  • Abstract
    A more rigorous model of the probe-fed hemispherical antenna than that of K. W. Leung et al. (1991) is considered. This model accounts for all possible azimuthal modes that can be excited by this structure. The input impedance is computed for a dielectric sphere antenna of radius a=2.54cm, /spl epsi//sub r1/=8.9, and loss tangent 0.0038.<>
