Short Papers Detailed Analysis of A Canonical Structure in Electromagnetic Radiation Problems

A canonical structure, devised by an earlier investigator to simplify the computation of radiation from small table-top products and their peripherals, is revisited. Though this structure contains only salient features of actual products, it has previously defied accurate analysis by available tools. In this short paper, the authors calculate the current distribution on the structure using a powerful analysis code they developed, and compare their results against previously measured data. The authors then include a finite-sized dielectric to serve as the substrate for the microstrip transmission line contained in the structure and repeat the analysis. For both structures, the nature of the observed resonances in the current is discussed, and insight into the radiation process is gained. © 1993 IEEE
