Abstract

The application of an integral-equation moment method to the analysis of microstrip wire-grid antennas is discussed. The formulation has been implemented in computer code, which can be used to perform numerical experimentation. A coaxial-fed five-element etched linear array on a dielectric substrate is considered as an example. Such an analysis makes it possible to carefully design for some desired aperture distribution. Computed patterns are shown to compare favorably with measured results.<>
