Design of Metamaterial Agile Radiation Pattern Microstrip Antenna

Abstract

in this thesis We are interested with the antenna agility,The agility is Introduced by using agile metamaterials ,Agile metamaterials allow one to adjust the electromagnetic Response in real time. This tuning ability helps make metamaterial Devices more versatile, adapting to shifting input or changing target Parameters. However, those methods for enabling frequency-agile Metamaterials require continuous application of an external stimulus To maintain altered metamaterial properties. The aim of introducing agility is to control the antenna characteristics Such as directivity, gain, radiation diagram and operating frequency.
