Metamaterial Inspired CPW Fed Multiband Antenna for IOT Applications

Abstract

This paper presents a multi-band coplanar waveguide (CPW) fed antenna of size 47mm × 43
mm x 1.6mm with hexagonal patch implementing on a FR4 substrate with permittivity 4.6 and
loss tangent of 0.001 based on metamaterial structure. Hexagonal ring technique is used to
create multiple band of required frequency. Metamaterial structured antenna covers a
frequency of 1.8 GHz, 2.4 GHz, 3.5 GHz and 5.2 GHz. It is suitable for the future 5G Internet
of Thing (IoT) portable applications, WiMAX, Wi-Fi/Bluetooth applications. This antenna is
designed and simulated results of return loss, voltage standing wave ratio (VSWR), radiation
pattern using Ansys HFSS version 16.
