“…The sensitivity analysis procedure for antenna arrays is similar to the sensitivity analysis for isolated patches [4]. For example, let us consider how can the sensitivity analysis be used to study the effects of changes in one of the patch dimensions on the Z-matrix of the array.…”

“…The modeling of the edge conductance network used earlier [4], is based on the evaluation of the power radiated by a particular edge of the patch. From the power radiated, we obtain an equivalent conductance which is distributed uniformly over sections of the edge.…”

“…The presence of a dielectric layer over the patch is accounted for in the modeling of edge fields. Dielectric and conductor losses are included by defining an effective loss tangent for the dielectric filling the cavity [4]. For microstrip patch elements of regular shapes [5] (rectangles, circles, rings, sectors of circles and rings and three types of triangles), the Z-matrix characterizing the multiport planar component PATCH can he obtained from Green's functions available for these shapes [5].…”

The multiport network modeling (MNM) approach provides a detailed equivalent network representation of microstrip patches and has been used successfully for C.4D of various microstrip patch configurations. Combined with the network modeling of the mutual coupling among patches and network models for feed lines in the array, the MNM approach provides a convenient frame work for CAD of microstrip arrays. This paper is a review of the state-of-the-art in the use of MNM models in CAD of microstrip arrays.The MKM approach for modeling microstrip patches and the mutual coupling among patches is reviewed briefly. Application of the MNM approach to the CAD of linear series-fed arrays with a cover layer is discussed. The CAD algorithms are described and key advantages of the MNM approach leading to sensitivity. analysis and optimization are highlighted. Extension of the approach to more general two-dimensional planar arrays is outlined.
