Abstract

This paper presents the design of a wideband circularly polarized E-shaped patch antenna for 2.4-GHz wireless local area networks (WLAN) applications. The proposed antenna is a modified form of the conventional circularly polarized E-shaped patch antenna. By incorporating additional slots into the antenna patch, the impedance bandwidth and return loss of the circularly polarized antenna are improved by about 6.5% and 12 dB, respectively. Measurements of the fabricated antennas show good agreement with simulated results.
