Formulation and Synthesis of Hexagonal Prism Array Using Nature Inspired Algorithm

Abstract

In this dissertation a new architecture of antenna array is proposed in which antenna elements are placed on a Hexagonal Prism in order to obtain split beam radiation pattern.The Hexagonal Prism Array(HPA) is synthesized for amplitude excitation ,complex excitation and relative distance using a novel optimisation technique.As a performance criteria the split beam radiation pattern is evaluated for side lobe level(SLL) and half power beam width(HPBW).The optimisation technique is experimented on conventional arrays like Linear and Planar and a comparative study with the published literature is also performed.An attempt to model the HPA on a commercial software in which radiator is a patch elements.
