Adaptive Micro-Antenna on Silicon Substrate

Adaptive antenna technology represents the most advanced smart antenna approach to date. Using a variety of new signal-processing algorithms, the adaptive system takes advantage of its ability to effectively locate and track various types of signals to dynamically minimize interference and maximize intended signal reception. This paper presents the design and development of a micro-antenna for SoC, working at 43.763 GHz and controlled by independent MEMS based DMTL phase shifters which are low power in nature. We have also explored other required low power SoC devices which would also have the ability to reconfigure to the demands of our communication device. This in turn will enhance the desirability of our adaptive antenna for future low power mobile devices. The criteria for such a device must be its small size, a functionality that must make it possible to use over a wide variety of applications and similar fabrication techniques as with the rest of the SoC design. Our MEMS based design allows us to have all the communication and control circuitry on a single silicon substrate; enabling easy fabrication
