Abstract
This paper presents design and the performance analysis of capacitive shunt RF MEMS Switch. Here, the proposed Rf MEMS Switch shows the low pull-in voltage i.e 11.97 V and performed at 38 GHz with high isolation. To improve the performance of antenna characteristics microstrip feeding technique and co-planar-waveguide transmission line feeding are used in this design process. The impedance matching of 50Ω in the antenna is depends on the width of the feed line can be observed through simulated smith chart by using the Ansoft HFSS simulator. The micro strip patch antenna exhibits a Return loss is − 12.4264 dB and exhibits resonance at 38 GHz and the band width frequency from 37 to 39 GHz.After analyzing the performance of the antenna then the antenna is integrated with RF MEMS capacitive shunt switch through co-planar wave guide transmission feedline technique. By integrating with switch there is a frequency shift OF 1 GHz toward right from 38 GHz in antenna. The resonance is occurred at 39 GHz with bandwidth frequency between 38 and 40 GHz. The antenna exhibits return loss is − 27.2666 dB at operating frequency 39 GHz with RF MEMS switch and total gain of the antenna at 38 GHz with angle of ϕ = 90° is 5.6671 dB. Thus the performance of the antenna is increased by integrating with RF MEMS switch. These type of reconfigurable antennas are used in high frequency applications at frequency range of Ka-band and in wireless communication applications and satellite communication.
