Abstract:

The problem of electromagnetic radiation from a circular loop antenna of radius a, carrying a current I is considered. The loop may be radiating in the presence of one or more of the following objects: a centrally located dielectric or perfectly conducting sphere of radius ba and outer radius d, a perfectly conducting spherically symmetric cap at radius b, and another such cap at radius d. Typical geometric structures considered are shown in Fig. 1 . It is demonstrated how the presence of the sphere, shell, and caps can change and direct the radiation pattern of the loop.
