Multi-functional miniaturized slot antenna system for small satellites

This paper presents the design of a multi-functional miniaturized slot antenna system in S-band for micro/nano-satellites. The antenna system makes use of the spacecraft structure allowing a high integration level within the satellite surface. The same antenna system is able to produce three different operating modes: a) omnidirectional full-coverage, b) one directive beam, and c) four tracking-lobes at a time. The paper focuses on the main aspects of the implemented structure and the obtained results.
