Abstract

The invention discloses a pointed bent rectangular waveguide based on a hyper-transport gap membrane. The waveguide is used for solving the technical problems that in the prior art, a waveguide structure is complex and the size is large. The pointed bent rectangular waveguide comprises a pointed bent rectangular waveguide body and the hyper-transport gap membrane. An H-face bent waveguide is adopted as the pointed bent rectangular waveguide body and is formed by splicing two symmetric waveguide structures, the hyper-transport gap membrane is loaded at the splicing position, a connection flange is arranged at one end of each waveguide structure, an inclined angle is formed between the plane where each connection flange is located and the cross section of the waveguide body, and the plane is inclined in the narrow-side direction of the cross section of the waveguide body; open gap structures in different modes are arranged in the center of the hyper-transport gap membrane, C-type single-frequency resonance rings or C-type multi-frequency resonance rings are adopted as the open gap structures, the openings face towards the wide side of the hyper-transport gap membrane, and non-reflection transmission of single-frequency or multi-frequency in-band electromagnetic waves can be achieved. The rectangular waveguide achieves non-reflection transmission of electromagnetic waves in the rectangular waveguide bent by any angle, and has the advantages of being simple in structure and small in size.

Description

technical field [0001] The invention belongs to the field of microwave technology, and relates to a sharply bent rectangular waveguide without reflection transmission, and specifically designs a sharply bent rectangular waveguide based on a supertransmission slit diaphragm, which can be used for wireless transmission of electromagnetic waves in a rectangular waveguide bent at any angle. reflection transmission. technical background [0002] Waveguide is an important part of microwave transmission devices. As a structure for directional guiding electromagnetic waves, common waveguide structures include parallel slab waveguides, rectangular waveguides, circular waveguides, and optical fibers. Rectangular waveguide is a regular metal waveguide with a rectangular cross-section filled with air. It has simple structure, low loss and large power capacity. It is one of the most commonly used transmission systems in microwave technology. For curved transmission, it is often necessar...
