Abstract
A full-wave analysis of radiation effects from microstrip discontinuities is presented. Beginning with the dyadic Green's function for a dielectric slab, an integral equation is formulated, which is then solved by the method of moments in obtaining the current distributions along the transmission line, in particular, near the discontinuities. Employing these results, the near and far-zone fields, as well as radiation patterns are computed. It was found that under resonance conditions of 8 GHz the radiation power of a 28.1 mm floating line can exceed 41% of the feeding power, which may cause a potential problem in electromagnetic compatibility. >
