Abstract

The invention provides a multi-frequency base station antenna. The multi-frequency base station antenna comprises a reflecting plate and a plurality of columns of radiation elements arranged on the front surface of the reflecting plate, wherein the columns where the radiation elements are located comprise nested columns and non-nested columns, and the nested columns and the non-nested columns arearranged at intervals; the nested column comprises high-frequency radiation elements and low-frequency radiation elements which are arranged at intervals; the non-nested column comprises a plurality of high-frequency radiation elements; metal strip-shaped boundaries perpendicular to the axis of the reflecting plate are arranged on the two sides of each high-frequency radiation element in the non-nested column; and the metal strip-shaped boundaries are arranged along the axis of the non-nested column. The radiation waveform of the high-frequency radiation element is smooth, the polarization gain is improved, and the miniaturization of the multi-frequency antenna is realized.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, in particular to a multi-frequency base station antenna. Background technique [0002] With the rapid development of mobile Internet services, the data traffic of mobile users has increased rapidly, which puts forward higher requirements for the system capacity and transmission rate of mobile communications. [0003] As the electromagnetic wave receiving and transmitting device at the front end of the mobile communication system, the base station antenna is an important hub for the connection between mobile users and base station equipment, and its working performance is very important. In practical applications, by developing multi-frequency multi-port antennas and increasing the number of antenna channels, the capacity of the communication system can be effectively improved and the signal coverage effect can be improved. [0004] For multi-frequency and multi-port antennas, in ord...
