Design and Prototyping of a Low-Cost Parasitic Element Antenna for a Telemetry-Telecommand Link on Ariane 6 Space Launcher

This work presents a first prototype of a TMTC (telemetry-telecommand) S-band reconfigurable antenna, validating the architecture of ESPAR (Electronically steerable parasitic array radiator) in terms of performances, integration and power handling for use on space launcher environment. The originality of this work is based on the design of high efficiency-high power handling reflective phase shifters with reduced size and their association with a large radiating surface.
