Abstract (en)
An antenna, and an associated methodology, for a portable radio device, such as a mobile station capable of operation at a plurality of frequency bands spread across a wide range of frequencies. The antenna includes a dielectric substrate and a monopole disposed about the substrate. The monopole includes a first end having a feed point connection and is folded in a serpentine manner about at least three planar surfaces of the substrate. A first patch element improves matching at a first frequency band, extends from the monopole. A second patch element improves matching at a second frequency band, extends from the monopole and is proximate to the feed point connection. A third patch element improves matching at a third frequency band, extends from a second end of the monopole, opposed to the feed point connection.
