Dual Band 9-Shaped Graphene-Film Patch Antenna for 5G Applications

Abstract

In this paper, a 9-shaped planar dual-band graphene antenna for 5G application is presented. The 9-shaped graphene-film is used as radiation patch with microstrip fed line. The proposed antenna satisfies the requirement of -10dB reflection coefficients for the impedance bandwidth of LTE2500MHz and WiMAX3.5GHz bands. The simulated gain for lower and upper band is 1. 85dB and 2. 4dB respectively. The radiation efficiencies are 82% and 77% for lower and upper band respectively.
