Abstract

The invention provides a terahertz frequency band spiral mixing antenna, a terahertz frequency band spiral sub-harmonic mixing antenna and a terahertz frequency band spiral sub-harmonic inclinable mixing antenna. The mixing antennas comprise spiral antennas and schottky diodes, wherein each schottky diode comprises a schottky contact electrode, an ohmic contact electrode and an electroplate lead, and the schttky diodes are arranged at the radio frequency feed port positions of the spiral antennas. The schottky diodes and the spiral antennas are manufactured in the semiconductor technology, and the schottky contact diodes and the spiral antennas use the same half of insulating gallium arsenide layer as the substrate. The mixing antennas can achieve space coupling and detection of terahertz frequency band circular polarization signals, simultaneously have the advantages of being small in size, light in weight and consistence in height and is suitable for large-scale imaging arrays.

Description

technical field [0001] This field relates to the technical field of terahertz wave detection, and in particular relates to terahertz frequency band helical mixing antennas, terahertz frequency band helical subharmonic mixing antennas and terahertz frequency band helical subharmonic biasable mixing antennas. Background technique [0002] Terahertz is the last segment of the electromagnetic spectrum to be exploited. The unique properties of terahertz radiation make terahertz imaging technology one of the research hotspots today. 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 and easily form a large-scale array, the antenna can be integrated with the mixer, that is, the mixing antenna; it can be widely used in imaging, radio astronomy, communication and other fields. Especially in the field of focal plane imaging, the frequency mixing antenna is a low-co...
