Compact multi-band planar monopole antenna for LTE terminals

This article introduces a compact multi-band planar monopole antenna which is made of a driven monopole antenna and an additional strip. It is etched in a no-ground part, which is small compared to the Printed Circuit Board (PCB) size. The antenna which can operate in GSM/UMTS bands and most of LTE bands (LTE700, LTE2500, LTE3400 and LTE3600 bands) has the size suitable for mobile phones. A prototype has been realized and there is a good agreement between simulation and measurement.
