Deployable Tightly Coupled Dipole Arrays For Small Satellites, Maxence Carvalho
FIU Electronic Theses and Dissertations
This dissertation presents the theory, design, fabrication, and verification of several critical components for a novel class of origami-based and deployable Tightly Coupled Dipole Arrays (TCDAs) suitable for small satellite applications. This work introduces a new approach to enhance the bandwidth of TCDAs by incorporating a semi-resistive Frequency Selective Surface (FSS) network within the substrate. The integration of this FSS network within a dual-polarized TCDA led to an increased impedance bandwidth of 28:1 from 0.20 GHz to 5.6 GHz. Concurrently, losses above 2.5 GHz are reduced to achieve a radiation efficiency of 83% on average. A major component of the …
