Polarization Reconfigurable Patch Antenna Using ScDDAs
Résumé
This paper deals with a patch antenna presenting a reconfigurable polarization using semiconductor distributed doped areas (ScDDAs). This on-chip antenna offers a switch able polarization between two linear ones. The monolithic integration of the ScDDAs as active elements directly in the substrate avoids additional components and gives design flexibility. The antenna and the ScDDAs are co-designed and manufactured in a same process flow. The commutation is achieved with a DC bias of − 2.2 V. The measured results fit well with the simulated ones.
