DIRECTIONAL COUPLER FOR USE IN MULTI-BEAM ANTENNA FEED NETWORK

WIPO Patent Application WO/2021/077639

A1

The present invention is suitable for use in the technical field of communication devices, and provides a directional coupler for use in a multi-beam antenna feed network, comprising a first microstrip line structure, a second microstrip line structure, and a middle layer dielectric substrate, the first microstrip line structure, the middle layer dielectric substrate, and the second microstrip line structure being pressed and fixed together in sequence, a first coupling line of the first microstrip line structure being arranged at the top layer of the middle layer dielectric substrate, and a second coupling line of the second microstrip line structure being arranged at the bottom layer of the middle layer dielectric substrate. Thus, the present invention can implement 90 degree phase shift, reducing standing waves to achieve good transmission performance, and being well-suited to use in a multi-beam feed network.
