US 2020/0049620 A1 · TERAHERTZ ANTENNA BASED ON MUTI-FREQUENCY TRANSMISSION SWITCHING AND SPECTRAL DETECTION DEVICE THEREOF

Abstract

The present application relates to a terahertz transmitting antenna including a microstrip feed line, a substrate, at least two antenna switches, at least one conducting plate, an insulating layer and at least two antenna patches. The terahertz transmitting antenna is provided with at least two antenna switches and at least two corresponding antenna patches, which substantially increases a transmitting bandwidth and a corresponding transmitting power of the terahertz transmitting antenna. The terahertz transmitting antenna with the increased transmitting bandwidth and the increased transmitting power can be applied to a small sized terahertz spectral detection device to assist the transmitting source to transmit the signal in the terahertz band. The terahertz transmitting antenna adopting the multi-frequency switching technology can reduce an operation time of a spectral fingerprint recognition algorithm to rapid identify specific target substances.

Dependent claims

A terahertz transmitting antenna, comprising:

a substrate comprising a first surface and a second surface opposite to the first surface;
a microstrip feed line disposed on the first surface;
at least two antenna switches spaced from each other and disposed on the second surface;
at least one conducting plate disposed on the second surface, and one conducting plate is disposed between each two adjacent antenna switches;
an insulating layer covering the at least one conducting plate and the at least two antenna switches, the at least one conducting plate and the at least two antenna switches being disposed between the insulating layer and the substrate;
and
at least two antenna patches spaced from each other and disposed on a surface of the insulating layer away from the substrate;
wherein each antenna switch is opposite to one antenna patch such that a terahertz wave transmitted in the microstrip feed line generates an excitation to the antenna patch through the antenna switch.
