An SDR-Integrated Dual-Band Directional Antenna System for Counter-Drone RF Link Suppression: Design and Open-Field Validation
This paper presents a single-fed dual-band stacked antenna developed for directional counter-drone RF link suppression at the 2.45 GHz and 5.8 GHz ISM bands. The proposed antenna combines a partial ground structure, a metallic reflector, two circular parasitic-resonator layers, and a frequency-selective surface within...
