Abstract
A circularly polarized wideband H-slot compact patch antenna for 5G applicational implements is proposed. The structure adopts a three-layer architecture with a perfect electric conductor (PEC) copper foil radiation patch on top, Rogers RT5880 dielectric material in between and copper foil grounding plate. Theoretical analysis is conducted on the characteristics, working principles, and microstrip patch antenna parameters to design a wideband H-slot compact structure to achieve high performance. Simulation and measurement analysis are conducted with antenna modeling and optimization on the essential performance parameters. The proposed patch antenna is circularly polarized at the resonant 2.4 GHz frequency in the operational domain of 2.2–2.6 GHz. The return loss of the target frequency band is <–10 dB, the VSWR is close to 1, the gain is >5 dB, and the sidelobe level is –19.2 dB with a radiation efficiency of 81.6%. The applicability of the proposed antenna in the 5 GHz/sub-6 GHz frequency band is suitable for broad spatial coverage, and is integrable with massive multi-input multi-output (MIMO) and other technologies to promote intelligent antenna evolutions.
