N2 - Satellite communication is an indispensable part of modern communication. In recent years, with the rapid rise of 5G-Technology, satellite communication is developing towards high frequency, multi-polarization, wide spectrum and multi-mode, which requires the antenna to have the characteristics of low profile, wide-band, dual-polarization and high gain. The traditional waveguide dual-polarization antenna has some disadvantages, such as narrow bandwidth of VSWR, poor cross-polarization and port-isolation and so on. In this paper, a novel dual polarization waveguide slot antenna is proposed, which has the advantages of large bandwidth, high efficiency, low cross-polarization, high port-isolation, low profile and simple structure. At the same time, a 2 × 2 array in Ka band is designed. The simulation results show that in the frequency band range of 16%, the standing-wave ratio of the two polarities is less than 2, the radiation efficiency is more than 800%, the cross-polarization is less than -25dB, and the port isolation is more than 25dB.
