Circular to Linear Reconfigurable Polarization Antenna Using Semi-conductor Distributed Doped Areas

This paper presents a novel reconfigurable polarization patch antenna designed on a silicon substrate and using integrated semiconductor distributed doped areas (ScDDAs) as active elements. The antenna is able to commute from a circular to a linear polarization. The co-design between the antenna and the ScDDAs results in a monolithic integration of the active elements in the substrate. This method allows to optimize the global performances in the circular and linear polarizations thanks to the flexibility of the doped area shape and position. A demonstrator is proposed from the simulations to the measurements and validates the proof of concept.
