Abstract
An antenna device is disclosed, which is intended for a portable radio communication device. The communication device includes a signal generating component having a signal output, said output defining a signal generating circuit impedance. The antenna device includes a substantially planar conductor having an associated impedance and preferably extending in a first dimension greater than approximately one-quarter of a predetermined operational wavelength. The antenna device further includes a matching network which is coupled to the signal generating output. The matching network having a substantially planar dielectric substrate and a conductive meander element and a conductive trace element, wherein said matching network transforms the impedance of the signal generating component to approximate the impedance of the planar conductor element.
