摘要

本文提出了一种基于复合左/右超材料的广角扫描漏波天线。所提出的LWA集成了带有辐射槽的单元格，该辐射槽由带阶梯指的数字间电容形成，通过微带延迟线相互连接。创新的散热器设计实现了4 GHz至6.7 GHz的宽阻抗带宽，并允许波束在- 62°至30°的范围内转向。该天线的峰值增益为10.5 dBi，辐射效率一直很高，在工作范围内平均为72%。这款高性能的LWA结合了简单的设计和紧凑的外形因素，提供了一种经济高效且易于制造的解决方案。它专门针对c频段进行了优化，非常适合5G和6G应用。

A Frequency-Agile and Wide-Scanning CRLH Leaky-Wave Antenna for Advanced Wireless Systems

This letter presents a wide-angle scanning leaky-wave antenna (LWA) based on composite right-/left-handed metamaterials. The proposed LWA incorporates unit cells with a radiating slot formed by an interdigital capacitor with stepped fingers, interconnected through microstrip delay lines. The innovative radiator design achieves a wide impedance bandwidth of 4 GHz to 6.7 GHz and allows beam steering across a range of −62° to 30°. The antenna demonstrates a peak gain of 10.5 dBi and consistently high radiation efficiency, averaging 72% over the operating range. This high-performance LWA combines a simple design with a compact form factor, offering a cost-effective and easily manufacturable solution. It is specifically optimized for the C-band spectrum and is well-suited for 5G and 6G 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.
