Open publisher page 32 citations

Abstract

In this letter, a simple planar monopole antenna with two operating bands for multiband mobile systems application is proposed. The proposed antenna is composed of two inverted-L branches and an open stub for impedance tuning. Both branches are resonating as quarter-wavelength monopole structures. The antenna covers the 890970-MHz and 16702350-MHz bands. A modified design for 824895-MHz and 14402180-MHz bands can be easily achieved by narrowing the widths of the lower resonant branch and the open stub. Both simulation and experimental results for the antenna characteristics are presented and discussed.
