Authors: Nono Suprayetno  , Priyono Sutikno  , Nathanael P. Tandian  , Firman Hartono
Published: August 2021

This study aims to design an axial turbine rotor blade and predict the turbine performance at preliminary design stage. Quasi three dimensional method was applied to design including blade to blade flow analysis. The blade profile uses a NACA 0015 airfoil by varying the profile thickness from hub to tip. The profile is divided into eleven segments which has different parameters. The profile was analysed using blade to blade flow/cascade flow analysis called vortex panel method to obtain lift coefficient. The analysis of cascade flow was performed in potential flow and prediction of turbine perfomance is carried out involving common best practice to give drag effect on the blade. The design of the turbine was applied on three different rotors, which also have a different discharge, head, and design rotation. The outer diameter of turbine 1 is 0.65 m, while turbine 2 and turbine 3 have an outer diameter of 0,60 m. The calculation result show that the efficiency of turbines 1, 2, and 3 were 88,32%, 89,67%, and 89,04%, respectively.

Published: August 2021

In this study, the unsteady boundary layer flow over a stretching/shrinking cylinder immersed in nanofluid with the presence of suction effect is analyzed. The governing partial differential equations are converted to ordinary differential equations by introducing similarity transformation variables. The shooting method is applied to solve the system where the numerical solutions are obtained and presented graphically. The study's objective is to investigate the effect of nanoparticle volume fraction, the unsteadiness parameter, the stretching/shrinking parameter on the velocity and temperature gradients. It is found that the dual solutions are obtained in a specific range of these parameters for both stretching and shrinking cylinders. Besides, a high volume of the nanoparticle in the base fluid increases the velocity gradient and decreases the temperature gradient at the surface. Also, increasing nanoparticle volume fraction in the base fluid expands the solution's range, which denotes the boundary layer separation from the surface has been delayed. The existence of dual solutions allows stability analysis performance by introducing a new dimensionless variable and is solved using bvp4c function in Matlab software. This phase obtains the smallest eigenvalue, showing that the first solution is stable and physically realizable while the second solution is not stable.

Published: August 2021

An optimal design of an aligned configuration using a vertical axis wind turbine especially a crossflow wind turbine to increase rate and power production is one of the problems in wind energy. In the present work, an experimental investigation is presented to evaluate the impact of the wake effect on the dynamic performance of an aligned configuration and compared characteristics of the crossflow wind turbine for 12 x 12 number of blades. In arrays, the spacing parameters of the crossflow wind turbines were conducted with three different spacings (1D; 2D; and 3D) where a crossflow wind turbine was operating downstream of a co-rotating pair. The crossflow wind turbines arranged in inline configurations. Experiments were carried out in a closed-circuit WT-30 aerodynamic laboratory wind tunnel in a ratio velocity of 7.51 m/s. Measurement data of each wind turbines were reported in terms of dimensionless power coefficient (CP) and torque coefficients (CT) for dynamic performance analysis. The experimental results were aligned configuration spacing and the number of blades affects enhancement aerodynamic performance of the downstream crossflow wind turbines. The best performance turbine spacings in aligned configurations are 3D. Wind flow has a distance to be streamlined.

Published: August 2021

The study explores the performance characteristics of a Z-Blade reaction type water turbine and investigates a test unit for an ideal and practical case using the governing equations derived from the principles of conservation of mass, momentum, and energy. Various analyses are conducted with consideration of the ideal and possible operating condition for low-head (3 m to 5 m) and low-flow (2.5 L/sec and below) water resources. The relationship of the fluid flow friction known as k-factor with mass flow rate and angular velocity for a Z-Blade turbine model is discussed. The measured performance of two PVC pipe sizes (0.5 inch and 1 inch) of a Z-Blade turbine is presented and evaluated against theoretical results. This work also describes the simple concept of a Z-Blade turbine for a pico-hydro application. A large variation in k-factor with a 1% difference in rotational speed and mass flow rate is presented. The coefficient k-factor is also demonstrated as a strong parameter influencing the mass flow rate and rotational speed performance. This coefficient also has a significant impact on the conversion of potential energy into power output.

Responsabilidade civil e a autonomia privada do paciente
Authors: Santana Thaís
Published: August 2021

O presente artigo possui a finalidade de promover um raciocínio crítico acerca da autonomia privada do paciente e a efetivação do direito de não saber a partir da efetivação do direito à intimidade, analisando a responsabilidade civil médica. Para tanto, serão abordados aspectos da vida privada e a sua relação com o direito à intimidade, de modo a evidenciar os limites e possibilidades da autonomia privada, especificamente na esfera da saúde. Essa temática não possui entendimento pacífico pela doutrina e pelo Poder Judiciário, sendo divergentes as compreensões acerca da divulgação de informação não requisitada pelo paciente uma vez que, muitas vezes, este não está preparado para lidar com o recebimento de informações relacionadas à sua esfera privada. Busca-se, com esse artigo, evidenciar os argumentos sobre esses entendimentos de modo que se possa compreender um pouco mais sobre o direito de não saber. Além disso, busca-se salientar o indivíduo como ser autônomo e que possui livre escolha na sua vida privada, de modo que se possa falar na efetividade do Princípio da Dignidade da Pessoa Humana.

L’enclave et l’officiel
Authors: Vadot Guillaume
Published: August 2021

En s’appuyant sur les monographies comparées de trois complexes agro-industriels dans les années 2010 au Cameroun, l’article rend compte des processus qui ont vu ces espaces concédés à des entreprises entamer leur intégration au territoire politique. Dans un contexte marqué par les privatisations et l’augmentation des surfaces, il décrit le redéploiement à première vue surprenant des pouvoirs locaux et du langage de l’officiel au sein et aux abords de ces espaces isolés et enclavés. Pour cela, il suit le positionnement particulier des quelques cadres d’entreprises qui atteignent des formes de notabilisation à l’échelle locale. Il se penche également sur la sociogenèse, dans le creuset des relations sociales auxquelles donne lieu la plantation, d’institutions locales toujours plus nombreuses et reconnues par l’administration (collectivités locales, subdivisions administratives, chefferies de tous types). En faisant le récit des mobilisations qui ont affecté les entreprises de plantation ces quinze dernières années, l’article montre également que ces différents complexes, y compris le seul d’entre eux à avoir conservé son statut d’entreprise parapublique, ont été exposés à des revendications similaires et à l’imposition d’obligations sociales comparables envers leurs employé·es et les communautés riveraines. Entre bricolages et compromis, ces espaces ont ainsi suivi chacun à leur manière une trajectoire d’intégration au maillage politique du territoire tel qu’il s’est redéployé ces deux dernières décennies. L’article témoigne en ce sens du dynamisme des pouvoirs locaux au Cameroun dans le contexte d’une décentralisation politiquement verrouillée.
Hégémonie industrielle et économie morale dans une ville sidérurgique ukrainienne
Authors: Gorbach Denys
Published: August 2021

L’article interroge les configurations de pouvoir industrielles ( factory regimes ) à Kryvyi Rih, une ville minière et sidérurgique située à l’est de l’Ukraine. En s’appuyant sur un travail de terrain ethnographique, il retrace la reproduction de l’hégémonie industrielle au travers des transformations postsoviétiques (la privatisation et les mesures d’austérité). La comparaison de trois cas qui représentent des configurations hégémoniques différentes (des mines privatisées par des Ukrainiens, une aciérie achetée par une société étrangère et des carrières faisant partie d’une société ukrainienne intégrée verticalement) permet de repérer nombre de variations de ce processus, dues au degré d’autochtonie du nouveau propriétaire et à sa capacité répressive, au caractère des relations informelles dans le processus de travail et dans la scène syndicale, ainsi qu’à l’encastrement social du propriétaire à l’échelle de l’usine et au niveau urbain. L’article montre comment la construction et le maintien du bloc hégémonique entre le groupe dominant et des groupes subalternes à l’échelle de l’entreprise reposent sur une économie morale vernaculaire, dans laquelle sont encastrées les activités économiques de chaque entreprise. Le paternalisme industriel postsoviétique est le produit des attentes populaires, qui sont elles-mêmes dynamiques et susceptibles de changer sous l’influence des politiques des propriétaires légitimes.
Des frictions dans l’espace pétrolier
Authors: Buu-Sao Doris
Published: August 2021

La rencontre des peuples autochtones avec des entreprises minières ou pétrolières est souvent appréhendée au prisme de la confrontation. Si la fréquence des contestations est indéniable, notamment en Amérique latine, les interactions nées de l’implantation d’industries extractives en milieu rural ne se réduisent pas à l’opposition frontale : parce qu’elles s’ancrent nécessairement dans des espaces où elles doivent composer avec leur entourage social, ces industries donnent souvent lieu à des interactions plus routinières et pacifiées, porteuses de profonds changements. C’est ce qu’étudie cet article, qui s’appuie sur une enquête ethnographique menée au Pérou, dans des villages autochtones de l’Amazonie confrontés au développement d’un site pétrolier emblématique de la région. Il analyse comment cette industrie extractive ancrée localement contribue à la normalisation d’une société frontalière. Tenant compte du caractère relationnel des interactions qui se jouent aux abords des sites extractifs, il appréhende cette topographie politique comme un « espace pétrolier » où se jouent des transformations profondes mais ambivalentes, qu’il s’agisse de l’importation de la discipline salariale dans les pratiques productives, de la restructuration hiérarchisée du collectif villageois, ou de l’inscription dans l’ordre territorial national propice à une certaine marchandisation du foncier amazonien.
‘I loved to be included’ (Proverbs 1:8–19): The Church and Tiv Christian Youth Development
Authors: Uroko Favour C. , Enobong Solomon
Published: August 2021

This article examined the warning against evil companions in Proverbs 1:8–19 and the role of the church in addressing the involvement of Tiv youths in crime in Benue State and its implications for actions. Wicked people were zealous in seducing others into the paths of destruction. Would young people shun temporal and eternal ruin? This was the reason for Solomon’s instruction in Proverbs 1:8–19. He admonished his son with the caption ‘hear,’ which presented the son with a choice. However, Solomon implored the child to refuse to take any step in destructive paths of evildoers. The persuasive nature of the pericope was important in addressing the growing crime rate amongst Tiv youths in Benue State. Most youths in Tiv communities were being enticed into joining criminal gangs, secret cults and rituals in order to make quick wealth. Unfortunately, the number of youths in these immoral acts such as YahooYahoo amongst Tiv youths kept on increasing in the midst of the growing number of churches in most Tiv societies. Rhetoric analysis was used as the methodology. As part of recommendations, parents should instruct, discipline and stop their children from engaging in acts that lead to death. The youths should also avoid evil companions to avoid falling into trouble.Contribution: Youths are the leaders of tomorrow, which makes admonition to youths a necessity for the growth of the Tiv Society. Proverbs 1:8–19 provides roadmaps that Tiv leaders and the church could adopt in preserving morality among Tiv youths.

Authors: Muangwong Pooriwat , Chitapanarux Imjai , Ya-in Charin , Klibngern Hanpon , Kongmebhol Pailin
Published: August 2021

Background:

Kimura’s disease is a rare inflammatory disease that usually appears in head and neck region. We reported natural history of the disease and treatment outcome of radiotherapy (RT) in Chiang Mai University Hospital.

Methods:

A retrospective review was performed for all Kimura’s disease patients treated with radiotherapy at our center between 2002 and 2017.

Results:

A total of 20 patients with Kimura’s disease were reviewed. There were 14 men and 6 women. All patients presented with the mass in head and neck region. Eleven patients were treated with a definitive intent with RT, 9 patients were treated with RT after recurrence from other modalities. All patients were treated with local external beam RT with 2 Gy per fraction to a median total dose of 30 Gy (range 30–40). The median follow-up time was 4 years (range 1–16.5 years). One patient died from HIV opportunistic infection after 1.5 year of radiation with complete response of Kimura’s disease. Most of the patients responded to radiotherapy and controlled the disease at the time of analysis. Two patients had multiple recurrences at new areas outside radiotherapy field. Skin toxicity grade 1 was the most common late side effect which was found in 8 (44%) patients. We did not find severe late toxicity or second malignancy in this patient cohort.

Conclusion:

Good local control of Kimura’s disease can be achieved, with a radiation dose of 30–40 Gy, with insignificant late toxicities. We suggest that radiotherapy should be one of the treatments of choice for Kimura’s disease both in primary or recurrence setting.
Indigenous Groin Board Immobilization Reduces Planning Target Volume Margins in Groin Radiotherapy
Authors: Krishnatry Rahul , Mangaj Akshay , Bhajbhuje Rajesh , Murthy Vedang
Published: August 2021

Purpose:

To quantify the relative motion of pelvic and groin lymph nodes (PLN and GLN) and define indicative margins for image-guided radiotherapy based on bony anatomy for the frog-leg position (FLP) and groin immobilization board (GIB).

Materials and Methods:

Twenty patients with planning computed tomography (CT) scan and on treatment cone beam CTs (median = 8) for groin and pelvic radiotherapy were included in the study. Of these nine were treated with FLP and eleven with GIB. The PLN and GLN regions on the left and right were outlined in each scan. Systematic and random uncertainties were determined along with correlations between the motions of these regions. The clinical target volume to planning target volume (PTV) margins required to take motion into account was calculated for each immobilization.

Results:

The mean shifts for PLN and GLN were lesser but not statistically lower using GIB over FLP. There was significant concordance in the vertical, longitudinal and lateral motion of the pelvis and right groin (P = 0.015, 0.09 and 0.049, respectively), pelvis and left groin (P = 0.001, 0.048, and 0.006, respectively) and between left and right groin (P = 0.013, 0.01 and 0.07, respectively) for FLP and not GIB. The PTV margins required by Van Herk and Stroom's formula were reduced from 11 mm and 9 mm to 6 mm and 5 mm for pelvis; 12 mm and 11 mm to 7 mm and 6 mm for groin, respectively, using FLP over GIB.

Conclusions:

GIB brings concordance in shifts between pelvis and groin and between bilateral groins, thereby reducing the required PTV margins.
The Effect of Algorithms on Dose Distribution in Inhomogeneous Phantom
Authors: Tuğrul Taylan
Published: August 2021

Background:

The aim of this study is to evaluate the dose calculation algorithms commonly used in TPS by using MC simulation in the highly different inhomogeneous region and in the small fields and to provide the following uniquely new information in the study of correction algorithm.

Materials and Methods:

We compared the dose distribution obtained by Monaco TPS for small fields.

Results:

When we examine lung medium, for four different fields, we can see that the algorithms begin to differ. In both the lung and bone environment, the percentage differences decrease as the field size increases. In areas less than or equal to 3x3 cm2, there are serious differences between the algorithms. The CC algorithm calculates a low dose value as the photon passes from the lung environment to water environment. We can also see that this algorithm measures a low dose value in voxel as the photon passes from the water medium to the bone medium. In the transition from the water environment to the bone environment or from the bone environment to the water environment, the results of the CC algorithm are not close to MC simulation.

Conclusion:

The effect of the algorithms used in TPS on dose distribution is very strong, especially in environment with high electron density variation and in applications such as Stereotactic Body Radiotherapy and Intensity Modulated Radiotherapy where small fields are used.

Authors: Cheraghian Mojtaba , Pourfallah Tayyeb , Sabouri-Dodaran Amir Abbas , Gholami Mehrdad
Published: August 2021

Purpose:

The aim of this research was to calculate the fluence, dose equivalent (DE), and kerma of thermal, epithermal and fast photoneutrons separately, within ICRU soft-tissue-equivalent phantom in the radiotherapy treatment room, using MCNPX Monte Carlo code.

Materials and Methods:

For this purpose, 18 MV Varian Linac 2100 C/D machine was simulated and desired quantities were calculated on the central axis and transverse directions at different depths.

Results:

Maximum fluence, DE and kerma of total photoneutrons on central axis of the phantom were 43.8 n.cm-2.Gy-1, 0.26, and 3.62 mGy.Gy-1, at depths 2, 0.1, 0.1 cm, respectively. At any depth, average of fluence, DE and kerma in the outer area of the field were less than the inner area and in general were about 72%, 52%, and 45%, respectively.

Conclusion:

According to this research, within the phantom; variation of fluence, DE and kerma in transverse direction were mild, and along the central axis at shallow area were sharp. DE of fast photoneutrons at shallow and deep areas were one order of magnitude greater than thermal photoneutrons.
Comparison of Phase-Gated and Amplitude-Gated Dose Delivery to a Moving Target using Gafchromic EBT3 Film
Authors: Savanović Milovan , Jaroš Dražan , Foulquier Jean Noel
Published: August 2021

Introduction:

This study compared phase-gated and amplitude-gated dose deliveries to the moving gross tumor volume (GTV) in lung stereotactic body radiation therapy (SBRT) using Gafchromic External Beam Therapy (EBT3) dosimetry film.

Materials and Methods:

Eighty treatment plans using two techniques (40 phase gated and 40 amplitude gated) were delivered using dynamic conformal arc therapy (DCAT). The GTV motion, breathing amplitude, and period were taken from 40 lung SBRT patients who performed regular breathing. These parameters were re-simulated using a modified Varian breathing mini phantom. The dosimetric accuracy of the phase- and amplitude-gated treatment plans was analyzed using Gafchromic EBT3 dosimetry film. The treatment delivery efficacy was analyzed for gantry rotation, number of monitor unit (MU), and target position per triggering window. The time required to deliver the phase- and amplitude-gated treatment techniques was also evaluated.

Results:

The mean dose (range) per fraction was 16.11 ± 0.91 Gy (13.04–17.50 Gy) versus 16.26 ± 0.83 Gy (13.82–17.99 Gy) (P < 0.0001) for phase- and amplitude-gated delivery. The greater difference in the gamma passing rate was 1.2% ±0.4% in the amplitude-gated compared to the phase gated. The gantry rotation per triggering time (tt) was 2° ±1° (1.2°–3°) versus 5° ±1° (3°–6°) (P < 0.0001) and MU per tt was 10 ± 3 MU (6–13 MU) versus 24 ± 7 MU (12–32 MU) (P < 0.0001), for phase- versus amplitude-gated techniques. A 90 beam interruption in the phase-gated technique impacted the treatment delivery efficacy, increasing the treatment delivery time in the phase gated for 1664 ± 202 s 1353–1942 s) compared to 36 interruptions in the amplitude gated 823 ± 79 s (712–926 s) (P < 0.0001).

Conclusion:

Amplitude-gated DCAT allows for better dosimetric accuracy over phase-gated treatment patients with regular breathing patterns.
Nurse Retention in Workplace Adversity
Authors:   , Lewis Deborah
Published: August 2021

Practice Problem: Nurse turnover rate and lack of retention are issues that have an impact on safe patient care, patient mortality, quality outcomes, and patient experiences in the acute care units at the identified project setting. Turnover leads to excess labor utilization of overtime and increased hospital costs. PICOT: The PICOT question that guided this project was (P) In acute care hospital nurses, how do (I) nurse retention strategies (C) compared with no nurse retention strategies (O) reduce nurses’ intention to leave and increase job satisfaction over (T) eight weeks? Evidence: Twenty-one articles were reviewed that identified autonomy, recognition, acknowledgement, communication, and transformational leadership as nurse retention strategies, which contributed to a positive workplace environment and led to improved job satisfaction and nurse retention. Intervention: The intervention consisted of focused communication that included staff recognition and acknowledgement by the nurse leaders of each unit, which had a positive effect on the workplace environment and job satisfaction. Outcome: The results indicated a statistically insignificant change in job satisfaction and intent to stay yet did show a clinical significance. Conclusion: The benefit of the project was that there was a clinically significant change in behaviors including: verbal expressions of increased job satisfaction, notable positive attitudes and hopefulness, as well as staff resilience. Consistent leadership and a larger sample size may produce statistical significance in a future study.
Mindfulness-based Intervention and Relapse Rates in Adults with a History of Substance Use Disorder
Authors:   , Ross-Ansayo Tamieko
Published: August 2021

Practice Problem: Substance abuse disorder (SUD) has become an increasingly prevalent community health problem worldwide, affecting individuals in all geographical regions regardless of age, race, sex, and socioeconomic status, despite decades of efforts to find a solution (Bowen et al., 2014). A lack of treatment engagement and substance‐misuse crisis calls attention to the effectiveness of relapse‐sensitive care and treatments. PICOT: The question addressed in this evidence-based project was “ In adults over 18 years of age with substance use disorder (P), how does the effect of mindfulness-based treatment (I), compared with no mindfulness-based treatment (C), reduce the risk of relapse (O), in 3 months (T)?” Evidence: Evidence exists to support that Mindfulness-based intervention (MBI) significantly reduced the incidence of relapse in adult patients with a history of SUD by decreasing symptoms related to substance abuse craving or use. Intervention: Mindfulness-based practice consisting of meditation and mindful breathing exercises, motivational interviewing and relapse prevention cognitive therapy was implemented to reduce incidence of relapse in adults with a history of SUD. Outcome: Findings revealed a less than 15% reduction in incidence after three months of MBI implementation. Conclusion: The results indicate that the reduction in the risk of relapse in adult patients with a history of SUD post implementation was not significantly significant. The reduction also indicated a clinically significant improvement in relapse outcomes two months after implementing MBI.

The benefit of demand forecasting is to reduce the Bullwhip Effect, plan future resources, for example, such as stock management, place control, product distribution, and demand for raw materials so as to make the right decisions. The results showed that the linear regression method has better forecasting than the moving average because linear regression has a smaller error rate than the moving average. But even so, the error rate of this study is still very large, so it is necessary to do more research to minimize the error rate.

Authors: Li Xianqiang , Mao Kedan , Wang Ao , Tian Ji , Zhou Wenchuang
Published: August 2021

When a high-power very low frequency (VLF) communication system is in operation, the end of the antenna is in an alternating strong electric field environment. Due to dielectric loss, abnormal temperature rise may occur at the end of the antenna. To solve the
problem, analysis on the electric field distribution and temperature rising effect at the end of the antenna is first carried out in this paper. The factors that affect the electric field distribution and temperature rising, including the amplitude and frequency of the excitation voltage, the diameter of the antenna conductor and the material properties of the outer sheath of the antenna, are studied in detail. A novel approach to improve the
electric field distribution and to suppress temperature rising is proposed by designing a dielectric loss eliminator, and the effectiveness of the designed device is verified by simulation.

Published: August 2021

An innovative method is proposed to improve the cross-polarization performance and impedance matching of a microstrip antenna by integrating a complimentary split ring resonator and slots as a defected ground structure. An equivalent circuit model (ECM) enables the design take into consideration the mutual coupling between the antenna patch and the Defected Ground Structure. The input impedance and surface current density analysis confirms that the integration of a CSRR within a rectangular microstrip
patch antenna leads to uniform comparative cross-polarization level below 40 dB in the H-plane, over an angular range of ± 50°. Introducing parallel slots, as well, leads to a reduction of spurious antenna radiation, thereby improving the impedance matching. Measurements conducted on a fabricated prototype are consistent with simulation results. The proposed antenna has a peak gain of 4.16 dB at 2.6 GHz resonating frequency, and hence is good candidate for broadband service applications.

This paper is devoted to a novel Electromagnetic Band Gap (EBG) single-feed circularly
polarized microstrip EBG antenna with compact size proposed for C-Band applications. The antenna structure will include eight slits introduced at the boundary and the corners in the radiating square patch with a cross-slot at the center.

The provided study will effectively approve the various proposed structures and interest occupied by these types of antennas in the enhancement of output parameters (gain, directivity, radiation efficiency, and bandwidth) without much affecting the operating
bandwidth at C-band.

At first, the concept and the realization of a directive and circularly polarized antenna using an electromagnetic band gap material whose circular polarization is generated
by the structure itself is discussed. The analysis and simulation results are presented for an antenna operating at 6.1 GHz using computer Simulation Technologies (CST). Furthermore, the new compact circular polarized EBG antenna, compared to experimental results, will confirm the pre-studied goal of these kinds of antennas such as radiation efficiency, polarization purity, radiation efficiency, high directivity, and gain.

Published: August 2021

The implantable antenna is an important part of the wireless capsule endoscopy (WCE) system to achieve wireless communication. This paper designed an ultra-wideband flexible implantable antenna for wireless capsule endoscopy system. With a very wide bandwidth, the antenna can completely cover the industrial, scientific, and medical frequency bands (ISM, 2.4-2.48 GHz) and Wireless Medical Telemetry Service (WMTS, 1.395-1.4 GHz). The expanded size of the proposed antenna is 18mm× 10mm× 0.1mm. The conformal technology of the antenna has further reduced the space of the system
and achieved miniaturization. The capsule antenna in this paper is a compact planar monopole antenna fed by a coplanar waveguide, and it uses a flexible material as a
dielectric substrate to achieve the conformal shape of the antenna. U-shaped ground branch (UGB) and a loaded split ring resonator (SRR) structure were used to further
improve the antenna performance. Simulation and measurement results were basically the same. On the premise of radiation safety and miniaturization of the antenna, the ultra-wideband operation of the antenna was realized. This antenna design provided reference value for the design and application of the capsule antenna.
Complementary SRR-Based Reflector to Enhance Microstrip Antenna Performance
Authors: Ucar Mustafa
Published: August 2021

In this paper, complementary split ring resonator (SRR) based reflector to enhance the printed slot dipole (PSD) antenna performance is introduced. The numerically calculated return-loss, directivity and radiation pattern results of the PSD antenna, with (w/) and without (w/o) CSRR element etched on reflector plane are presented and investigated. Numerical analysis and modelling of the proposed design are carried out using CST Microwave Studio simulator based on the finite integration technique. According to the simulation results, with the inclusion of the CSRR-based reflector into the PSD antenna, the directivity is increased by values changes from 0.6 dB to 4.25 dB through the
operation band, while an improvement in bandwidth (~2.1%) is seen. It is also shown that this improvement in antenna performance is due to the -negative (ENG) behavior of CSRR structures. Prototype of the proposed antenna is fabricated using Arlon DiClad 880 substrate with electrical permittivity ofεr= 2.2. A quite good agreement between simulation and measurement is obtained. In this study, it is shown that the radiation
performance of the antenna can be increased easily by using the CSRR element as a reflector in the antenna structure with a new enhancement approach. Also, the proposed antenna with a compact size of 0.27λ× 0.41λ is appropriate for operating in IEEE 802.11b/g/n/ax (2.4 GHz) WLAN applications.
