Design And Characterization Of Rectangular Array Microstrip Antenna For Cubesat S-Band Transmitter

Automatic Dependent Surveillance-Broadcast (ADS-B) is an air traffic surveillance technology that automatically and periodically broadcasts onboard aircraft flight information such as identity numbers, positions, speeds, and destinations during all phases of flight to avoid collisions. In the future, the radar system will be equipped or even replaced by the ADS-B ground station. Therefore, the Nano-Satellite Laboratory of Telkom University is developing a satellite technology called Tel-USat which the ADS-B receiver is one of the missions. This work focuses on the design and characterization of the antenna to send all the collected ADS-B data to the ground. This antenna is designed by using an FR-4 substrate material with two rectangular patches, linear array, T-junction power divider, and proximity coupled rationing. The results obtained during the measurement are return loss values at 2.4 GHz frequency of -18.5 dB, VSWR of 1.2, antenna bandwidth of 163 MHz, and the gain of 6.08 dB.
