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.

The split ring resonator (SRR) loaded periwinkle flower (PWF) shaped fractal antenna for multiband applications are presented. The CPW‐Fed antenna consists of SRR, which is fixed on the back side of the FR4 and periwinkle petals which are etched on top of the FR4 i.e., on the circular patch. The periwinkle flower‐shaped irregular fractal patch is erected on the substrate whose dimensions are Ws × Ls × h mm3 and the ground is also modified (MG) to achieve multiple frequency bands covering 3.476 GHz at S‐band, 4.844 GHz at C‐band, 8.3 GHz also 10.28 GHz at X‐band, 17.76 GHz and at Ku‐band. Parametric analysis and measured antenna device results are also presented.

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.
