ADS-B Microstrip Antenna Receiver Design for Cubesat with Slot

Nanosatellite is one of several satellite classes that have a size that generally refers to the standardization of cubesat which is 10×10×10 cm

. Nowadays nanosatellite is widely developed for various purposes such as air traffic monitoring using Automatic Dependent Surveillance- Broadcast (ADS-B) receiver as the mission. Telkom University and the nanosatellite Laboratory are researching ADSB on nanosatellite. The nanosatellite uses a frequency of 1090 MHz which functions as ADS-B receiver, and air traffic control as the primary mission. This paper presents a microstrip antenna design for nanosatellite with the mission as ADS-B signals receiver. the antenna has voltage standing wave ratio (VSWR) = 1,9 in the frequency of 1090 MHz. Then have unidirectional as the radiation pattern and right hand circular polarization (RHCP) as the polarization, gain 1,02 dB, 52 MHz bandwidth and range is 189 km.
