SkyCross Unveils iMAT Single Antenna

SkyCross unveiled its Isolated Mode Antenna Technology (iMAT) single-antenna approach providing MIMO capabilities.


SKyCross said its revolutionary antenna design will enable designers of handsets, PC cards, USB dongles, personal navigation and other wireless electronics to offer diversity or multiple input, multiple output (MIMO) communications, even in applications where such implementation has been considered impossible due to space constraints inside mobile devices. Traditionally, MIMO leverages multiple antennas at both the radio transmitter and receiver to improve communication performance. Next-generation protocols, such as HSxPA, WiMAX, 802.11x, and LTE, all of which require diversity or MIMO.


The single-antenna solution from SkyCross eliminates the need to configure multiple antennas and reduces the number of parts required to build a device. The company said its iMAT enables a single device antenna to perform like multiple antennas through the use of multiple feed points. Each feed accesses the antenna as if it consisted of multiple antennas, each with high isolation, low correlation, and high per-feed antenna efficiency. The multiple radiation patterns produced by an iMAT antenna have low correlation so they cover different spatial regions to achieve pattern diversity and signal independence. This makes the way the device is "pointed" with respect to towers and base units less crucial.http://www.skycross.com
