In this paper, a zeroth-order resonating circular patch antenna with triangular stub is proposed. The proposed antenna has an electrical size of 0.23λ0 × 0.13λ0 × 0.01λ0 with an impedance bandwidth (|S11| < −10 dB) of 21.4% (resonating frequency 2.8 GHz). Circuit values of proposed equivalent circuit have been extracted using advanced design system to plot dispersion diagram which shows zeroth...
In this paper, split ring resonator (SRR) loaded metamaterial (MTM) antenna with CPW and microstrip feed have been proposed. Two antenna structures are presented which have an antenna size of 50 mm × 40 mm × 2.56 mm. The proposed structure with CPW feed shows dual-band behavior with an impedance bandwidth of 9.1% (centered at 1.54 GHz) for first band and 9.8% (centered at 2.86 GHz) for second band...
