Different attachment modes for use within the spectral-domain moment-method analysis of probe-fed microstrip patch antennas are investigated. These modes are used for the accurate analysis of probe-to-patch junctions and, in this paper, two of the most widely used approaches are compared in terms of their ability to model patches of various sizes on substrate materials ranging from quite thin to relatively thick. It finally turns out that the subdomain approach is somewhat more versatile than the entire-domain approach.
