## 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

## 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
In this study, a thin resisti¨e sheet is wrapped around a ( ) three-layered skin, fat, muscle elliptical model, and the shielding effect is calculated using the method of moments which applies the equi¨alent resisti¨e approximation.
## Abstract This article presents low‐profile configurations of the Fresnel zone plate antenna at Ka‐band. 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
