Abstract

The invention discloses a feed structure and a base station antenna. The base station antenna comprises a reflecting plate and at least one feed structure installed on the reflecting plate. The feed structure comprises a radiator, a feed balun and a feed panel. One end of the feed balun is connected to a radiator and the other end passes through the feed panel and is grounded. The end surface of the feed balun, which is grounded, is provided with at least one groove, and interrupted grounding is realized. During working, an excitation signal is converted and transmitted to the radiator by thefeed panel through the feed balun. In the invention, antenna radiation performance can be increased, an antenna cross polarization ratio can be improved, an antenna gain can be increased, base stationcoverage is improved and antenna electrical performance is optimized.

Description

technical field [0001] The invention relates to the field of mobile communication, and is applied to a base station antenna feed system, in particular to a feed structure and a base station antenna for improving antenna radiation performance and cross-polarization ratio of the antenna. Background technique [0002] As one of the most important components in the base station, the base station antenna is mainly responsible for converting the electrical signal of the communication equipment and the space radiated electromagnetic wave. Base station antennas can be divided into single-polarization and dual-polarization base station antennas according to the polarization mode. Compared with single-polarized antennas, dual-polarized antennas can shorten the space interval between antennas, and have the advantages of reduced call loss, reduced interference, and high service quality. [0003] Base station antennas are generally composed of radiating elements of the same structure to...
