Abstract

The invention discloses a wide-angle scanning dual-polarization dipole antenna, and belongs to the technical field of antennas. The wide-angle scanning dual-polarization dipole antenna comprises a first metal arm, an antenna support column, a second metal arm and a feed balun, wherein the first metal arm is located at the top of the antenna, and is used for improving the impedance fluctuation of the antenna during large-angle scanning; and the feed balun is located at the bottom of the antenna and is used for converting the unbalanced feed input by a coaxial line into a balanced feed. According to the antenna, the impedance matching during large-angle scanning of the antenna is greatly improved, and the antenna wide-angle scanning performance is effectively improved; meanwhile, the antennahas high cross polarization performance; and finally, due to the fact that both the metal dipole arm and the top metal arm adopt longitudinal blade-shaped bending structures, the cross section is small, snow and rain are not prone to being accumulated, the influence of accumulated snow and accumulated rain and the like on the performance and the service life of the antenna is greatly reduced, andthe antenna can be well suitable for severe weather conditions such as strong rainfall, strong snowfall and the like.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a wide-angle scanning dual-polarization dipole antenna. Background technique [0002] Antenna is one of the most important components of systems such as wireless broadcasting, wireless communication and wireless detection, and its structure and characteristics determine the working performance of the entire system to a large extent. Due to its excellent beam scanning and beam forming capabilities, phased array antennas have become an important development direction of modern antennas. Radar, communication and other systems often require phased array antennas to have characteristics such as wide operating frequency band, large scanning angle, and low return loss; antennas in some special applications often need to have strong environmental adaptability to adapt to harsh environments. working conditions. [0003] Dual-polarized antennas consist of two antennas with mutually orth...
