摘要：
In this letter, a terahertz (THz) antenna using metallic lens is proposed and investigated. The metallic lens structure usingmetallic waveguide delay lines has been adopted for the phase compensation and is used to feed a flare structure for enhancing the radiation gain. A prototype with a center working frequency of 412.5 GHz is designed and fabricated by using the low-cost commercial metal milling technology. Experiments show that the fabricated prototype has a return loss larger than 15 dB within the frequency bands of 370-460 GHz. The maximum measured gain is 27.6 dBi at 412.5 GHz. Good agreement between simulated and measured results is obtained. This letter demonstrates that the compact high-gain THz antenna can be realized by using the metallic lens structure with the low-cost commercial milling process.
