Abstract

This letter introduces a novel high-gain, high-order-mode-based pattern-reconfigurable antenna designed for intelligent wireless applications. To achieve a higher gain, a high-order-mode slot radiator is employed. Then, by manipulating the field distributions of the long slot, different excitation modes are activated, leading to the development of a novel high-order-mode control concept. The long slot can switch between broadside and dual-beam patterns by exciting different slot modes (full-wavelength slot or second-order slot mode). To validate the high-order-mode control concept, a pattern-reconfigurable slot antenna is designed, fabricated, and measured. By switching different feeding paths, the reconfigurable antenna can obtain a pair of complementary beams. Besides, the measured peak gains for these two modes are 11.1 dBi and 7.0 dBi, respectively. The proposed reconfigurable antenna boasts a simple yet ingenious structure (low cost), high gain, broadband capabilities, and excellent pattern diversity. It is an ideal candidate for intelligent wireless applications, including Internet of Things (IoT), WiFi, Fiber-to-the-Room (FTTR), and microcells.

智能物联网应用中具有模式可重构性的高阶模天线

这封信介绍了一种新型的高增益，基于高阶模式的模式可重构天线，设计用于智能无线应用。为了获得更高的增益，采用了高阶模槽辐射器。然后，通过控制长槽的场分布，激活不同的激励模式，从而发展了一种新的高阶模态控制概念。通过激发不同的槽模式（全波长槽或二阶槽模式），长槽可以在宽频和双波束模式之间切换。为了验证高阶模控制概念，设计、制作并测量了一种模式可重构的缝隙天线。通过切换不同的馈电路径，可重构天线可以获得一对互补波束。此外，这两种模式的测量峰值增益分别为11.1 dBi和7.0 dBi。所提出的可重构天线具有结构简单而巧妙（低成本）、高增益、宽带性能和出色的方向图分集等优点。它是智能无线应用的理想候选者，包括物联网（IoT）、WiFi、光纤到房间（FTTR）和微蜂窝。

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.
