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.
