Gauging Trowel Shaped Patch With a Novel DGS for 64 GHz Application

Abstract

This artefact provides the design of a novel patch including both semi-circular and triangular shape. The diameter of the semi-circular patch and the base of the triangular patch has been taken same as that of the value of twice the wavelength calculated from the design frequency. The projected patch has been designed on a substrate including a dielectric material FR4 epoxy that is having a dielectric constant 4.4. The focus has been made on the S11 (<-10 dB) Vs frequency plot from which the resonant frequency and return loss can be determined. The implementation of ring DGS shift the resonant frequency to the value at which the antenna is made to operate. Apart from S-Parameter, the standing wave ratio measured in terms of voltage, directivity, antenna gain, surface current distribution has been determined with the help of simulation that is done by HFSS software. 64 GHz has been chosen as the frequency of operation that is reserved for intelligent transport system (ITS).This antenna can also be used for FWS as it is having a broadband characteristic.
