High-Order-Mode Antenna With Pattern Reconfigurability for Intelligent IoT Applications
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.
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.
