| contents | <p>This paper presents the design and analysis of an L-band antenna for Automatic Dependent Surveillance–Broadcast (ADS-B) signal reception from Low Earth Orbit (LEO) satellites at 1090 MHz. The proposed antenna is based on a six-faced prismatic array configuration that achieves omnidirectional coverage in the azimuth plane. Each face integrates a compact 4×2 subarray built from a miniaturized circular microstrip patch element with T-shaped extensions and dualport excitation for circular polarization. The unit cell exhibits a reflection coefficient better than −10 dB and an axial ratio suitable for mitigating ionospheric rotation effects. Experimental validation of a 2×2 prototype confirms the simulated results, with a measured gain of 11.27 dB and a −3 dB beamwidth of 46.3◦. This preliminary design demonstrates the feasibility of<br>integrating compact, high-performance antennas for spaceborne ADS-B reception systems, supporting global air traffic surveillance in remote and oceanic regions.</p> |
