Design of a High Gain Antenna for WiFi/6E Application

Technical requirements in wireless communications need antennas of different sizes, shapes, radiation patterns and bandwidth. Microstrip patch antenna plays vital role in wireless communication in WiFi/6E applications. This research study is based on designing and simulation of the triangular patch microstrip antenna with Defected Ground Structure (DGS) using coaxial feed. The objective of this work is to be comparing the various substrates which include Roger RT duroid 5880, FR4 and Teflon. In this work, the impact of Defected Ground Structure (DGS) enhanced a great amount of gain and radiation pattern. By evaluating the performance of various substrates, it is recommended that using Teflon substrate it is useful for Wi-Fi 6E applications with the frequency band of 6.6GHz. The enhancement of parameters such as Gain 9.8dB, S11 -17.8dB, VSWR 1.29 and BW 0.8GHz are observed for Teflon substrate compared with the other two such as rogers RT duroid 5880tm and FR4 substrate. Good radiation pattern and frequency are added advantages observed. The simulation of Triangular patch DGS antenna is carried out in the High Frequency Signal Simulator software (HFSS) platform.
