Embodiment Construction

[0016] Please also see Figure 4~Figure 7 , which is a schematic diagram of the structure of the quadrature-mode converter of the present invention. The orthogonal mode converter includes a body 1 and a cover plate 2 .

[0017] The body 1 is provided with a groove 3 and a stepped waveguide group 4 , the front end of the groove 3 is located at the edge of the body 1 to form a common port 31 , and the stepped waveguide group 4 is connected to the end of the groove 3 . The groove 3 is used as a common channel for signal transmission. The cross section of the groove 3 is square or circular, in this embodiment it is square. The stepped waveguide group 4 includes a plurality of stepped steps, and the number of the steps depends on the wavelength band that needs to propagate the signal. In this embodiment, the stepped waveguide group 4 sequentially includes a first step, a second step, a third step and a fourth step from the connection with the end of the groove 3, wherein, in thi...

Abstract

The invention relates to an orthogonal mode converter which comprises a body and a cover body, wherein the body and the cover body are mutually buckled. The body is provided with a groove, a step waveguide group and a coupling window. A public port is formed on the front end of the groove on the edge of the body. The step waveguide group is connected with the tail end of the groove. The step waveguide group successively comprises a first step, a second step,..., and a nth step from the joint with the tail end of the groove. The coupling window stretches across the tail end of the groove and at least the first step of the step waveguide group, goes down and runs through the bottom of the body. The cover body comprises a feeding hole, wherein the feeding hole directly faces at least the nth step of the step waveguide group. The orthogonal mode converter provided by the invention has the advantage of simple and compact structure and is suitable for mass production.

Description

technical field [0001] The invention relates to a microwave passive device, in particular to a microwave frequency band orthogonal mode converter. Background technique [0002] Microwave communication is one of the most commonly used wireless communication methods in the world, and it is widely used in data transmission, radio and television transmission, satellite communication, mobile communication and other fields. Orthogonal mode converter is an outdoor three-port network device for wireless transmission products, and it is a device that realizes duplex transmission (that is, separation and synthesis) of orthogonally polarized signals in the feed system. The orthogonal mode converter connects the outdoor dual-polarized antenna and two outdoor units (ODU), that is, the two integrated transceiver channels share one antenna through the orthogonal mode converter, which has the function of polarization separation. The main task of the quadrature-mode converter is to identify...
