[0042] The present invention designs a specific cavity-backed dual-polarization antenna system device based on a medium-integrated coaxial cable, and uses full-wave electromagnetic simulation software to simulate the performance of the antenna array. The simulation experiment results verify the proposed method based on Feasibility and effectiveness of a cavity-backed dual-polarized antenna device with a dielectric-integrated coaxial cable.
[0043] The simulation results of the voltage standing wave ratio (VSWR) of port 1 and port 2 of the dual-polarized antenna designed by the present invention are respectively as follows Figure 7 with Figure 8 shown. The isolation between port 1 and port 2 is as Figure 9 shown. Within the working bandwidth, the voltage standing wave ratio of port 1 and port 2 is about 2, and the port isolation is greater than 20dB.
[0044] At the center at the frequency, the simulation results of the radiation pattern characteristics of the dual-pola...
