  • Abstract
    The spherical annular microstrip antenna is analyzed. The antenna is excited by a coaxial line. The general transmission line model (GTLM) is used to compute the input impedance. The radiating TM12 mode is considered because of its wide band. The effect of the other radiating modes and the nonradiating modes on the TM12 mode is investigated. The effect of different parameters on the input impedance is considered. The radiation patterns are computed using the method of moments
