Design of Dual Frequency Rectangular Patch Antenna Operating in Ku-Band

Abstract: This paper presents a microstrip fed rectangular patch antenna to operate at Ku-band at 12.33 GHz and 15.33 GHz with an operational bandwidths of 0.7 GHz (12 to 12.7 GHz) and 0.97 GHz (14.83 to 15.8 GHz). The antenna has been designed and simulated on an FR4 substrate with dielectric constant of 4.4 and thickness of 0.157 cm.This paper also presents the detail steps of designing and simulating the rectangular patch antenna in Ku-band.The design is analysed by Finite Element Method based HFSS Simulator Software (version 14.0) by which return loss,3D polar plot,Gain of the antenna are computed.The simulated results shows that the proposed antenna provides good performance in terms of return loss and radiation pattern for dual frequency applications.
