Integration of V-Band and W-Band antennas with SPDT switch on organic substrates

This paper presents, for the first time, the integration of V-Band and W-Band antennas with SPDT switch on organic Liquid Crystal Polymer (LCP) substrate. A wideband chip to package wire-bond transition was designed so that the insertion loss is minimized. The antennas were designed and optimized for frequency operation at 57 and 80 GHz with a gain of 10.5 and 9.5 dBi. The gain, S₁₁, E-plane and H-plane Co- and Cross-polarization measurements were conducted and successfully demonstrated a passive antenna gain of 10.08 dBi from 54-61 GHz for V-Band antenna with minimal deviation of 1.2 dB in the gain. Simulation results show gain of around 9.44 dBi from 77-85 GHz for W-band Antenna. Return loss also demonstrates 6 GHz and 8 GHz of 10 dB bandwidth (10% B.W) for V-Band and W-Band antennas respectively.
