Dimensional parametric study of the spiral resonator as a metamaterial planar-antenna

In this paper, the square spiral resonator (SR) as a metamaterial planar-antenna with electromagnetically coupled (EMC) feed is proposed. The proposed antenna will be operated at the frequency range of 2.4-2.5 GHz. To define the dimensional parametrics of the proposed antenna such as the spiral turn number (N), strip width (w), and gap width (s), it is simulated. The highest gain obtained is -0.5 dB at the frequency of 2.43 GHz by using dimensional parametrics of N=3; w=3.1mm; and s=0.5mm.
