Title:
FEED STRUCTURE, MICROWAVE RADIO FREQUENCY DEVICE AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/037132
Kind Code:
A1
Abstract:
Provided are a feed structure, a microwave radio frequency device, and an antenna. The feed structure comprises: a reference electrode, a first substrate and a second substrate provided opposite each other, and a dielectric layer filled between the first substrate and the second substrate. The first substrate comprises: a first base, and an input electrode provided on one side of the first base close to the dielectric layer. The second substrate comprises: a second base, and a receiving electrode provided on one side of the second base close to the dielectric layer, wherein the orthographic projection of the receiving electrode on the first base at least partially overlaps the orthographic projection of the input electrode on the first base, so as to form a coupling structure. The output terminal of at least one of the input electrode and the receiving electrode is connected to a phase shift structure, so that a microwave signal transmitted by means of the first substrate and a microwave signal transmitted by means of the second substrate have different phases; and the input electrode, the receiving electrode and the phase shift structure all form a current loop with the reference electrode.
