Circuit Modeling Of Planar Meshes With Discrete Loads

A technique for calculating the equivalent mesh impedances for a doubly periodic mesh which may contain small discrete loads is demonstrated. The mesh is modeled by a two port network. One port is shunted across a transmission line that carries the incoming and outgoing waves. The discrete load is placed across the second port. The equivalent port impedances are calculated without approximation using the method of moments. This technique allows predictions to be made of the performance of a mesh with arbitrary load since the port impedances are load independent. It also allows the design of variable meshes in which the lumped load is adjusted externally.
