Abstract

This paper introduces a new low cost, robust miniaturized micro strip high gain 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 equivalently two SRRs placed back to back. This miniaturized phi shaped antenna (MPSA) thus obtained, has been simulated on EM solver Ansoft HFSS and scattering matrix parameters are analyzed. Excellent performance in terms size, gain and radiation pattern is achieved. These types of antennas are very useful for applications where space of equipment is a constraint like microwave detection of skin cancer.

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