A dual-polarized, conformal, and lightweight 4×4 L-band antenna array tailored for unmanned aerial vehicle applications is proposed. The array is fabricated using stacked copper-cladded polyimide films and PF-4 foam layers, making it well-suited for weight-constrained airborne platforms. In the flat configuration, the antenna has a bandwidth of 1.17–1.32 GHz, cross-polarization levels better than 24 dB, a gain of approximately 19.9 dBi at 1.25 GHz, and stable radiation patterns across the operating band. RFSoC integration allows real-time phase control of each element, enabling beamforming and directional radiation in both flat and conformal configurations.
