Abstract

A wideband, high-gain millimeter-wave (mmW) endfire Fabry–Pérot Cavity (EF-FPC) antenna with high efficiency has been proposed in this letter. The proposed antenna with a simple structure consists of two metallic slabs and a single-layer printed circuit board substrate. By utilizing the self-mismatch scheme of the interface between substrate and air, intrinsic partial reflection can be achieved without the need for an independent partially reflective surface. Combined with a via-based shaped ground within the single-layered substrate, multiple resonant modes can be excited, contributing to bandwidth and gain enhancement. After measurement, the overlap bandwidth of the antenna is 11.45%, and it has a peak gain of 15.64 dBi. The proposed antenna yields a radiation efficiency of 95% and a maximum aperture efficiency of 92%, respectively. Notably, this is the first time that an EF-FPC antenna with a simple structure is realized. With the characteristics of wideband, high-gain, high-efficiency, low-profile, and low-complexity, the proposed antenna has enormous potential for application in next-generation communication systems.

无独立部分反射面的宽带、高增益、高效率毫米波端射法布里-波腔天线

本文提出了一种宽带、高增益、高效率的毫米波末端法布里-帕姆罗特腔（eff - fpc）天线。该天线结构简单，由两个金属板和一个单层印刷电路板基板组成。利用基板与空气界面的自失配方案，无需独立的部分反射表面即可实现本征部分反射。结合在单层衬底内的基于过孔的形地，可以激发多个谐振模式，有助于带宽和增益增强。经测量，该天线的重叠带宽为11.45%，峰值增益为15.64 dBi。该天线的辐射效率为95%，最大孔径效率为92%。值得注意的是，这是首次实现结构简单的EF-FPC天线。该天线具有宽带、高增益、高效率、低轮廓、低复杂度等特点，在下一代通信系统中具有巨大的应用潜力。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
