In this paper, a compact zeroth-order resonating (ZOR) metamaterial antenna with coplanar waveguide (CPW) feed is presented. The proposed antenna has an impedance bandwidth of 19.82% centered at 3.33 GHz. The proposed structure having smaller electrical size 0.288 λ0 × 0.186 λ0 × 0.018 λ0, where λ0 is the free space wavelength at ZOR mode (at f0 = 3.33 GHz). In addition, antenna offers peak gain of...
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...
A compact CPW-fed metamaterial (MTM)-inspired zeroth-order resonating (ZOR) antenna is presented with backed ground plane. Such MTM antenna consists of thin conducting line and a bow-tie shaped patch connected to CPW feed. The proposed structure shows compact size with radiating element dimensions of $0.095{{\lambda }_{\text{o}}} \times 0.042{{\lambda }_{\text{o}}} \times 0.013{{\lambda }_{o}}$ by...
In this paper, an ultra-wideband ring-shaped metamaterial antenna with modified phi-shaped split ring resonator has been proposed. The proposed antenna has a size of 35 mm × 37 mm × 1.6 mm and shows dual-band characteristics. The proposed metamaterial antenna has an impedance bandwidth of 14% (centered at 2.65 GHz) and 114.5% (centered at 7.25 GHz) for the first and second band respectively. Modified...
A compact CPW-Fed CRLH metamaterial antenna is designed and developed in this paper. The design is based on a symmetric single layer CPW-Fed structure in which signal patch is connected to the CPW ground planes by introducing a strip. Proposed antenna shows two modes at 1.70 GHz and 5.30 GHz respectively. In addition to that this antenna offers excellent dipolar and omnidirectional radiation pattern...
In this paper a compact planar CPW-fed metamaterial antenna with closed ring resonator (CRR) has been proposed. It is observed that by employing CRR into the structure an extra band is found at 2.17 GHz (n = −1 mode) and therefore electrical size of the antenna is decreased significantly. CPW- feed is introduced to enhance the bandwidth and radiation efficiency of proposed antenna. This antenna is...
In this paper, a compact CPW-fed complimentary half split ring resonator (CHSRR) antenna for WLAN is proposed. The proposed antenna shows compact size (due to ZOR) with dimensions 0.18λ0× 0.15λ0× 0.03λ0 at center frequency of 5.57 GHz. Impedance Bandwidth of 14% (S11 < −10 dB) from 5.17–5.95 GHz has been achieved with monopole-type radiation pattern in xz-plane and dipolar-type radiation pattern...
