A Design of ADS-B Receiver Antenna using Truncated Circular Microstrip Patch in Cubesat Form Factor

Automatic Dependent Surveillance-Broadcast (ADS-B) is an aircraft surveillance technology which is used to monitor the aircraft traffic. To extend the ADS-B monitoring area, an ADS-B receiver can be installed on a low earth orbit (LEO) satellite, e.g. a nanosatellite. An antenna is needed to be installed on the nanosatellite to capture the ADS-B signal from the aircrafts. In this work, an ADS-B receiver antenna is presented. The challenge in this work is to design the ADS-B receiver antenna to be fit into a cubesat platform, a popular nanosatellite form factor. This antenna design follows antenna microstrip configuration. This is non-deployable antenna type which can be used directly after the cubesat released from the launcher. It uses circular patch with a truncated structure to produce circular polarization. This antenna substrate contains two layers of RO3006. This method is used to increase the antenna gain performance. This work result shows that the antenna has successfully satisfied the requirements set on this work.
