摘要

In this Letter, a high-gain sub-terahertz lens horn antenna with a metal guide is proposed. In this antenna, high gain is achieved by using a metal guide and dielectric lens. The experimental results show that the impedance bandwidth of the proposed antenna is above 200 GHz, and the measured peak gain of the antenna is 39 dBi at 240 GHz.
