Efficient computational design for an antenna with a finite ground plane

Abstract

An efficient method for computational design for an antenna with a finite ground plane was devised. A matrix equation by means of using voltage flows was formulated by using an inverse-matrix/reverse-equation method within the method-of-moment (MoM) framework. Double-layered -zigzag-indexing for discretized induced currents provides a matrix equation incorporating a small work area. The radiation power expressed by voltage flows that appear only in this area is derived. Matrix equation based on voltage flow and radiation power enables practical computational design of an antenna by using a commercial PC with small memory.
