Problems solved by technology

Since the broadband antenna can radiate signals in the RF frequency band, the local oscillator frequency band, and the frequency bands between the two, if the generated harmonic components fall near the radio frequency band, the local oscillator frequency band, or between the two, dual frequency will occur. sub-radiation, resulting in a loss of part of the RF energy

Abstract

The invention provides a terahertz frequency mixing antenna and a quasi-optical frequency mixing module. The terahertz frequency mixing antenna comprises a first schottky diode, a second schottky diode, a planar antenna and a blocking condenser, wherein a negative pole of the first schottky diode is connected with a positive pole of the second schottky diode through the blocking condenser, and a positive pole of the first schottky diode is connected with a negative pole of the second schottky diode directly or through a resistance. The schottky diodes are arranged on radio frequency feed ports of the planar antenna, a radio frequency signal and a local oscillating signal are fed in a space coupling mode through the planar antenna, and an intermediate frequency signal is output after the frequency mixing of the schottky diodes and is output in a guided current mode from the outermost side of the planar antenna. The quasi-optical frequency mixing module comprises the terahertz frequency mixing antenna, a bias and intermediate frequency circuit and a planar transmission line. The terahertz frequency mixing antenna and the quasi-optical frequency mixing module are capable of being operated in a sub-harmonic frequency mixing mode or a fundamental wave frequency mixing mode, and being connected with a standard circuit port easily. Due to the fact that direct current bias is loaded on the frequency mixing antenna, requirements of local oscillating power is reduced.

Description

technical field [0001] The field relates to the technical field of terahertz wave detection, in particular to a terahertz frequency mixing antenna and a quasi-optical frequency mixing module. Background technique [0002] Terahertz is the last segment of the electromagnetic spectrum to be developed. The unique properties of terahertz radiation make terahertz imaging technology one of the current research hotspots. Terahertz detector is one of the key components of terahertz imaging, and its core is terahertz antenna and mixer. In order to realize the miniaturization of the detector, the antenna can be integrated with the mixer, that is, the frequency mixing antenna, also known as the terahertz mixing antenna. [0003] Terahertz mixing antenna is a device that combines antenna coupling and frequency conversion. It has the following characteristics: easy to process and implement, and can use semiconductor technology and optical technology with high processing precision if ne...
