A terahertz twisted waveguide based on diaphragm polarization converter and its realization method

Abstract

A terahertz twisted waveguide based on a diaphragm polarization converter, including a first straight waveguide, a polarization converter, a filling medium, a choke slot, a short circuit, a second straight waveguide, a coupling probe and a circular waveguide; the first The straight waveguide is connected to one port of the polarization converter, the other port of the polarization converter is connected to one port of the circular waveguide, a short circuit is built on the other port of the circular waveguide, and the second straight waveguide is connected to the short circuit through a coupling probe. Connection; the circular waveguide is disconnected, a choke slot is constructed at the disconnection, and the filling medium is filled in the choke slot. The invention also provides a realization method of the terahertz twisted waveguide. The present invention can realize arbitrary angle twisting, effectively solves the problems of difficult interconnection of non-parallel structures in existing terahertz systems, and heavy loads of terahertz communication or radar mechanisms, and enhances the practicability of terahertz communication or radar systems.

Description

technical field [0001] The invention relates to a terahertz frequency band radio frequency passive circuit, in particular to a terahertz twisted waveguide based on a diaphragm polarization converter and a realization method thereof, belonging to the technical field of terahertz radio frequency. Background technique [0002] In space communication, due to the high-speed relative movement of the spacecraft, the space link communication time is short, and the surge of space services requires a very large amount of data transmission. Due to the high transmission rate, terahertz communication can transmit a large amount of information in a short time, which is very suitable for space communication. [0003] In practical applications, the radio frequency circuits of terahertz communication or radar systems are very complex, and there is no coaxial flexible waveguide structure, and the expansion form of the system topology is greatly restricted. However, in actual system integrati...
