Meta-material inspired monopole antenna for LTE/bluetooth/Wi-max subsystems

Abstract

A Meta-material inspired hex-band antenna for LTE/ Bluetooth / Wi-Max subsystems is presented in this paper. The antenna presented is having dimensions of 52×33mm2 printed on FR4 substrate of thickness 1.6mm. The proposed antenna achieved six resonance peaks at 3.1/4.1/6.4/6.8/8.4/12.5 GHz. The Split Ring Resonator introduced act as a part of defected ground structures, which improve the current directions. The final antenna proposed has circular polarization at frequencies 2.2/2.3/5.2 GHz. The presented antenna has a peak gain of 4.2dB.
