“…Split‐ring resonator (SRR) is an attractive artificially made structure based on metamaterials usually made by two rectangular or circular rings in their conventional form for making left‐hand qualification where the gaps make capacitance and strips play the inductance rule . In addition, recently various shapes of these types (SRR) of metamaterial have been used for the different application, such as making notch frequency in UWB antennas, miniaturization of the waveguides, or microstrip filters and achieving CP in slot antennas . It is a prominent technique for slot antennas making great interest due to their advantages, such as simple structure, small size, and low cost.…”

The metamaterial elements and structures have been noticed for obtaining circular polarization (CP) while developing various procedures. In this paper, we have mentioned some of these cases and compared the metamaterial loads effect on antenna current distribution. We have classified them into four categories. The first case covers patch antenna based on composite right/left‐handed method, where the metamaterial has been used for changing the current distribution in the loop form. The second case has been achieved by radome and metasurface. In the third model, the interaction between feed and metamaterial load has been considered and the last case has been made by the metamaterial load with truncated structure. The metamaterial loading has been modeled based on Nicolson‐Ross or transmission/reflection techniques for extracting the permittivity and permeability. While the microstrip slot antennas are attractive for wider bandwidth, the truncated structure can change the current for achieving CP. Here, we have studied the antenna for wireless and WiMAX applications.

Abstract-In recently developed wireless communication systems, circular polarization (CP) antennas are used for communication links to reduce the natural loss effect in receivers. Therefore, in this paper, a dual-band microstrip slot antenna based on a parallel split ring resonator with circular and linear polarization which can be used for wireless and WiMAX applications is presented. The final antenna to design is based on inspired split ring resonators (SRR) to achieve circular polarization and compact size and with special parallel form of the SRR and straight feed line. We have achieved higher bandwidth in the requested frequency range with dual-band characteristics. The final antenna has a bi-directional pattern with circular polarization at the range of 2.9-3.65 GHz and bandwidths of 2-3.6 and 3.8-4.8 GHz with VSWR < 2 for WLAN, Bluetooth and radar applications for IEEE WLAN protocol with gain of 5-6 dBi, respectively. The size of the prototype patch antenna is 40×40 mm 2 . It is designed and fabricated on an FR-4 low cost substrate with ε r = 4.4 and a thickness of 1.6 mm. It is simulated using HFSS full wave software. In addition, the experimental results are presented and compared with simulation for VSWR, radiation patterns and axial ratio. The periodic analysis has been used for extracting the metamaterial parameters.

“…Split-ring resonators (SRRs) are artificial structures, in which the relative magnetic susceptibility can become negative under certain conditions [1]. SRRs are used for the creation of artificial media with the negative [2] (the so-called metamaterials) and as elements in various filters [3,4] and aerials [5,6]. Their popularity can be explained by the relative simplicity of their construction and the presence of materials that are used for their fabrication.…”
