Abstract

This paper introduces a new low cost, robust miniaturized microstrip antenna inspired with metamaterial split ring resonator structure (SRR). Because of metamaterials property there has been considerable reduction in size. The overall antenna structure is phi shaped which is equivalent to two SRRs placed back to back. This phi shaped antenna (PSA) thus obtained has been simulated on EM solver Ansoft HFSS and scattering matrix parameters are analysed. Excellent performance in terms of size and radiation pattern is achieved. These types of antennas are very useful for applications where space of equipment is a constraint.

Key words: Metamaterial, split ring resonator, microwave, microstrip structures, miniaturized antennas.
