Augmented Circular UWB Antenna for Dual-Band WLAN and C-Band Communication in Military Mini-Drones

Abstract

This paper presents a novel UWB circular microstrip antenna (UWB-CMSA) designed for handheld devices with a partial ground plane, achieving resonance from 1.5 GHz to 11.2 GHz.  The antenna effectively covers various bands including GPS (1.575 GHz), DCS (1.71–1.88 GHz), PCS (1.85–1.99 GHz), UMTS (1.925–2.175 GHz), Bluetooth (2.4 GHz), LTE (2.5/2.69 GHz), WLAN (2.4/3.5/5 GHz), WiMAX (2.5/3.5/5.5 GHz), and X-band applications (8-12 GHz) encompassing satellite communication and military radar. The antenna exhibits good gain values (ranging from 2.45 dB to 5.5 dB) across these desired frequency bands and maintains high efficiency. The design was validated through fabrication and Vector Network Analyzer (VNA) measurements, demonstrating excellent agreement with simulated results. Uniquely, the antenna is shaped like the emblem of the Algerian Civil Protection Agency, allowing for seamless integration into their equipment (drones, communication devices, fire trucks, etc.). This integration enables diverse applications in the 1.5 – 11.2 GHz range, including identification, localization, and environmental monitoring in critical situations. Furthermore, the proposed design incorporates the Civil Protection emblem for potential performance enhancement when mounted on mini-drones. CST software was employed for design and simulation purposes.
