“…These materials can be realized by using metallic , Split Ring Resonators (SRRs) and the combination of both Vias and SRRs respectively. The characteristics of SRRs and CSRRs have been studied and analyzed by several groups [4][5][6][7][8][9][10][11][12][13][14][15][16][17]. By applying the concept of duality to the negative permeability nature of SRR, the negative permittivity nature of CSRR can be obtained.…”

In this paper, a novel compact microstrip patch antenna is proposed for Wi-Fi and WiMAX bands. To achieve miniaturization the dimensions of the square radiating patch are chosen with reference to the high frequency band (3.3 GHz). The dual band is achieved by loading a Complementary Split Ring Resonator (CSRR) into the radiating patch. The left handed nature of the CSRR is the cause for low frequency band (2.4 GHz). To improve the return loss bandwidth and axial ratio bandwidth at upper band the fractal concept is introduced along the edges of the square patch. Thus a low volume dual band antenna is simulated using HFSS. A comparison with measured data is also presented. The fabricated antenna is found to be occupying 25% less volume (with reference to 2.4 GHz) than existing antennas which is mainly due to the blending of the two recent concepts 'metamaterials and fractals'.

“…In [9-13], single band and dual band antennas are designed by etching CSRR from the ground plane. In [14][15][16], dual band and single band antennas are designed by using MNG materials. In [17], the combination of both DNG and Double Positive materials is used to get dual band antenna.…”

“…The number of iterations calculated through Iterated Function System (IFS) is given by Equation (1) [3]. L = n n + 1 (1) where n = number of iterations, and L = Iteration Function System (IFS). Self-similar properties of fractal are the main cause of multiband properties of the antenna.…”

Abstract-In this paper, a metamaterial loaded square-shaped fractal antenna with two iterations is presented and discussed. A metamaterial loading consists of split ring resonators (SRRs) which enhances the bandwidth of the antenna keeping the dimensions and size of the antenna same. The square-shaped fractal antenna, which is in the form of three concentric rings, was simulated and fabricated, and the results were shown and discussed. The antenna resonates at three distinct frequency bands 4.3719 GHz, 7.7437 GHz and 10.6374 GHz with the gains of 1.1974 dB, 4.2745 dB and 4.7233 dB, respectively for resonant frequencies. The bandwidths for the antenna are 185 MHz, 198 MHz and 386 MHz for distinct resonant frequencies. The antenna is fabricated using an FR-4 substrate, and the measured resonant frequencies are 4.08 GHz, 7.545 GHz and 10.24 GHz. In metamaterial loading condition, the antenna resonates at 4.0105 GHz, 6.8474 GHz and 8.0632 GHz with bandwidths of 636 MHz, 347 MHz and 1.33 GHz at resonant frequencies. The appreciable bandwidth is achieved in such a small antenna without changing dimensions and size of the antenna. The simulated, experimental results and comparison are also presented in this paper. The results show that the proposed method can be used to design high bandwidth and compact fractal microstrip patch antennas without increasing dimensions.

Abstract-In this paper, a novel CPW-fed triple band metamaterial inspired antenna with modified ground plane is presented. The metamaterial inspired structures such as split ring resonator (SRR) and non bianisotropic complementary split ring resonator (NBCSRR) are embeded in this antenna for triple band operation. The proposed antenna with a compact size of 25 × 31.7 × 1.6 mm 3 is fabricated and tested. The antenna with good radiation characteristics is suitable for WIMAX, C band and WLAN applications. The simulated and measured results are discussed and are in good agreement with each other.
