Abstract

The invention provides a device and a method for mutual transition between a rectangular waveguide and a parallel plate waveguide. The device comprises the parallel plate waveguide and the rectangular waveguide, wherein a plurality of clearances which are central inclined clearances or longitudinal biased clearances are arranged on one wide edge of the rectangular waveguide; the parallel plate waveguide is in close contact with one side of the rectangular waveguide, which is provided with the clearances; and the parallel plate waveguide is positioned at the center of the rectangular waveguide. The device and the method provided by the invention have the advantages that the problem of mutual transition between the rectangular waveguide and the parallel plate waveguide is solved; the problem of feed of an antenna array of the parallel plate waveguide is solved and the defect of great loss in the prior art is overcome. When a plastic surface electroplating forming process is adopted, the device and the method have the advantages of low cost, light weight, simpleness in processing, easiness for large-batch production and the like.

Description

technical field [0001] The invention relates to the field of microwaves and antennas, in particular to the field of mutual transition between rectangular waveguides and parallel plate waveguides and the field of feeding power to parallel plate waveguide antenna arrays. Background technique [0002] Rectangular waveguide and parallel plate waveguide are two common microwave transmission lines. In a microwave transmission system, when connecting these two different types of microwave transmission lines together, microwave transition elements are needed to realize the conversion between transmission lines. In the antenna system, it is also necessary to feed power to the parallel plate waveguide antenna array. [0003] In the European patent "BROADBAND MICROSTRIP TO PARALLEL-PLATE-WAVEGUIDE TRANSITION" (application number: 99966071.5), a method and device for feeding power to a parallel plate waveguide are disclosed, but it has complex structure, large size, difficult realizatio...
