## Abstract A novel Fresnel zone plate antenna (FZPA) with hexagonal‐cut zones is presented. This new structure was simulated at 30 GHz using a finite‐difference time‐domain software to study its gain and sidelobe levels in relation to the standard circular FZPA and the hexagonal FZPA.

## Abstract The performance of Fresnel zone plates having polygonal boundaries between zones has been studied for polygons with a low number of sides. An optimized polygonal shape has been analytically defined by minimizing the mismatched area between the circular and the polygonal pseudo‐Fresnel z
