Abstract

The invention provides a patch-loaded broadband dual-polarized base station antenna. The patch-loaded broadband dual-polarized base station antenna comprises a first broadband balun structure, a second broadband balun structure, a metal patch and a reflecting plate. The first broadband balun structure and the second broadband balun structure are connected with the reflecting plate; the first broadband balun structure and the second broadband balun structure are perpendicular to the reflecting plate and are orthogonal to each other; and the metal patch is arranged above the first broadband balun structure and the second broadband balun structure. According to the invention, a novel resonance mode can be introduced through balun structure coupling excitation, so that the bandwidth of the antenna is expanded; the feed structure and the radiation unit are integrally designed, and the antenna bandwidth is expanded by loading patches, so that the design of the antenna can be simplified; while a wide working band is realized, the antenna has the characteristics of high gain, high isolation and low cross polarization, and can realize stable radiation pattern characteristics.

Description

technical field [0001] The invention relates to the technical field of base station antennas, in particular to a patch-loaded broadband dual-polarization base station antenna. Background technique [0002] With the continuous development of communication system technology and base station antennas, network coverage is becoming more and more perfect, and network quality is gradually improving. my country's base station antenna industry has also developed steadily. Now the base station antenna market is developing rapidly and has a bright future. [0003] With the advent of the fifth generation of mobile communication (5G), there are higher requirements for the bandwidth of the antenna, especially for the antenna to still have a stable pattern, gain and low cross-polarization performance under broadband. Undoubtedly, the design difficulty of the antenna is increased. [0004] For the size of the antenna, it is difficult to meet the requirement of miniaturization under the co...
