TERAHERTZ TRANSMITTING ANTENNA AND TERAHERTZ SPECTRUM DETECTING DEVICE

WIPO Patent Application WO/2019/174148

A1

The present application relates to a terahertz transmitting antenna, comprising a microstrip feeder line, a substrate, at least two antenna switches, at least one conductive plate, an insulating layer, and at least two antenna patches. The terahertz transmitting antenna is provided with the at least two antenna switches and the at least two corresponding antenna patches, which sufficiently increases the transmission bandwidth and the corresponding transmitting power of the terahertz transmitting antenna. The terahertz transmitting antenna with a wide transmitting frequency band and high transmitting power can be applied to a small terahertz spectrum detecting device to assist a transmitting source in transmitting signals in the terahertz band. The terahertz transmitting antenna splices a plurality of terahertz sources having different transmitting frequency bands by means of a multi-frequency transmitting antenna array so as to realize spectral detection of a wide frequency band. The terahertz transmitting antenna uses a multi-frequency transmission switching technology, which can reduce the operation time of a fingerprint spectrum recognition algorithm so as to realize rapid identification of a specific target substance.
