Side-Edge Dual-Band Antenna for 5G and Wi-Fi 6 Applications

Abstract

This work presents a circularly polarized side-edge microstrip antenna for (5G) smartphone and Wi-Fi 6 applications. The designed antenna consists of several microstrip lines arranged in a way to produce dual operating bands, in the (5.32 – 5.52) GHz band and (6.15 – 6.36) GHz band with a percentage bandwidth of 3.69 % and 3.36 % respectively corresponds to 200 MHz and 210 MHz bandwidth for the two bands. The proposed single-element antenna is placed on the top portion of the FR-4 substrate side edge frame and fed by a coaxial SMA connector. The achieved results have exhibited reasonable antenna characteristics in terms of investigated reflection, gain, efficiency, radiation pattern, and impedance matching for the two resonating bands.
