Novel plane wave magic T

Abstract

The invention discloses a novel plane wave magic T. The magic T comprises a common port, an H-plane wave guide common port and two branch wave guide ports, and an E-plane wave guide common port. The H-place wave guide common port and the centers of two branch wave guide ports are in a same plane. The cavity body connection area between the H-plane wave guide and the E-plane wave guide and two branch wave guides protrudes out, and the width of the protruded area is identical with the width of the H-plane wave guide. The connection area between the protruded area and the E-plane wave guide has steps. The connection area between the protruded area and the H-plane wave guide has steps. The section of connection area between the H-plane wave guide and E-plane wave guide has steps corresponding to the protruded area has steps. The magic T lowers the height of the magic T and has the advantages of having wide working band, good performance, consistency in both amplitude and phase, being simple in structure that the whole product is assembled with only two fully machined components, having no necessity to install additional components, having easily guaranteed allowable errors, high production efficiency and low production cost.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and in particular relates to a novel planar waveguide magic T used in systems such as wireless communication, radar electronic warfare equipment and weapon guidance equipment. Background technique [0002] The waveguide magic T is a power distribution passive device, because of its large power capacity, and simple structure, it is easy to manufacture. It is widely used in radar system equipment, guidance system equipment, microwave communication equipment and microwave test system. It is often used as components such as power distribution, power synthesis, power deployment, and differential network. [0003] Ordinary waveguide magic T has two disadvantages: 1. The height direction is relatively high, which will make the volume and weight of the whole system relatively large; 2. The two common waveguide ports are perpendicular to each other and are not on the same plane, which is...
