Influence of surface-wave excitation on efficiency of space-wave launching in microstrip disc antennas
Abstract
The cavity model with magnetic side walls and dyadic Green's functions was used to study microstip 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 with permittivity equal to 2.55 and 9.60. The results are useful for the design of these antennas.
