Embodiment Construction

[0047] The specific implementation manner of the present invention will be further described below in conjunction with the drawings and embodiments. The following examples are only used to illustrate the present invention, but not to limit the scope of the present invention.

[0048] figure 1 It is a structural schematic diagram of the revolving door phase shifter of the present invention, figure 2 yes figure 1 Schematic cross-sectional view of the middle turnstile phase shifter along the MM' plane. As shown in the figure, the turnstile phase shifter is composed of two parts, which are circular polarizer 1 loaded with arc-shaped diaphragm and cross-shaped waveguide-circular polarizer 2. In the specific implementation process, the fixed cross-shaped The waveguide-circular polarizer 2 does not move, but the circular polarizer 1 loaded with an arc-shaped diaphragm can rotate arbitrarily around its own axis, and the rotation angle of the circular polarizer 1 loaded with an arc...

Abstract

The invention discloses a turnstile type phase shifter, and aims to provide a turnstile type phase shifter with a compact structure, a fast phase shifting speed, high precision and a large power capacity. The phase shifter comprises an arc diaphragm loaded circular polarizer and cross-shaped waveguide wire circular polarizer. The resonant cavity of the arc diaphragm loaded circular polarizer is aligned with the first circular waveguide of the cross-shaped waveguide wire circular polarizer. The arc diaphragm loaded circular polarizer consists of a coaxial waveguide, the resonant cavity, a balun structure, and metal diaphragms. The cross-shaped waveguide wire circular polarizer consists of a cross-shaped rectangular waveguide, a first circular waveguide, a second circular waveguide, a metal cylinder, and a metal hemisphere. The cross-shaped waveguide wire circular polarizer is a fixed one that does not move while the arc diaphragm loaded circular polarizer can rotate to its axis at any given angle that represents the phase shift of a TE10 mode. With the phase shifter of the invention, it is possible to achieve high mode conversion efficiency; with a compact structure, a good phase-shifting effect can be achieved at a high speed for the phase adjustment of a TE10 mode at will.

Description

technical field [0001] The invention relates to the field of high-power microwave devices, in particular to a turnstile phase shifter. Background technique [0002] High-power microwave (High-Power-Microwave, abbreviated as HPM) generally refers to strong electromagnetic radiation with a frequency between 300 MHz and 300 GHz and a peak power greater than 100 MW or an average power greater than 1 MW. There are various applications of high-power microwaves, mainly including: high-power pulse radar, which is used to accurately distinguish targets in a wide frequency band; high-energy particle radio-frequency accelerators, which are used in high-energy physics and nuclear physics research; Plasma heating and high-power microwave weapons and other fields. [0003] Microwave phase shifter is a common device in the field of microwave and millimeter wave technology. It has a wide range of applications in various fields such as radar systems, communication systems, and electronic co...
