Abstract

Transparent metasurface-loaded flexible antenna for the X band. The dumbbell-shaped metasurface is a type of polarization conversion unit arranged in a checkerboard pattern. This structure achieves 10 dB linear polarization radar cross-section (RCS) reduction under vertical incidence within the 9.2 GHz to 21.2 GHz range. Attach it to a slotted antenna array powered by a 1-to-4 Wilkinson power divider. The antenna has good radiation characteristics within the bandwidth of the X band. This antenna design boasts a low profile (0.14

${{\lambda }_0}$

), flexibility, and interference resistance. In the 0°–90° central angle bending scenario, the structure maintains good RCS reduction and antenna radiation properties, while also effectively reducing electromagnetic waves at 0°–45° angle, making it highly suitable for wider applications such as detection radar, satellite communications, and medical equipment.

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.
