To achieve global connectivity between people, people, things, and things, satellite communications, especially low-orbit satellite communications, play a core role. China Star Network (SatNet) is a large-scale satellite internet constellation currently under construction in China. Tiantong Satellite is my country's first generation of independently controllable satellite mobile communications system, providing Chinese users with stable and reliable all-weather, all-day mobile communications services, supporting voice, short messaging, and data services. This effectively addresses the long-standing problem of ground communication network coverage in remote areas of my country, such as oceans, deserts, forests, and mountainous areas. It has achieved full coverage of the oceans and islands within my country's territory and territorial waters.

Therefore, satellite antennas that support StarNet and Tiantong can not only reduce the number of antennas but also reduce the size, weight and cost of the terminal. In view of this, we propose a dual-receive, dual-transmit antenna. Utility Model Content
