The truncated dielectric-coated conducting sphere-radiation and gain characteristics

Abstract

An exhaustive study of the radiation and gain characteristics of a truncated dielectric-coated conducting spherical antenna excited in the symmetric TM mode has been reported. The effect of the various structure parameters on the radiation and the gain characteristics for a few even and odd order TM  modes for different structures is shown. The theoretical radiation patterns and gain have been compared with experiment. It is found that there is good agreement between theory and experiment in the case of TMoli and TMo6 modes. A theoretical and experimental study of the radiation and gain characteristics in the frequency range s-o to 12·0 GHz has been reported.
