摘要
A terahertz (THz) low-profile corrugated horn antenna is proposed. This antenna consists of WR2.2 feeding waveguide, pyramidal horn, and four V-grooves, integrated fabricated by silicon micromachining. The grooves significantly enhance the gain and maintain the low profile of original horn antenna. The measured results from 480 to 500 GHz show the gain above 15.6 dB and the narrow beamwidths without sidelobe, agreeing well with simulated results and indicating the potential to be applied in compact array of THz imaging and detection systems.
