Circularly Polarized Gap-Coupled Designs of Modified Square Microstrip Antennas for WLAN and Bluetooth Applications
By
Progress In Electromagnetics Research C, Vol. 138, 233-246, 2023
Abstract
Circularly polarized gap-coupled designs of corner truncated square microstrip antenna in 2400 MHz frequency spectrum are presented. The gap-coupled design on thinner substrate (~0.036λg) yields axial ratio bandwidth of 113 MHz (4.697%) whereas that on thicker substrate (~0.13λg) yields axial ratio bandwidth of 471 MHz (19.24%). Both the designs exhibit broadside radiation pattern with a peak gain above 7 dBi, thus satisfying the requirements of WLAN and Bluetooth applications. Simulated results have been experimentally verified, which show close agreement.
