Adapter plate, adapter network and antenna

Abstract

The invention provides an adapter plate, an adapter network and an antenna. The adapter plate comprises a dielectric plate, a signal transmission line and a coplanar waveguide grounding section, the coplanar waveguide grounding section and the signal transmission line are arranged in a coplanar manner, and the coplanar waveguide grounding section is arranged at two sides of the signal transmission line; the coplanar waveguide grounding section covers the positions close to the two ends of the signal transmission line in the extending direction of the signal transmission line, and the two ends of the signal transmission line are each provided with a first welding point; signal transmission between circuit boards is realized by arranging the signal transmission line on a dielectric plate, losses in the signal transmission process can be reduced by the coplanar waveguide grounding section, the transmission mode is adopted to replace an existing cable and feed pin transmission mode, the losses in the transmission process are reduced, and electrical performance is improved; and in addition, the adapter plate is light in weight, small in size and high in consistency, facilitates arrangement of the circuit board and elements in the antenna, and facilitates miniaturization of the antenna.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an adapter board, an adapter network and an antenna. Background technique [0002] With the development of modern mobile communication technology, the communication system puts forward higher requirements for low cost and high performance. In modern 5G communication base stations, feeder networks, calibration networks, and filter networks are used. Calibration networks, filter networks, and RF connector boards usually use four-layer boards or multi-layer boards as link carriers. Calibration network, filter network and RF connector board use four-layer board or multi-layer board to achieve stable electrical indicators, while feed network and phase-shifting network use two-layer board. The purpose of using two-layer board is to reduce the cost of PCB . Due to the short replacement cycle, high power and large quantity of modern mobile communication base stations, it i...
