Problems solved by technology

Functional devices in communication systems are also facing huge challenges, whether in system architecture, integration miniaturization, electromagnetic compatibility, or manufacturing costs.
Moreover, there are many limitations in the use of metamaterial microwave devices designed using metal resonance, such as high temperature environments.
If it is applied to the frequency selective surface of the radome, the high temperature friction in outer space will destroy the metal structure, so it loses its effect

Embodiment Construction

[0017] This embodiment provides a fully dielectric reflection dual-band polarization converter with a ship anchor structure, the structure of which is as follows figure 1 As shown, it includes a substrate and a polarization conversion mechanism on its upper surface. The substrate used in this embodiment is a metal reflector 5 . The polarization conversion mechanism is a three-dimensional anchor-type resonant unit composed of several single high-permittivity media, and its structure is distributed in two mutually perpendicular planes. The resonant unit includes a backbone structure 4 arranged diagonally along the substrate and branch structures distributed symmetrically at both ends.

[0018] Wherein, the branch structure is composed of a first branch 1 , a second branch 2 and a third branch 3 whose ends are connected to each other. The first branch and the third branch are distributed in parallel along the side of the substrate, and the tops are connected to the trunk struct...

Abstract

The invention relates to a full-medium reflection-type dual-band polarization converter having a boat anchor structure. The full-medium reflection-type dual-band polarization converter having the boatanchor structure comprises a substrate and a polarization conversion mechanism arranged on the upper surface thereof, wherein the polarization conversion mechanism is a three-dimensional boat anchor-type resonance unit consisting of a plurality of single high-dielectric constant media; the resonance unit comprises a trunk structure (4) arranged along the diagonal of the substrate and branch structures symmetrically distributed at the two ends thereof; a plane formed by the trunk structure and first and third branches is vertical to a plane formed by the trunk structure and second branches. Dual-band polarization conversion working in an X band can be achieved through the adoption of the single and simple full-medium boat anchor structure; two polarization conversion frequency points can be separately regulated; the full-medium reflection-type dual-band polarization converter adopting the boat anchor structure is simple in design and easy to implement.

Description

technical field [0001] The invention relates to a polarization converter, in particular to a full-dielectric reflection dual-band polarization converter with an anchor structure, belonging to the technical fields of electronic communication and microwave devices. Background technique [0002] With the development of communication and information technology, people put forward more stringent requirements for microwave components and functional devices in communication systems, and the manipulation of electromagnetic waves must meet different needs. Functional devices in communication systems are also facing huge challenges, whether in system architecture, integration miniaturization, electromagnetic compatibility, or manufacturing costs. Moreover, there are many limitations in the use of metamaterial microwave devices designed with metal resonance, such as high temperature environments. If it is applied to the frequency selective surface of the radome, the high temperature f...
