Abstract

The coupling between multiple cavity-backed slot antennas placed arbitrarily with respect to each other on a flat conducting surface is calculated using an iterative finite element-boundary integral (FE-BI) method in conjunction with domain decomposition. Each cavity is independently analyzed using the hybrid FE-BI approach, whereas the field interaction between the slots is taken into account through an iteration algorithm. The approach provides substantial computational savings both in terms of memory storage and CPU time. The algorithm converges within only a few iterations and the results compare favorably with the hybrid Fe-Bi direct approach..
