A 5G Gong-shaped Circular-polarization Antenna

In this paper, 5G Gong-shaped circular polarization antenna has been proposed and designed using a Chinese “ 公 ”, which is to develop a circularly polarized (CP) artistic patch antenna for 5G communication system. The Chinese character “ 公 ” with a pronunciation of “gong” is printed on the top of a substrate to construct a radiation element, and the circular polarization of the antenna is realized by adjusting the position of the “gong”, and a L-shaped feeding probe is also used to enhance the bandwidth of the antenna. By utilizing a U-shaped metal box, the axial ratio bandwidth and gain are improved. By simulating and optimizing in the HFSS 2019, the results show that the Gong-shaped antenna has an axial ratio bandwidth of $2.47 \sim 2.68$ GHz and impedance bandwidth of $2.45 \sim 2.78$ GHz, which can cover the band of 5G communication ranging from 2.515GHz to 2.675GHz.
