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.

This paper presents an ultra-wideband tapered slot patch antenna with bi-directional radiation, reconfigurable for dual band-notched capability and fed by coplanar waveguide. The proposed antenna showed excellent ultra-wideband characteristics with bandwidth of (1.9–12 GHz). In order to reduce the interference of the narrow band communications represented by Worldwide Interoperability for Microwave Access radiation in the range (3.4–3.9) GHz and standard IEEE 802.11a. application (from 5.1 GHz to 6.1 GHz), the antenna was accompanied with adjustable dual-stop band capability in these bands. The dual-band notches are achieved with aid of inserting a parasitic single split ring resonator and etching a single circular complementary circle split ring resonator. The proposed antenna used epoxy (FR4) substrate material with ????r= 4.4 and dimensions of .
