## Abstract A novel reflectorβbacked Fresnel zone plate antenna (FZPA) is presented. The reflector is positioned at the aperture of the feed antenna such that the radiation that was reflected back off the metal zones of the FZPA gets reradiated instead of being lost. This structure enhances the dir
## Abstract A novel Fresnel zone plate antenna (FZPA) with hexagonalβcut zones is presented. This new structure was simulated at 30 GHz using a finiteβdifference timeβdomain software to study its gain and sidelobe levels in relation to the standard circular FZPA and the hexagonal FZPA. Several prot
The application of Fresnel lenses is often made to the receiving antennas for television and radio by way of the satellite communication, for the astronomical observation and so on. Their advantage lies in structural simplicity and low cost. A typical Fresnel zone plate lens (FZPL) consists of coaxi
