Embodiment 1

[0028] This embodiment proposes a terahertz full-duplex communication system for simultaneous transmission and reception. The system can simultaneously realize the dual functions of transmitting and receiving signals. The system includes a terahertz antenna, a terahertz radio frequency front end, an intermediate frequency circuit and a baseband circuit; the terahertz The RF front-end includes a terahertz bandpass filter, a terahertz quadrature-mode coupler, a terahertz subharmonic mixer, and a terahertz frequency multiplication link, and terahertz is realized in the same radio-frequency front-end through a terahertz quadrature-mode coupler The transmission and reception of signals, such as figure 1 shown.

[0029] In this embodiment, the terahertz radio frequency front-end part includes a terahertz bandpass filter, a terahertz orthogonal mode coupler (OMT), a first terahertz subharmonic mixer, a second terahertz subharmonic mixer frequency converter and terahertz frequency mu...

Embodiment 2

[0039] Based on the communication system of the above-mentioned embodiment 1, the terahertz orthogonal mode coupler (OMT) is further designed in this implementation, such as figure 2 As shown, the terahertz quadrature-mode coupler of this embodiment includes an input part (port 1), two output parts (port 2 and port 3), and a quadrature separation part (including a polarization separation structure and a transition structure). Two orthogonally polarized mode waves (horizontal polarization and vertical polarization) from port 1 pass through the polarization separation structure and transition structure, output vertically polarized waves from port 2, and output horizontally polarized waves from port 3, such as image 3 shown. Of course, reverse use is also possible, port 2 and port 3 are independent of each other. Port 1 is a square waveguide port with a size of 1.092mm×1.092mm; ports 2 and 3 are standard rectangular waveguide ports WR-4 with a size of 1.092mm×0.546mm.

Abstract

The invention discloses a terahertz synchronous receiving and transmitting full-duplex communication system. The system comprises a terahertz antenna, a terahertz radio frequency front end, an intermediate frequency circuit and a baseband circuit, the terahertz radio frequency front end comprises a terahertz band-pass filter, a terahertz orthogonal mode coupler, a terahertz sub-harmonic mixer anda terahertz frequency doubling link, and transmission and receiving of terahertz signals are achieved in the same radio frequency front end through the terahertz orthogonal mode coupler. On the basisof realizing the functions of transmitting and receiving terahertz signals at the same time, the transmitting channel and the receiving channel only adopt one antenna, so that the size of the front end of the communication system is greatly reduced, and the miniaturization of the system is utilized.

Description

technical field [0001] The invention relates to the technical field of terahertz communication, in particular to a terahertz full-duplex communication system for co-transmitting and transmitting. Background technique [0002] Terahertz waves refer to electromagnetic waves with a frequency between 100GHz and 10THz. This section of the electromagnetic spectrum is in a special position between the traditional electronics and photonics research frequency bands, and its research, development and utilization were relatively few in the past. With the rapid development of wireless communication, the existing spectrum resources have become increasingly scarce, and the development of new frequency bands for wireless communication has gradually become a consensus to solve this contradiction. However, there are a large number of undeveloped spectrum resources in the terahertz frequency band. The terahertz frequency is suitable as a new frequency band for future wireless communication. ...
