Silicon Carbide Antenna for Polarization Agility in Constrained Environments
Résumé
This paper highlights the advantages of designing a reconfigurable antenna on silicon carbide (SiC) substrate. The semiconductor properties of the SiC allows co-design of the antenna and the active elements. Co-design meets the objectives of stability at high temperatures, high-power management, high-performance, a high level of integration and cost-effectiveness. The proposed patch antenna works at 12.1 GHz switching from a linear polarization to a circular one. Reconfigurability is achieved using a distributed doped area, forming a serial integrated junction in the substrate.
