  • Abstract
    The cavity model with magnetic side walls and dyadic Green´s functions was used to study microstrip disc antennas. Curves of efficiency of space-wave launching and directivity as functions of the ratio of the dielectric thickness to the disc radius d/a are shown for two dielectrics: ¿r=2.55 and 9.60. The results are useful for the design of these antennas.
