DESIGN AND ANALYSIS OF RECONFIGURABLE ANTENNA WITHHYBRID RF MEMS SWITCH

This paper presents the design and simulation of the antenna with different RF MEMS switches for satellite applications. The proposed antenna offers low return loss and high VSWR. With a variety of reconfigurability in terms of gain, VSWR, radiation pattern, return loss the RF-MEMS switch has been commonly used in antenna design. A CPW feed line with central conductor width W = 3 mm and ground signal gap S= 0.3 mm is used. The performance analysis is done by using the HFSS tool. A circular patch antenna found return loss at 0.45dB, gain as 1dB and VSWR is 5. By integrating hybrid RF MEMS switches having excellent return loss at 32dB, gain as 5dB and VSWR is
