Аннотация

In this paper, the design of a patch antenna with a metamaterial composed of circular SRR is proposed. The proposed antenna design is fabricated on FR4 substrate and the experimental results obtained are in good agreement with the simulated results. By using the circular SRR structure the return loss of the conventional patch antenna has been improved from   -11.5dB to -18.5dB. influence of metamaterial designed on another layer characteristics of the conventional patch antenna along with a comparison of characteristics of the conventional patch antenna and the patch antenna with metamaterial is shown. By using the metamaterial the return loss of conventional patch antenna is increased from –11.5dB to –19dB. The antenna is simulated by using MOM based IE3D software. The simulated and experimental results are in good agreement. Keywords: Left Handed Metamaterial (LHMTM), Array of ‘SRR’, Negative permittivity, Negative permeability
