Abstract

This paper proposes an asymmetric structure dual-polarized antenna based on a combination of a circular arc gap and a printed monopole of a dielectric integrated coaxial (SICL) resonant cavity. The dielectric integrated coaxial resonator cavity circular annular gap and printed monopole are both implemented by printed circuit technology, which are isolated from each other in the vertical direction to form two dual-polarized ports. The electromagnetic simulation and optimization of the designed dual-polarized antenna show that the voltage standing wave ratio of the two ports is less than 2 and the port isolation is greater than 20 dB within the working bandwidth. On the two polarization ports, the designed radiation gains of the dual-polarized antenna based on the SICL cavity ring gap and the printed monopole are about 6.3dB and 7.5dB, respectively, and the main radiation direction axis ratio is greater than 40dB. The dual-polarized antenna has a simple structure and low cost, and is suitable for applications such as dual-polarized radar and communication systems.
