摘要

对紧凑型天线的追求在历史上牺牲了指向性。传统上，解决方案包括增加散热器、复杂透镜或扩大天线，这通常会引入假瓣或增加系统高度。本研究研究了一种数字扼流圈和沟槽孔径技术，采用凹槽和突出扼流圈来优化超短角的指向性和形状。通过分析和实验，我们评估了天线的增益、体积效率、带宽和瓣抑制。我们的研究结果为应用提供了见解，并为超短角的超低轮廓数字孔径拓扑的进一步发展奠定了基础。

Ultra-Short Horn Antennas via Digital Choke and Groove Aperture Topologies

The pursuit of compact antennas has historically sacrificed directivity. Traditionally, solutions involve adding radiators, complex lenses or enlarging the antenna, which often introduces spurious lobes or increases system height. This study investigates a digital choke and groove aperture technology, employing recessed slots and protruded chokes, to optimize directivity and shape lobes in ultra-short horns. Through analysis and experiments, we assess the antenna's gain, volume efficiency, bandwidth, and lobe suppression. Our findings offer insights into applications and lay the groundwork for further advancements in ultra-low-profile digital aperture topologies for ultra-short horns.

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.
