Modeling and measurement of metamaterial antenna reception performance based on Software Defined Radio

In this paper, a broad bandwidth, high gain rectangular patch antenna using planar-patterned metamaterial concept and its power reception performance are discussed. Top patch consists of separated micro triangular periodic gaps while the ground plane is etched with crossed strip-line gaps. The patterned metal patch and ground plane form a coupled capacitive-inductive circuit of negative index metamaterial. In addition, experimental and theoretical power reception performance of the metamaterial antenna for different selected intervals are compared by using Software Defined Radio.
