The measured gain at 20 GHz is 35.6 dBi with the aperture efficiency of 54.4% under linear-polarization (LP) excitation, and the gain is 35.4 dBi with the aperture efficiency of 52% under ...

Abstract: In this letter, a wideband high-efficiency circularly polarized transmitarray antenna with linear-to-circular polariza-tion (LP-to-CP) conversion is proposed. The element consists of a ...

Researchers at the John and Marcia Price College of Engineering have now developed such a device: one that can be adjusted on the fly to give light different degrees of circular polarization.

Microwave linear to circular polarisers have received significant historical ... In addition the latter arrangement exhibited dual band functionality; for the same structure and polarization of the ...
