Embodiment Construction

[0019] Structural principle of the present invention and working principle are specifically described below in conjunction with accompanying drawing:

[0020] The invention consists of a rectangular waveguide 1, a partition board 2, N phase shift boards 3 and N compensation boards 4. The rectangular waveguide TM11 mode microwave generated by the upstream devices such as strip electron beam microwave source is injected into the rectangular waveguide 1, and then the partition board 2, the phase shift board 3 and the compensation board 4 work together to carry out the rectangular waveguide TM11-TE10 Mode conversion.

[0021] The rectangular waveguide 1 is the main part of the present invention. Its cross-sectional width is a and its height is b. A is equal to the cross-sectional width of the output port of the upstream device (such as a strip electron beam microwave source) connected to this device, and b is equal to the upstream device (such as a strip electron beam source) con...

Abstract

The invention discloses a high-power microwave rectangular waveguide TM11-TE10 mode converter. The purpose is to provide a mode converter for directly converting rectangular waveguide TM11 mode microwave into rectangular waveguide TE10 mode microwave. The high-power TM11-TE10 microwave mode converter is composed of rectangular waveguide, a separation inserting plate, N phase shift inserting plates and N compensation inserting plates. The separating inserting plate is a metal plate with a wedge structure, and is fixed at the vertical middle position of the short side of the rectangular waveguide along the axial direction in an inserting slot manner and parallel to the long side of the rectangular waveguide; the phase shift inserting plates are vertical to the long side of the rectangular waveguide and uniformly fixed to the upper surface of the separating inserting plate, and the compensation inserting plates are vertical to the long side of the rectangular waveguide and uniformly fixed to the lower surface of the separating inserting plate. According to the high-power TM11-TE10 microwave mode converter, mode conversion can be achieved, no rectangular-circular transformation and other transition structures are arranged, structure is simple, processing cost is low, structure is compact, conversion efficiency is high and transmission band is wide.

Description

technical field [0001] The invention belongs to the field of microwave technology, and relates to a high-power TM11-TE10 microwave mode converter in a rectangular waveguide. Background technique [0002] In the field of microwave technology, it is an important research direction to use microwave mode converters to convert microwave modes that are difficult to radiate or directly apply (such as particle acceleration) into microwave modes that are convenient for antenna radiation or application. A well-designed microwave mode converter can connect the microwave source with its downstream microwave devices (such as radiation antennas) without designing a dedicated downstream microwave device for a specific microwave source, which enhances the modularity of the microwave system and improves the reliability of the microwave system. The design and debugging efficiency of microwave system has important research and application value in the fields of microwave generation, transmissi...
