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.
