抄録: An oblate spheroidal antenna (OSA) has been proposed to widen the beamwidth of microstrip antennas (MSA). OSA consists of a linearly polarized circular patch MSA inserted between oblate spheroidal conductors. The electromagnetic fields within the MSA are expressed as the summation of modal functions in the cylindrical coordinate system. Their unknown coefficients and the equivalent electric and magnetic currents on antenna surface are determined by the magnetic field integral equation on the aperture of the substrate and the electric field integral equation on the conductor surface. The antenna beamwidth becomes wider and the resonant frequency decreases as the conductor height increases.
