Abstract
An internal dipole bowtie/meander antenna for a mobile terminal is capable of operating in two distinct RF bands. The antenna includes a resonating element and a ground element positioned on opposite sides of a dielectric material. The dielectric material is positioned generally perpendicular to a ground plane of the antenna. Tuning elements may be added to vary the coupling of the antenna elements to the ground plane.
