Design and Analysis of Biquad Patch Antenna with Different Hard Substrates for UWB Applications

Abstract

An innovative double Biquad patch antenna was introduced. It consists of two quad patch together. good directivity was achieved due to the corner reflector effect used in this design. The radiating elements are of four square with the side length equal to 1/4 mid band wavelength. The theoretical beam width can be varied widely with the reflection plane size and shape. Vertical Polarization is achieved from the position of orientation of the biquad.Biquad patch was implemented in microstrip antenna with three hard substrates such as Arlon, Neltec, and Fr4, High directivity,good gain and low return loss was achieved, and the resonant frequency obtained is from 5-10GHz, which is suitable for UWB application and the simulation was performed using HFSS.
