Abstract

Abstract:
A rectangular planar array antenna design using thinning technique and Genetic
Algorithm (GA) optimization technique are used to minimize the gain variation for Low
Earth Orbit (LEO) satellites antenna. This design controls the feeding amplitude through
thinning without requirements to control the phases which yields to simplify the feeding
network.
Two antenna elements are proposed, cos1.5 􀈙 radiation pattern element and the
rectangular patch element.
A simple genetic algorithm optimizer is used to get the optimum excited elements on
the array.
