Abstract

The invention relates to a dual-polarization CTS (Continuous Transverse Stub) beam scanning antenna array. The dual-polarization CTS beam scanning antenna array comprises two orthogonal waveguide power distribution feed structures and a dual-polarization CTS antenna array, wherein the waveguide power distribution structures are connected to the side surface of the CTS antenna array and are used for generating a plane wave; the dual-polarization CTS antenna array achieves H-side scanning along with frequency change. The antenna array achieves H-side beam scanning through the change of the frequency at a port, and can achieve beam scanning of -22 degrees to 9 degrees in the change range of 5.1.6-12.8GHz.

Description

technical field [0001] The invention relates to the field of beam scanning antennas, in particular to a dual-polarization CTS beam scanning antenna array for realizing beam scanning of dual-polarization antennas. Background technique [0002] With the development of wireless communication technology, there is an increasing demand for antennas to perform high-speed communication anytime and anywhere on mobile carriers, and broadband beam scanning antenna arrays have received extensive attention. The beam scanning antenna has the performance of high gain, high directivity, and controllable beam pointing. By changing the working mode, working state, working frequency or antenna posture of the antenna, the maximum radiation direction of the antenna can be changed, thereby realizing beam scanning. At present, in terms of mobile communication networks, the use of this high-gain antenna technology with variable radiation direction can meet the high-speed communication needs of use...
