Abstract
The invention provides a feeding structure, a microwave radio frequency device and an antenna, belonging to the technical field of communication. The feeding structure of the present invention includes: a reference electrode, a first substrate and a second substrate oppositely arranged, and a dielectric layer between the first substrate and the second substrate is filled; wherein, the first substrate includes : a first substrate, an input electrode arranged on a side of the first substrate close to the dielectric layer; the second substrate includes: a second substrate, a receiving electrode arranged on a side of the second substrate close to the dielectric layer electrode, and the orthographic projection of the receiving electrode and the input electrode on the first substrate at least partially overlaps to form a coupling structure; the output end of at least one of the input electrode and the receiving electrode is connected to a phase The phase shift structure is used to make the phase of the microwave signal transmitted through the first substrate and the microwave signal transmitted through the second substrate different; and the input electrode, the receiving electrode, and the phase shift structure all form a current loop with the reference electrode.
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...
