摘要

This research presents a revolutionary dual-band flexible antenna based on an inventive circular–rectangular (CR) array architecture. To achieve dual-band operation without increasing antenna size or structural complexity, the work’s main innovation is the integration of circular and rectangular radiating elements into a single compact array on a flexible polyamide substrate. This procedure is done in conjunction with a strategically engineered defected ground structure (DGS). In contrast to traditional dual-band antennas that depend on intricate feeding networks or multilayer arrangements, the suggested design optimizes the ground plane and modifies the radiating plane geometrically to achieve frequency selectivity. The antenna works well in the 5.83–6.08 GHz (V2X) and 5–5.10 GHz (5G) bands. With peak gains of 3.34 dBii and 3.53 dBii for the 5G and V2X bands, respectively, it attains high radiation efficiencies of 91.75% and 99.22%. The tight match between experimental and simulated data validates the suggested idea. The suggested CR array antenna is a unique and workable option for next-generation flexible and vehicle wireless communication systems because of its steady radiation properties, high efficiency, mechanical flexibility, and structural simplicity.
