Abstract

A corner-truncated (linear and circular) antenna with a compressed reduced ground and parasitically loaded with a single unit of SRR was successfully designed, fabricated, tested, and investigated for 5G wireless communications. The truncated corner with a full ground shifted the narrow bandwidth and resonating frequency (5.10 GHz) from right to left (2.81 GHz). The ground-reduced length and compressed width enable a transition from a narrow band to a wide band, and the antenna is tuned to approximately 3.5 GHz. The antenna is parasitically loaded with an SRR that provides an additional resonating frequency within a wide bandwidth (2.82–5.21 GHz). The antenna achieves wideband with dual tuning frequencies within the band. The antenna has gains of 3.93 and 4.25 dBi at the tuned frequencies, respectively. The truncated ground enhances the antenna gain (3.33 to 4.25 dBi) and impedance bandwidth from narrow band (5.07–5.17 GHz) to wideband. The truncation of the corner and reduced ground length degrades the radiation efficiencies, while ground and substrate dimension (length and width) compression compensates for the reduced values of efficiencies. The proposed antenna is best suited for Wi-Fi 5 (IEEE 802.11ac), Wi-Fi 6 (IEEE 802.11ax), n48, n77, n78, and n79 applications. The antenna was measured and compared with the simulated results and radiation patterns. They were found in approximations, which helped confirm the antenna design and investigations.
