摘要： A wireless handheld or portable device includes an antenna system operative in a first frequency region and a higher, second frequency region that includes an antenna structure, a matching and tuning system, and an external input/output port. The antenna structure includes at least one radiating element including a connection point, a ground plane layer including at least one connection point, and at least one internal input/output port. At least one radiating element of the antenna structure protrudes beyond the ground plane layer. The antenna structure features at any of its at least one internal input/output ports when disconnected from the matching and tuning system an input return loss curve having a minimum at a frequency outside the first frequency region of operation of the antenna system. The matching and tuning system provides impedance matching to the antenna system in the first and second regions of operation of the antenna system.
