Abstract The application of Micro Electro Mechnical Switch

(ESAs) provides the potential for significantly reducing the volume, weight, cost, and power consumption of antennas for both radar and communications systems. This paper addresses the current and projected status of Radio Frequency (RF) MEMS technology and assesses the potential benefits of MEMS phase shifters for application in ESA antennas. The assessment of potential applications is accomplished by comparing the systems impact of this technology to conventional technologies
