Abstract
A compact sized embedded, multiband, multi-standard, interoperable antenna for portable devices used in wireless applications is provided. The antenna design includes an asymmetrical structure provided on a double-sided printed circuit board. The asymmetrical structure covers both the ultra-wideband and the wireless local area network band. The asymmetrical structure provided on the front side of the printed circuit board is a primary radiator with a supplement strip radiator, whereby the bottom of the primary radiator is close to the vertical ground plane and fed by a probe extended from a coaxial line. The asymmetrical structure on the front side provides a well-matched bandwidth covering the ultra-wideband band of 3.1 GHz to 10.6 GHz. A second supplement strip is provided on the backside of the printed circuit board which provides the second resonance at the 2.4 GHz wireless local area network band.
