Linear-to-Circular Polarization Conversion from Impedance Loading of Single-Port Patch Antennas
Résumé
Electromagnetic theory of antenna scattering has been previously applied to the minimization/maximization of radar signatures, and has been eventually used for designing antenna sensors for passive wireless sensing systems, in which the antenna backscattering mode is controlled by loading impedances. To mitigate the clutter and reduce polarization mismatch in such wireless systems, this paper investigates the linear-to-circular conversion of electric field from loading single-port patch antennas by passive impedance.
