A study of the characteristics of a microwave spherical zone plate antenna

Abstract

The possibility of a microwave spherical zone plate antenna has been discussed. A number of formulae describing the characteristics of spherical and plane zone plate antennas are derived. Both the plane and spherical incident wave-fronts are used in the derivation of the formulae. Numerical results comparing the spherical and plane zone plate antennas have been given. It is found that a considerable reduction in the aperture dimension can be achieved by using a spherical zone plate antenna. © 1973 Taylor and Francis Group, LLC.
