A Metamaterial Inspired Tapered Patch Antenna for WLAN/WiMAX Applications

This paper presents a metamaterial inspired antenna with tapered patch for operating in 2.5 GHz, 3.5 GHz, 4.6 GHz, and 5.8 GHz frequencies of WLAN/WiMAX applications. The resonant modes obtained by the implementation of CSRR and modified patch structure. The negative permittivity characteristics of the CSRR is discussed along with its equivalent circuit. The proposed antenna is also fabricated using the low cost FR4 Epoxy substrate with dielectric permittivity of 4.4, height of the substrate is 1.6 mm and loss tangent 0.02 and measured for the validation of the design. The proposed antenna achieved gains of 6.06 dBi, 12.1 dBi, 15.1 dBi, 4.6 dBi in 2.5 GHz, 3.5 GHz, 4.6 GHz, and 5.8 GHz respectively. Stable radiation patterns were also observed in the same operating regions.
