Abstract
In this paper, a compact and original feeding circuit architecture is proposed to synthesis the circular polarization of a triband antenna. A diplexer is used in this circuit in order to achieve circular polarization diversity, that is, right-hand circular polarization (RH-CP) for two radio-navigation bands (GPS/Galileo) and left-hand circular polarization (LH-CP) for a telemetry band (MicroSat TM). Simulation and measurement results are presented and validate the proposed feeding circuit concept.
