Kind Code:
A1
Abstract:
The invention relates the field of communications, and the embodiments of the invention provide a feed structure and an antenna radiation system having a compact structure. The feed structure comprises a first balun structure and a second balun structure. Each balun structure comprises at least a three-layer structure. The three-layer structure sequentially includes a first feeder line layer, a common signal ground layer, and a second feeder line layer. The common signal ground layer comprises two common signal grounds that are disposed at an interval. The first feeder line layer comprises a first feeder line. The second feeder line layer comprises a second feeder line. One feeder line in the first balun structure and one feeder line in the second balun structure form a first feed port. Another feeder line in the first balun structure and another feeder line in the second balun structure form a second feed port. Signal grounds are disposed at the bottom of the first balun structure and the bottom of the second balun structure. The embodiments of the invention are applied to a multi-frequency antenna array.
