Multi-mode broadband antenna for 2G/3G/LTE/5G wireless communication

Abstract

A broadband dual-polarised antenna for 2G/3G/LTE/5G wireless communication is proposed. A new resonant mode is induced with parasitic resonator loaded inside the loop radiator. Wide impedance bandwidth of 72.2% for VSWR<2 (1.69-3.6 GHz) is achieved with three controllable resonant modes. Stable gain and radiation patterns are obtained over the whole band.
