band respectively. An eight-way out-of-phase SIW power divider is designed, fabricated, and measured. Good agreement between simulated and measured results is obtained in the desirable frequency range.
The measured average insertion loss of the eight-way power divider is approximately 9.3dB and return loss isgreater than 15 dB from 3.5GHz to 8 GHz, as well as an rejection band with more than 25 dB attenuation from 9

L. Gao, X. Y. Zhang, B. J. Hu, South China University of Technology, Guangzhou, China
A novel planar tunable bandpass filter using the centrally-loaded short-ended resonator is presented in thispaper. Characterized by theoretical analysis, the proposed structure is founded to have the advantage that thefundamental frequency can be tuned while the second harmonic remains almost unchanged. By controllingthe voltage, the lower passband can be tuned in a wide frequency range. To demonstrate the purposed idea,

Compact LTCC Bandpass Filters Using Vertically Folded Half Wavelength Resonator
C. Shao, H. Tang, L. Zhou, J. Chen, Nantong University, Nan Tong, China
In this paper, a pair of novel compact low temperature co-fired ceramic (LTCC) bandpass filters (BPFs) based ontransmission line theory are proposed. The employed half wavelength (λg/2) resonator has been vertically folded
to form a multi-layer transmission line resonator for minimizing the circuit size significantly. Since there is a virtual ground in the symmetrical plane of the multi-layer resonator, the characteristic of the resonator keeps almost
unchanged. Transmission zeros have been realized near to the passband and in the stopband, which improve theselectivity and harmonic rejection of the BPFs. For demonstration, two BPFs centered at 3.1GHz and 10GHz aredesigned using the proposed resonator, and the circuit sizes are 5.1×3.9×1.8 mm3 and 4.0×3.9×1.5 mm3.

F. Ghezzo, Z. Zhao, R. Liu, Kuang-Chi Institute of Advanced Technology, Shenzhen, China
we describe the fabrication method used for packaging a 15cm x 15cm x 3cm polymer based beam splitter, ametamaterial device designed for operating at 17GHz. An injection molding technique was used to allow a low
viscosity resin, curing at room temperature, to package ten FR4 substrate layers with metamaterial patterns onthem. The metamaterial structures were designed and their distribution optimized on each layer in order toachieve the effect of splitting in two parts an electromagnetic wave impinging on the face of the component. A
low dielectric and low loss epoxy resin for casting and suitable for packaging was selected as the injection polymer. The design of the electromagnetic behavior of the component took into consideration the full integrationof the FR4 substrates into the polymeric host material. The measurements performed to verify the performanceof the as-fabricated prototype device are presented and the results are discussed in this manuscript.

A method of modeling spurious mode for microwave multiplexer design is presented. It is proved that the channel filter can be simplified to have the minimum structural features, yet still capable of modeling the effect of
spurious mode accurately, which facilitates the application of neural networks in the multiplexer design. Modelsimplification and neural model development are detailed. The method enables fast and accurate simulation of

H. Zhu1, S. Wong1, S. Wen2, Q. Chu1, 1South China University of Technology, Guangzhou, China, 2Nanyang Technological University, Singapore, Singapore
An ultra-wideband (UWB) bandpass filter is proposed in this paper. The proposed structure composes of two
pairs of microstrip short-circuited stubs which provide a microstrip-to-CPW transition, and a CPW resonator
whose length is about half-guided-wavelength (λg/2) at 6.85GHz. A triple-mode UWB bandpass filter is produced using this microstrip-to-CPW transition structure. In order to suppress WLAN signals around 5.2/5.8GHz,
a novel via-stub-loaded structure is designed. By adding this via-stub-loaded structure, a bandstop characteristic is formed as a notch-band whose position and bandwidth could be tuned easily. Simulation results indicatethat the reflection loss is lower than -15dB in desired passband, and it also achieves a good performance ofthe notch-band around 5.2/5.8GHz. Finally, the proposed UWB bandpass filter is fabricated and measured. The
measured results are in good agreement with simulated ones.

Z. Xia1,2, F. Liu1, 1University of Science and Technology of China, Hefei, China, 2Southwest University of Science andTechnology, Mianyang, China
A novel compact dual-band bandpass filter (DBPF) using SIRs with open-stub line and 0-degree feed structure ispresented in this paper. The low-band is obtained by using hairpin type Stepped Impedance Resonators (SIR) split
ring through electrical coupling，And by tuning a pair of open-stub lines the high-band is realized too. In order toimprove the stop band attenuation, zero-degree feed structure is implemented to introduce three transmission
zeros. So the proposed DBPF has high selectivity, and is also simple in design and compact in structure. Finally the
proposed filter is designed and fabricated, and the simulation and test results are in good agreement.

Research on Picosecond EMP Suppression Filter
B. Yuan, Y. Gao, T. Peng, P. Zhu, Shanghai Jiao Tong University, Shanghai, China
Picosecond EMPs’bandwidth and energy energy spread in a wide microwave spectrum may increase exponentiallyas pulse-width decreasing under 100ps.Thus picoseconds EMPs could have potential interference on other devices. Usually, using a narrowband filter is a useful method for their suppression. However, due to the existence of
their inherently parasitic pass-bands, the traditional microwave narrowband filters, when applied to picosecond
EMPs’ condition, lost their traits of narrowband.In this paper, we present the relationship between pulse-width andbandwidth, and that between pulse-width and ratio of energy spread in the microwave spectrum to whole energy,
which give a practical guidance for suppression filter design. Also, a special high-pass passive device is designed to
improve the traditional waveguide filter. The improved filter is easy to implement and experimentally validated toeffectively attenuate undesired signals’amplitudes by -20dB in every parasitic pass-band.

A fully tunable bandpass filter using tunable transformers and multiple mode resonators (MMRs) is proposed. The
proposed tunable MMR makes it possible to realize wide-band tunable filters. Thus the tuning ranges of the center
frequency and bandwidth are wide. The novel tunable transformer may help to get the desired external quality
factor (Qe) while the center frequency or bandwidth is tuned. Thus a good passband performance may be got.

Wide bandgap GaN technology has emerged as a major actor among technologies devoted to high frequency,
high power applications. However, GaN based transistors are still largely sensitive to damaging effects induced
by interface or surface charges, generally assigned to charge processes induced by spontaneous and piezoelectric effects. This paper presents recent works in the field of reliability on AlGaN/GaN HEMT (High Electron
Mobility Transistor), and is focused on the identification and location of activated defects using both pulsed
electrical signatures (time domain meas.) and low frequency noise spectra (frequency domain meas.). These
sets of measurements partially correlate and give evidence of short term as well as long term memory effects.
High thermal reverse bias (HTRB) stress has been applied to a set of devices, and the evolutions of the transistors’ electrical and low frequency noise signatures are investigated.

T. Hiltunen1,3, M. Lampinen2, M. Valkama3, 1Magister Solutions Ltd., Jyväskylä, Finland, 2Renesas Mobile Corporation, Oulu, Finland, 3Tampere University of Technology, Tampere, Finland
The feedback quantization has a considerable impact on the performance of precoded four branch High Speed
Downlink Packet Access (HSDPA) MIMO. With more transmit antennas, efficient quantization scheme is more
important and more quantization loss needs to be tolerated. In this paper, the performance of four branchdual-codeword single-user MIMO is evaluated assuming two different types of compact codebooks. First of thestudied codebooks is similar to the 4-Tx codebook used in Long Term Evolution (LTE) system and the second isa novel multi-granular codebook. An extension to the multi-granular codebook is also proposed. Simulation
results are presented assuming cross-polarized antennas. The link performance is compared to Release 7 2x2
MIMO and 4x2 MIMO with unquantized feedback. The studies show throughput gains up to 66 % for the LTE
codebook and up to 79 % for the multi-granular codebook compared to the 2x2 MIMO. The relative gains arehighest at low geometries.

J. J. He1, Q. Zeng2, 1Carleton University, Ottawa, Canada, 2Communications Research Centre Canada, Ottawa, Canada
The paper addresses the problem of constructing signature sequences for quasi-synchronous CDMA systems.
We employ two $\ell-ary$ sequences, i.e. $\ell$ symbols sequences, with ideal two-level autocorrelation anda Costas or Golomn Costas sequence to construct a signal set with long Low Correlation Zone length and low
maximum magnitude of correlation values. We obtain an Low Correlation Zone $(Np, p,p,N)$ signal set and an
Low Autocorrelation Zone $(Np,p,p,1)$ signal set, where $N$ is a positive integer and $p$ is a prime number. We
also get an LCZ $(p^m(p^m-1), p^m, p^m-1, p^m)$ signal set and an LACZ $(p^m(p^m-1), p^m, p^m-1,
1)$ signal set, where $m$ is a positive integer.

This scheme enjoys the integration oftwin-/triplet-antenna bit-level space-time (ST) codes with the binary turbo-like codes of unpunctured codecs. The

taking into account diode parasitic resistance. We consider both transit and injection time of electron since they

Accuracy-Controlled Convergence Criterion for Full Wave Simulation
W. Ding, G. Wang, X. Chen, Wuhan University, Wuhan, China
Full wave electromagnetic (EM) simulations frequently encounter low-frequency breakdown: for decoupling ofelectric and magnetic fields in low frequency, the impedance matrix degenerates into near singular matrix andcauses convergence problems. For absence of constraint between simulation accuracy and the convergence condition for iterative solver, excessively rigorous convergence condition were applied to ensure simulation accuracy,
as a result, this way leads to over convergence, i.e., converge at unnecessarily high accuracy and simulation time
doubly increases. By theoretically analyzing the impedance matrix, connection between simulation accuracy andthe relative residual error is established, and an accuracy-controlled convergence criterion is proposed. Numericalexperiments are included to demonstrate that this convergence criterion effectively avoids the occurrence of overconvergence yet insures simulation accuracy; therefore the simulation efficiency is visibly promoted.

Iterative Robust Beamformer with an Estimation of Uncertainty Level
T. Zhang, L. Sun, University of Science and Technology of China, Hefei, China
In this paper, a new design of the robust adpti-ve beamformer (RAB) is developed to overcome the increased
computation cost of the traditional RABs. This approach in-troduces a suboptimal of the distance between theactual arr-ay steering vector (ASV) the presumed ASV in tandem with the iterative doubly constrained robust
capon beamformer using fixed uncertainty level (Fu-IDCRCB). Then, the unce-rtainty level of the first iteration
is updated by the optimal distance and then the estimated ASV of the first step is in the vicinity of the actual
ASV. As a result, the coherent iterations are needed to search the actual ASV with smaller uncertainty set. Hence,
this method convergences faster than the other beamfomers (BFs) and the simulation results shown that theeffectiveness of the proposed BF.

Special Session: How to Write a Paper for IEEE MTT-S Journals and Navigate the Review Process
By George E. Ponchak
The careers of many people depends on their success in writing and getting their papers published. More important, the scientific process requires that scientific findings be
published so that other researchers may build on your ideas or refute your findings. If authors are not able to publish their papers, then their careers are hurt and scientificprogress slows and stops. Therefore, it is critical that researchers and engineers understand the process of writing and getting published their papers in reputable and cited
journals and scientific conferences. However, often, authors’ papers are rejected because they did not understand what reviewers, Associate Editors, and Editors are looking
for in a paper, even if the technical results are good.
This presentation will cover the steps that an author should take to increase the acceptance rate of their papers in journals and conference. It will cover the reasons mostpapers are rejected and how an author should organize their paper to avoid those reasons. Lastly, it will present what steps you should take if your paper is rejected to get
it published in the same journal or in a different journal.

Optimization is followed by sensitivity assessment wherein Monte Carlo simulations and corner analysis are performed on the Pareto points with respect
to process variations. The algorithm is validated in the design of RTWO whose frequency varies between 3 to
5GHz due to varying dimensions of coupled transmission line. The optimization is a two step process. A neuralnetwork is developed from experimental data to estimate phase noise and power with transmission line widthand spacing as inputs.

The monolithic variable delay line with the loss compensation is presented. The operation of the delay line
relies on changing the impedance of two identical reflection-loads at the through and coupled ports of thedirectional coupler. The reflection-load is the composite network, consisting of a passive parallel resonator, anda frequency-selective negative resistor. The negative resistor maintains the quality factor of the resonator to

K. W. Eccleston, University of Canterbury, Christchurch, New Zealand
The half-mode corrugated substrate integrated waveguide (HMCSIW) uses an array of quarter-wave stubs inplace of vias to artificially create an electric wall. This structure supports the TE0.5,0 mode encountered in thehalf-mode substrate integrated waveguide (HMSIW). The top conductor of the structure is isolated from groundat dc permitting integration of active devices at the open edge. An eigenvalue formulation was used to study
the mode behavior of the HMCSIW. Simulations and experimental results for an X-band HMCSIW were used tovalidate calculations. Unlike the HMSIW, a spurious mode restricts monomode operation to one octave.

G. Sajin1, I. Mocanu1,2, M. Carp1, 1National Research Institute for Microtechnologies, IMT Bucharest, Bucharest,
Romania, 2Politehnica University Bucharest, Bucharest, Romania
The paper describes a method of return loss (RL) reducing for a CoPlanar Waveguide (CPW) Composite Right/
Left-Handed (CRLH) zeroth-order resonance (ZOR) mm-wave antenna by matching the radiating structure impedance ZS = RS + jXS to the characteristic circuit impedance Z0 = 50 Ohm. The working frequency is f = 40
GHz and the initial RL value was S11 = -16.21 dB, meaning a VSWR = 1.37. Using appropriate formulas, theresistive RS and reactive XS parts of ZS were found. The second step was to find the length l of a short-ended
parallel reactive stub and the suitable point d for stub implantation in order to match the antenna to the characteristic impedance Z0. With these data, the layout of the antenna feeding line was modified by adding theappropriate matching stub. After that, the return loss at the feeding line input was S11 = -43.50 dB. The returnloss was drastically improved, demonstrating effectiveness of the matching process.

T. Y. Yang, W. Hong, Y. Zhang, Southeast University, Nanjing, China
A 16x17 slot antenna array based on SIW technique with a novel balance dual-feeding scheme. The proposed array consists of 16 longitudinal slot sub-arrays, and each sub-array has 17 radiation slots. Balanced dual feeding
scheme is introduced to excite each sub-array from its both terminals with equal phase and amplitude to ensure
the radiation pattern of the sub-array is stably steering to the normal direction over the entire operating band.
Two 16-way power dividers are used to unit sub-arrays. Another T-shaped power-divider is used to combine thetwo 16-way power dividers into one port. Thus, the finalized antenna array has only one port but its radiation
pattern is independent to frequency. The antenna array is implemented based on standard PCB process and both
CPW-SIW and rectangular waveguide-SIW transitions are designed for the measurement. The measured maximum gain of the antenna array achieves 26.9 dBi, and the measured bandwidth of -10 dB is 40.5~43.5 GHz.

T. Wang1, L. Song1, Z. Han2, J. Zhang3, X. Zhang3, 1Peking University, Beijing, China, 2University of Houston,
Houston, United States, 3ZTE Corporation, Shenzhen, China
In this paper, we consider a cognitive relay network, in which multiple pairs of secondary users (SUs) share theunlicensed spectrum by the overlay mode, and for each SU pair, the two ends exchange data via a common
relay node that senses the spectrum and allocates the unused bandwidth. Here, we formulate the spectrum
allocation problem as a multi-object auction and introduce the mechanisms of sequential first price auction(SFPA) and sequential second price auction (SSPA), where for each mechanism, the optimal bidding strategy isanalyzed and the corresponding algorithm is given. Simulation results show that both the proposed algorithms
cost only 25%~35% feedback overhead, but achieve about 95% total transmission rate (with SSPA having aslightly better performance), compared with the optimal algorithm.

For situations differing about how receiving nodes know about messages forthe other, we accordingly determine the channel capacities and the coding process using techniques such as

University of Singapore, Singapore, Singapore
This paper studies the opportunistic spectrum access (OSA) of secondary users in a large-scale overlay cognitive
radio (CR) network. Particularly, a threshold-based protocol is investigated, where the secondary transmitter isallowed to access the spectrum only if the maximum signal power of the received pilots sent from the primarytransmitters is lower than a certain threshold. To measure the resulting transmission opportunity for the secondary users by the proposed OSA protocol, the concept of spatial opportunity is introduced and evaluated byapplying tools from stochastic geometry. Based on this result, approximations on the coverage probabilities ofthe primary and secondary networks under the proposed OSA protocol are characterized. Simulation results areprovided to validate our analysis.

Multiuser Diversity of Spectrum Leasing in Cognitive Radio Networks
C. Zhai, W. Zhang, The University of New South Wales, Sydney, Australia
In this paper, an adaptive spectrum leasing scheme is proposed for multiuser cognitive radio networks and multiuser diversity is analyzed. Based on two-path successive relay and decode-and-forward relay protocols, eachcognitive user intelligently switches the spectrum leasing protocols to help the primary data transmission. As
a reward, the spectrum is then leased to the cognitive user for secondary data transmission. The best cognitive
user that achieves the largest secondary rate while satisfying the primary rate target is selected in the spectrum
leasing. The multiuser diversity of the spectrum leasing scheme is analyzed and the throughout is shown to be
proportional to loglog(m) for large number of m cognitive users.

Abstract—A 5 GHz-band direct digital RF modulator using current-mode DAC with idle current is proposed andfabricated in 90-nm CMOS process. Since this modulator directly converts digital BB parallel input signal into RF
signal, small die size and low dc operation can be achieved. To reduce the higher order distortion components
at the RF output, idle current is provided to BB current output from the current-mode DAC. By providing idle
current of 10% of full scale DAC output current, the 2nd and the 3rd order distortion components near 5 GHzband carrier are reduced and the improvement of ENOB is achieved. As the results, measured ENOB of 6.36 bit(SNDR of 40.0 dB) with RF modulated output power of -28.4 dB is obtained at 5 GHz. The core size of the proposed modulator integrated circuit (IC) is 200µm x 200µm and the power consumption of core circuit excluding

A novel Gysel power divider with arbitrary power ratio for high-power application is presented in this paper.
The power dividing ratio can be conveniently assigned by controlling the length of two branch lines without
any changes in other branches. The characteristics of all the transmission lines in this divider are fixed to thesame value based on the theoretical analysis, which will simplify the design procedure of unequal Gysel power.
Besides, the power ratio in this Gysel power divider can be designed from 0 to infinite without employing highimpedance transmission line, which is unrealized in the conventional Gysel power divider. In order to evaluate
the performance of the novel Gysel power divider, two dividers with dividing ratios of 2:1 and 4:1 are fabricatedand examined. From the results it can be observed that there is excellent agreement between the simulated

Formulation of Realizable Scattering Matrices for Multiplexers with Contiguous Bands
A. Garcia-Lamperez, S. Llorente-Romano, M. Salazar-Palma, Universidad Carlos III de Madrid, Leganés, Spain
Compact multiplexers are a class of multiport networks entirely formed by coupled resonators, with no additional elements, as junction structures or transmission line lengths. The synthesis of their coupling matrices
require the formulation of scattering coefficients as rational functions that verify the realizability conditions. A
solution is to approximate the reflection coefficients as the ones of isolated filters, and then to reconstruct thetransmission coefficients. This approach is quite robust when the pass bands are clearly separated, but additional care must be taken when they are contiguous. In particular, phase offsets should be applied to the isolated
filters responses. The effect of these phase shifts can be compensated after the coupling matrix synthesis.

A zero index metamaterial lens (ZIML) is proposed for antenna directivity and gain enhancement. The zero index
metamaterial (ZIM) is constructed from both electric metamaterial with near-zero permittivity and magnetic
metamaterial with near-zero permeability. The ZIM unit cell is numerically simulated. The scattering parameters show that there is a wide pass band where both permittivity and permeability are small enough to achieve
wave collimation. Particularly, both of the two parameters are of the same value, which makes the relative
characteristic impedance to be 1 and match that of air. A patch antenna and an H-plane horn antenna arealso implemented to examine the directivity and gain enhancement ability of the ZIML. The E-plane radiation patterns are both sharpened greatly. The gain enhancement of the two antennas are 6.6 dB and 4.3 dB,
respectively. The universality of the ZIML for the two antennas indicates a more flexible application of the ZIML
compared with traditional ones.

P. Cheong1, K. Wu2, D. Deslandes3, K. Tam1, 1University of Macau, Macau, Macau, 2École Polytechnique deMontréal, Montreal, Canada, 3University of Quebec in Montreal, Montreal, CanadaThis paper presents a new concept of simultaneous data transfers with existence of multiple harmonic frequency channels. This proposed harmonic communication system reuse the intermodulation products generated by
the intrinsic property of nonlinear devices, primarily the up-/down-converting mixers in the transceiver. In thiscase, duplicated data can be transferred through multiple frequency channels. Moreover, compact multiband
components can be used to replace those single-band circuits in conventional multiband systems and therefore
limiting the cost of such transceiver. In theoretical analysis, the optimal signal-to-noise ratio (SNR) performancecan be enhanced by 3-dB whenever the number of frequency channels is doubled. As the consequence, the biterror-rate (BER) performance can be improved, or in another point of view, the minimum required SNR for thereceiver can be relaxed. The simulation results show good agreements with the theoretical ones.

Wireless Power Transfer Technologies
Organizers: Franklin Bien, UNIST

Abstract: Wireless power transfer (WPT) is a breakthrough technology to provide the energy to communication devices without the power units. With the remarkableprogress being made recently, this technology has been attracting a lot of attention of scientists, engineers and R&D firms around the world. The concept of WPT traces backto the early 20th century when Nikola Tesla patented several techniques by which power could be transmitted. However, there was never strong demand for it due to thelack of applicable market such as charging a portable consumer electronics devices. Recently, the usage of mobile appliances such as cell-phones, PDAs, laptops, tablets, andother handheld gadgets, equipped with rechargeable batteries has been widely spreading. Additionally, environmentally friendly cars are being equipped with rechargeablesecondary batteries that could benefit from WPT technologies. In this workshop at IWS 2013, fundamentals and theories that could facilitate the WPT technology is widely

Computational Multi-physics Methods and Applications for Advanced RF Micro/Nanoelectronic Devices and Interconnects
Organizers: Prof. Wen-Yan Yin, Zhejiang University, Shanghai Jiao Tong University
Abstract: Advanced RF Micro/Nanoelectronic Devices and circuits are inherently multi-physics in nature. Electrical analysis, in particular, does not exist in its isolation
since interaction between multiple domains is required. Rather, other physical effects, like heat transfer and even mechanical stress, can have a large impact on theirperformance. For this reason, R&D of advanced RF micro/nanoelectronics devices, circuits and systems are now adopting tools that can help innovate beyond the more
traditional limited scope of electromagnetics-only simulation tools, with all relevant physical field effects treated in some appropriate way.
This workshop will be focused on the presentations of several computational multi-physics methods and their successful applications for various RF micro/nanoelectronics
devices, interconnects and circuits made of different materials, miniaturized passives with high performance, thin film active devices and 3-D interconnects or 3-D
transmission structures arising in high density 3-D integration for wireless communication. Also, fundamental physical principles changing with scales will be introduced
and discussed. From high frequency asymptotic approximation to quasi-static modeling, from classical electromagnetic phenomena to surface plasma and Casmir force,from electrical simulation to electrical-thermal co-simulation, this talk intends to review several key physical phenomena and corresponding mathematical models
emerging from RF micro/nanoelectronics.

Digital Techniques for Power Amplifiers Linearity and Efficiency Enhancement
Organizers: Dr. Oualid Hammi, KFUPM, KSA
Dr. Wenhua Chen, Tsinghua University, China
Abstract: Radio Frequency power amplifiers (PAs) are key components in wireless transmitters as they affect the overall performance in terms of linearity and efficiency.
Linearity specifications must be met in order to satisfy the regulatory spectrum emission masks. At the same time, power efficiency needs to be increased not only in orderto reduce the capital and operating expenses of wireless communication infrastructure but also to reduce the carbon footprint of wireless communication systems. Thus,
enhancing the PA efficiency is an important research avenue that will enable greener communication infrastructure.
Recently, the synergetic design of the RF power amplification stage and the digital signal processing led to high performance amplification systems in a wide variety ofconfigurations such as conventional single input power amplifiers, envelope tracking systems, dual-input amplifiers as well as dual-band PAs. Digital signal processing
techniques were successfully used to drive the amplifiers with the appropriate signals that will optimize the linearity and/or emulate power efficient mode of operation.
This workshop will thoroughly cover the various approaches that have been recently proposed for the enhancement of PAs linearity and power efficiency through digital
signal processing techniques. It will illustrate how the performances of several power amplification structures can be improved by the use of proper signal processing
techniques that can go beyond conventional digital predistortion. In the morning session of this full-day workshop, digital predistortion of single input PAs will be discussed
from various aspects. The afternoon session will be devoted to dual-input power amplification systems.
Eight speakers with internationally recognized expertise in the area of power amplifiers design and linearization have agreed to contribute to this workshop as shown below
in the list of presentations. The workshop is expected to attract a high number of attendees as this topic is of prime interest to researchers from academia and industry.

Implantable and Wearable Wireless Medical Devices and Systems
Instructor: J.-C. Chiao
Summary: Radio frequency identification has been utilized to increase efficiency and care quality in hospitals for patient information management, drug and equipment
inventory, scheduling and staffing. To further improve healthcare, enabling new diagnosis and treatment while aiming to reduce costs, major technical challenges still
exist. Limited sampling and acquisition of physiological parameters during the interaction period for caregivers and patients provide incomplete information about thepatients. Better care with higher diagnosis accuracy can be provided if more and time-lapsed data can be obtained without causing patients discomfort or limiting theirmobility.
Wireless technologies bring promising solutions to the aforementioned issues. Low-cost portable wireless electronics have made significant impacts to our societies.
Furthermore, recent advances in micro- and nano-technologies provide unique interfacing functionalities to human tissues, and advantages such as miniaturizationand low power consumption enabling novel applications in medicine and biological studies. Interfaces between biological objects and electronics allow quantitative
measurement and documentation of physiological and biochemical parameters, and even behaviors. The interfaces also provide direct control or modification of cells,
tissues, or organs by the electrical circuits making it possible to manage chronic diseases with a closed loop between biological objects and computers. With wirelesscommunication, implantable devices and systems make the interfacing possible for freely behaving animals or patients without constrains, discomfort or limits in mobility.
This increases the study or diagnosis accuracy in realistic environments as well as permits remote synthesis of physiological functions and delivery of therapeutic treatment.
