Abstract

The invention provides a feed network and an antenna feed system. The antenna feed system comprises a feed plate, arrays and a feed network, wherein the feed network comprises array matching lines, sub-array matching lines and debugging lines, the line width of the array matching line is equal to the line width of the sub-array matching line, the line width of the debugging line can be unequal tothe line width of the array matching line and the line width of the sub-array matching line, the array matching line is used for being connected with the array, the adjacent arrays are connected through the sub-array matching line, the debugging lines are arranged on the sub-array matching lines, and the input impedance of a feeder line is adjusted and matched through the length and the width of the debugging line. According to the design method that the line width of the array matching line and the line width of the sub-array matching line are equal, the design of a matching circuit is greatly simplified, the number of sections and the number of bends of the matching lines are reduced, and losses are reduced; and high consistency and reliability can be achieved when an electroplating process is adopted for machining while the whole circuit diagram is attractive and simple.

Description

technical field [0001] The present invention relates to the technical field of 5G wireless communication base stations, in particular to a feeding network and an antenna feeding system. Background technique [0002] The feed network is an important component of the base station antenna. It connects the antenna port and the array element to form a path for radio frequency signal transmission, and realizes functions such as impedance matching and amplitude phase distribution. [0003] The feed network is closely related to the performance of the antenna array, and directly affects the parameters such as the standing wave ratio, radiation efficiency, beam pointing, sidelobe level, and zero point of the antenna array. In the feed network design of the base station antenna network, focus on the impedance matching, insertion loss, amplitude and phase distribution and other characteristics of the feed network to reduce antenna array loss, improve radiation efficiency, increase ante...
