介绍了一种工作在300 GHz的低成本、小型化、高增益的法布里-珀罗腔（FPC）天线。该天线采用激光切割黄铜技术制造。该天线由七个金属层组成：一个接地层，一个集成的阶梯喇叭元件（三层），一个耦合层，一个腔体层，和一个孔径频率选择表面（FSS）层。建议的孔径FSS功能作为一个部分反射表面，有助于定向光束辐射。为了验证，所提出的亚太赫兹（THz）FPC天线原型的开发，制造和测量。所提出的天线在282至304 GHz的带宽为22 GHz的范围内具有低于− 10 dB的测量反射系数。在289 GHz时测得的最大增益为17.7 dBi，从285到310 GHz的增益高于14.4 dBi。测量的辐射方向图显示出高度方向性的方向图，在所有切割平面的整个频带内交叉极化水平低于− 25 dB，这与仿真结果一致。该天线具有结构紧凑、制作成本低、增益高、工作带宽宽等优点。天线的总高度为1.24（设计频率300 GHz），尺寸为2.6 mm × 2.6 mm。所提出的亚太赫兹波导馈电FPC天线适用于6 G无线通信系统。
A low-cost, compact, and high gain Fabry–Perot cavity (FPC) antenna which operates at 300 GHz is presented. The antenna is fabricated using laser-cutting brass technology. The proposed antenna consists of seven metallic layers; a ground layer, an integrated stepped horn element (three-layers), a coupling layer, a cavity layer, and an aperture-frequency selective surface (FSS) layer. The proposed aperture-FSS function acts as a partially reflective surface, contributing to a directive beam radiation. For verification, the proposed sub-terahertz (THz) FPC antenna prototype was developed, fabricated, and measured. The proposed antenna has a measured reflection coefficient below − 10 dB from 282 to 304 GHz with a bandwidth of 22 GHz. The maximum measured gain observed is 17.7 dBi at 289 GHz, and the gain is higher than 14.4 dBi from 285 to 310 GHz. The measured radiation pattern shows a highly directive pattern with a cross-polarization level below − 25 dB over the whole band in all cut planes, which confirms with the simulation results. The proposed antenna has a compact size, low fabrication cost, high gain, and wide operating bandwidth. The total height of the antenna is 1.24 ( at the design frequency, 300 GHz) , with a size of 2.6 mm × 2.6 mm. The proposed sub-THz waveguide-fed FPC antenna is suitable for 6G wireless communication systems.
