Ultrawideband Tapered Slot Antenna With Phase-Correcting Dielectric Lens Loaded
An ultrawideband (UWB) tapered slot antenna with a dielectric lens loaded is proposed. Despite their wide bandwidth and cost-effectiveness, traditional Vivaldi antennas often suffer from a discernible imbalance between gain bandwidth, return loss bandwidth, and high directional pattern bandwidth. In this letter, by analyzing the phase shift properties of substrate materials, an antenna design is proposed without increasing its radiating arm length. Such a design realizes a remarkable UWB impedance bandwidth spanning from 0.6 GHz to 20 GHz. By loading a dielectric lens, a significant gain enhancement of up to 4.7 dB is achieved from 12 GHz to 20 GHz. Such gain enhancements elevate the antenna's performance, making it exceptionally suitable for broadband direction-finding systems, UWB spectrum sensing systems, and other high-gain demand applications.
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.
