The invention provides a feed structure, a microwave radio frequency device and an antenna, and belongs to the technical field of communication. The feed structure comprises a reference electrode, a first substrate and a second substrate which are oppositely arranged, and a dielectric layer, and the space between the first substrate and the second substrate is filled with the dielectric layer; thefirst substrate comprises a first substrate and an input electrode arranged on one side, close to the dielectric layer, of the first substrate; the second substrate comprises a second substrate and areceiving electrode arranged on the side, close to the dielectric layer, of the second substrate, and the orthographic projections of the receiving electrode and the input electrode on the first substrate are at least partially overlapped to form a coupling structure; the output end of at least one of the input electrode and the receiving electrode is connected with a phase shift structure, so that the phases of microwave signals transmitted by the first substrate and microwave signals transmitted by the second substrate are different; and the input electrode, the receiving electrode, the phase shift structure and the reference electrode form a current loop.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a feeding structure, a microwave radio frequency device and an antenna. Background technique [0002] A phase shifter is a device that adjusts the phase of electromagnetic waves, and is widely used in various communication systems, such as satellite communication, phased array radar, remote sensing and telemetry, etc. Dielectric tunable phase shifter is a device that realizes the phase shift effect by controlling the dielectric constant of the dielectric layer. The traditional dielectric tunable phase shifter uses a single-wire transmission structure to achieve a phase shift effect by adjusting the signal phase velocity, but the problem with this design method is that the loss is relatively large and the degree of phase shift within a unit loss is relatively low. Contents of the invention [0003] The present invention aims to solve at least one of the techni...
