The Influence of Conducting Bodies of Revolutions on the Radiation Characteristics of Circular Loop Antennas

Samier M. Ali Hamed, Mohammed A. H. Abbas

Abstract


The effect of a conducting body of revolution placed coaxially relative to circular loop antenna,
on the radiation characteristics of the loop antenna is studied using the well-known theory for
the circular loop antenna with numerical Green’s functions for bodies of revolution. The
structures composed of loop/sphere; loop/cone-sphere, loop/open cylinder, loop/disk, and
loop/toroid are considered in the study. An alternative technique is provided to study the
interesting problems of the loop antenna over finite ground plane and the array of two loops.
The results of this study are in good agreement with published result for cases of the loop over
the finite ground plane and the array of two loops.

Keywords


bodies of revolution; circular loop antennas; green function; conducting bodies.
