Analysis of finite Phased Arrays on Shaped Ground Planes.

Abstract

The objective of this thesis is to evaluate the performance of an array antenna when it is installed on an complex structure, such as those that have unusual edge contours, curved surfaces, and mixed material composition. A dipole is used as the basic array element to study the effect of various changes in the array design parameters on the gain and sidelobe level. Data is generated using a computational electromagnetics code based on the method of moments. Among the issues addressed are the curvature of the array ground plane and shaping the ground plane edges to reduce wide angle sidelobes.
