San Diego, Calif., March 3, 2010—Pulse, a Technitrol Company (NYSE: TNL), introduces the first long-term evolution (LTE) antenna that can adjust to seven bands: LTE 700, 850, 900, 1800, 1900, 2100 and 2600 megahertz (MHz).  Built on the smallest LTE antenna platform available, the antenna is for use in small portable LTE devices such as mobile phones, wireless routers and wireless modems.  The antenna was designed to meet future demands for world phones with truly global roaming that also work seamlessly in LTE multiple-input, multiple-output (MIMO) networks while providing normal WCDMA, CDMA and GSM access. 

The adjustable single-element antenna requires only a single feed to cover all seven cellular operating bands with no market-specific versions needed.  It comes in an extremely compact size of 50.2 x 18.0 x 6.9 millimeters, which includes volume for speakers and other accessories within the antenna frame structure. 

Pulse’s LTE antenna is manufactured using Laser Direct Structuring (LDS) technology.  LDS enables finer tuning of the antenna during production by allowing for finer line width and spacing than any other 3D antenna manufacturing technology on the market.  3D shapes are needed to achieve ever smaller and thinner mobile devices.  They provide better RF performance by optimizing the space available for the antenna and permit more design freedom, especially in the case of the round shape. 

LTE provides the ability to deliver high data rates to a variety of consumer devices including Mobile Internet Devices (MIDs) and smartphones.  To achieve maximum data rate, the current LTE standard calls for MIMO antenna technology or using two separate antenna structures for multiple transmitting and receiving signals.  The Pulse LTE antenna has been characterized in 2x2 MIMO implementation.  The antenna configuration has two ports and diversity in all operating frequencies.  The required antenna volume is small and there is significantly lower correlation between antennas than seen in any other handset MIMO configurations.
