Abstract

Factors that affect the efficiency of a phase-correcting Fresnel zone plate (FZP) lens antenna are analyzed. These include attenuation, diffraction, and reflection losses. The FZP efficiency is compared to that for a standard lens, and the FZP is shown to be better at millimeter wavelengths, where attenuation is an important factor.
