Design and Characterization of a Multi-Channel ADS-B Antenna for Small Satellites

This paper presents the design of a multi-channel ADS-B antenna made to receive aircraft localization and identification signals - Automatic Dependent Surveillance-Broadcast (ADS-B) - at different angles of arrival on a satellite. The single patch antenna design and material selected is suitable for the harsh environment in space. The paper presents measurement results that have been obtained at a compact test range.
