Problems solved by technology

However, its metal structure leads to the unavoidable large size and heavy weight of the antenna.
In practical applications, dual-polarized antennas are the first choice for base station antennas, and there are still great difficulties in considering their bandwidth, isolation, cross-polarization, gain and other characteristics.

Abstract

The invention relates to a broadband dual-polarized mobile base station antenna unit equipped with metallic pillars and belongs to the technical field of mobile communication base station design and manufacture. The antenna unit successively comprises, from top to bottom, a feed structure, a dielectric slab, a butterfly-shaped radiation structure, short metallic pillars, a coaxial line, plastic support column, and a metallic reflecting plate. The feed structure and the butterfly-shaped radiation structure are arranged on the upper surface and the lower surface of the dielectric slab in the same placed direction, respectively. The short metallic pillars cling to the butterfly-shaped radiation structure. The butterfly-shaped radiation structure is fixed to the metallic reflecting plate through the four plastic support columns. The coaxial line passes through the metallic reflecting plate. The inner core of the coaxial line is connected with the feed structure and the outer core of the coaxial line is connected with the butterfly-shaped radiation structure. The antenna unit has characteristics of a broad band, high isolation, low cross polarization, compact structure, and low cost, complies with the development tendency of current base station antennas, and has good practical value.

Description

Technical field [0001] The invention belongs to the technical field of mobile communication base station antenna design and manufacturing, and relates to a wide-band dual-polarization mobile base station antenna unit loaded with a metal column. Background technique [0002] The base station antenna, as the core part of the mobile base station, establishes a radio transmission line between the base station and each mobile station in the service area, and its performance directly affects the quality of the entire communication system. As a new type of antenna, the principle of dual-polarization antennas is that two antennas with orthogonal polarization directions work in the transceiver duplex mode at the same time, which can effectively resist multipath fading, increase the capacity of the communication system, and reduce the number of antenna installations. Used in the design of base station antennas. In order to solve the current situation of multi-network, multi-operator co-si...
