An improved zoning rule of the Fresnel zone plate

Microwave and Optical Technology Letters, 1999
In the traditional zoning rule of the Fresnel zone plate (FZP), the distance from two edges of each zone to a common focus is progressively increased with a half-wavelength step. In this paper, a more reasonable zoning rule is proposed to further increase the antenna gain by about 1 dB. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 23: 69–73,
