Simulation study and optimal design of a new microstrip quasi-Yagi antenna for WiFi frequency band applications

This paper proposes a new microstrip quasi-Vagi antenna for WiFi band applications. The antenna structure employs an E-type reflector as well as 8 split-ring resonators, which makes the quasi-Vagi antenna with high gain and wide bandwidth to meet the requirements of wireless communication. Ansys simulation is used to model and analyze the gain, return loss and radiation direction characteristics of the antenna. Finally, the new microstrip quasi-Yagi is obtained, which has the largest gain of 7.28dB and can work at 2.32-2.66GHz with a relative bandwidth of 14%, covering the WiFi band. The antenna has a simple structure, easy to use, low cost, is powerful, and has good practical application value in projects with a large demand for antenna directional gain.
