## Abstract A novel reflectorโbacked 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 hexagonalโcut zones is presented. This new structure was simulated at 30 GHz using a finiteโdifference timeโdomain software to study its gain and sidelobe levels in relation to the standard circular FZPA and the hexagonal FZPA. Several prot
## Abstract This article presents lowโprofile configurations of the Fresnel zone plate antenna at Kaโband. The investigation involved progressively reducing the focal distance of the antenna through simulations and observing the effect on the directivity, radiation patterns, and aperture efficiency
## Abstract An improved zoning rule is presented for designing a square Fresnel zone plate lens (FZPL). This new rule results in a higher gain when the FZPL is used as an antenna element or can enhance the focusing properties of the square FZPL when used to collimate an incident plane wave. The der
