A method-of-moments analysis shows that a practical, nonair dielectric may be used to reduce the separation and physical sue required for optimal performance of a spiral antenna, backed by a ground plane. Microstrip transmission-line impedance equations are shown to be applicable in estimating the e
## 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
