Abstract

This research paper introduces a novel compact Circularly Polarized (CP) antenna tailored for 5G Wireless Local Area Network (WLAN) and X-band applications. The antenna design includes a circular patch, minimized ground, and a superstrate. Four V-shaped slits are embedded along the boundary of the circular patch, strategically positioned to generate circular polarization operating across multiple frequency bands. The antenna resonates in the ranges between 4.9 GHz and 5.6 GHz, 7.74 GHz and 8 GHz, and 10.9 GHz and 11.2 GHz. The design's effectiveness is verified through a compact antenna with dimensions of 0.636 λ0 × 0.636 λ0 × 0.21 λ0 . The results demonstrate 10-dB impedance bandwidths of 13.2%, 3.16%, and 2.7% for 4.9-5.6 GHz, 7.74-8 GHz, and 10.9-11.2 GHz, respectively. In addition, the findings revealed gains of 8 dBi, 6.89 dBi, and 8 dBi at resonant frequencies of 5.3 GHz, 7.9 GHz, and 11.1 GHz, respectively. With a radiation efficiency exceeding 97% across all resonant frequencies, the addition of a superstrate enhances gain by 3 dBi. Comparison between measured and simulated results confirms the accuracy of the proposed design. The triple-band CP compact antenna, augmented by a superstrate, showcases promising characteristics for 5G WLAN and X-band applications.
