UHF and S-band Antenna Arrays for Nano-Satellite-Based Data-Relay

In this work, two antenna arrays to receive and retransmit environmental data over a nano-satellite are presented. The main challenge was to integrate an unidirectional antenna operating in UHF onto the nano-sat. The comparison between computational and measured results are presented and discussed, whereby good performance in terms of radiation properties has been obtained for both UHF and S-band arrays.
