Multi-system and multi-port base station antenna common reflection board

The invention provides a multi-system and multi-port base station antenna common reflection board, which comprises a main TD-LTE system reflection board body, a main GSM and DCS system reflection board body and corresponding radiation elements, wherein the main TD-LTE system reflection board body and the main GSM and DCS system reflection board body are arranged from top to bottom; the middle parts of the main TD-LTE system reflection board body and the main GSM and DCS system reflection board body are connected with each other through a connecting bend; the height and the bending angle can be adjusted according to different requirements; four columns of antenna radiation bodies are placed on the main TD-LTE system reflection board body and are partitioned by column baffles; the side edges are located at two sides of a main reflection backboard body; two columns of antenna radiation elements are placed on the main GSM and DCS system reflection board body; and a coaxial design scheme is adopted by GSM and DCS system radiation elements. The multi-system and multi-port base station antenna common reflection board is simple in structure and low in cost, has an obvious improvement effect on wave beam distortion caused by signal coupling between different systems, can independently adjust the distance from the antenna radiation body to an antenna housing, flexibly changes the radiation property of an antenna and avoids mutual coupling generated by different systems in the same plane.
