A Metamaterial based Defected Ground Antenna for IEEE P802.11ax Applications

Abstract

A sub-6-GHz / 5G spectrum band antenna for IEEE std P802.11ax is presented and analyzed in this letter. An antenna entrenched with a rectangular reflector patch with a metamaterial is designed using various substrate material and comparison is made and found that FR4 substrate material shows the better results in both simulation and in testing. The ground layer of the proposed antenna is an imposed with quarter wave defected architecture (QWDA). The proposed antenna proves its operation at Sub-6 GHz band centered at 3.5 GHz the obtained simulated return loss of proposed antenna provides evidence that less deviation in signal. The proposed geometry is validated by fabricating and testing the antenna prototype.
