Patent ID: 7777684

Claim:
A multi-band slot-strip antenna comprising: a planar conductive layer comprising a conductive region and a non-conductive region, the conductive region and the non-conductive region together defining: a first slot-strip structure comprising a signal feed portion; a second slot-strip structure coupled to the first slot-strip structure, the second slot-strip structure comprising a first signal grounding portion; and a third slot-strip structure coupled to the second slot-strip structure, the third slot-strip structure comprising a second signal grounding portion, the signal feed portion being coupled to the radio transceiver section, the second signal grounding portion being distinct from the first signal grounding portion, wherein the slot-strip structures each have a substantially U-shape, each said U-shaped slot-strip structure comprises a pair of arms, abuse portion joining together the arms, and a slot extending between the arms, the signal feed portion and the grounding portions are each disposed on one arm of the respective slot-strip structures, another arm of the first slot-strip structure is common with the one arm of the second slot-strip structure, another arm of the second slot-strip structure is common with another arm of the third slot-strip structure, and the second signal grounding portion is provided on another arm of the third slot-strip structure.
