Rectangular Patch Array Antenna with Liquid Crystal Substrate for Ka and Q Band Applications

This paper mainly deals with the design of Microstrip rectangular patch array antenna on liquid crystal substrate at 40GHz. The antenna parameters are simulated using commercial Ansoft HFSS software and the detailed explanation of performance evaluation is presented. A 4x4 rectangular patch array was designed on liquid crystal substrate material and their return loss, input impedance, gain and antenna parameters are studied and presented in this paper.
