A miniaturized dual-band CPW-fed metamaterial antenna is presented and developed in this paper. Zeroth-order mode is originated by realizing open-ended composite right/left-handed transmission line. A dual split ring resonator is introduced to obtain another mode. The antenna is operated in the frequency region 1.60–1.64 and 2.76–2.79 GHz. Shunt inductance is offered by means of thin stripline connecting ground planes. It is demonstrated that by applying metamaterial loading (thin stripline) proposed antenna is capable to achieve 51.9% miniaturization with respect to the antenna without metamaterial loading. The presented antenna has an electrical size of 0.162 λ0 × 0.108 λ0 × 0.008 λ0 at f0 = 1.62 GHz. The antenna exhibits simulated gain of 1.05 and 2.59 dB in the broadside directions at 1.62 and 2.78 GHz, respectively. Beside that this antenna offers dipolar-type pattern and omnidirectional pattern in the xz-and yz-planes respectively at both bands, which is beneficial to be used in modern wireless applications. The design methodology of the proposed antenna is described with the help of current distributions and parametric analysis.

Parasitic Patch

The paper presents a novel dual-band patch working at GSM band and S-band. The patch encompasses a rectangular radiator coupled with a parasitic patch in the coplanar region and a split ring resonator in the ground region. The patch is analyzed numerically and is synthesized using the HFSS simulator. Finally, the performance characteristics of the model are measured and are compared with numerical and simulated results. The patch gives two different bands at 950MHz and 2.3GHz and gives -10dB impedance bandwidth in the lower band from 950MHz -1GHz and higher band from 2.275GHz – 2.325GHz. The patch also accomplishes a gain of 4.74dBi in the effective band 1 and 4.02 dBi in the operating band 2.
