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...
