    Abstract

    A rectangular dielectric-resonator antenna, fed by a microstripline through an aperture, is analysed using the finite-difference time-domain method. The antenna operates in the TE1δ1 mode and radiates like a magnetic dipole. The electric and magnetic fields in and around the antenna are presented for various time steps. The radiated far-field waveforms are calculated in several directions, by applying the field equivalence principle directly in the time-domain. The frequency-domain far-field patterns are presented at the resonant frequency. They are similar to the far-field patterns of an elemental magnetic dipole, and compare well with previously measured far-field patterns of a rectangular dielectric-resonator antenna.
