摘要

提出了一种贴片馈电宽带双极化太赫兹喇叭天线。通过堆叠蚀刻石英衬底形成阶梯腔，实现了充气喇叭。采用带h型槽的双极化宽带贴片馈电来激励喇叭。仿真结果表明，该天线在- 10db级的分数阻抗带宽约为19.5%，在182 ~ 222 GHz范围内的峰值增益为13.2 dBi。该天线实现了25dB以上的端口隔离和23dB以上的宽带极化隔离。

A Patch-fed Wideband Dual-polarized Terahertz Horn Antenna Based on Quartz Process

A patch-fed wideband dual-polarized Terahertz (THz) horn antenna is presented in this paper. By stacking etched quartz substrates to form a stepped cavity, an air-filled horn is realized. A dual-polarized broadband patch feed coupled with H-shaped slots is used to excite the horn. According to our simulation results, the proposed antenna could achieve −10dB-level fractional impedance bandwidth of around 19.5% and reach a peak gain of 13.2 dBi from 182 to 222 GHz. The antenna realizes a port isolation more than 25dB as well as broadband polarization isolation of more than 23dB.
