Patent Images
1. A broadband multi-loop antenna mountable in a mobile communication device having a chassis (100), comprising:
- a conductor assembly electrically connected to the chassis (100) and including a plurality of loops each starting at a common feed point (1) and ending at respective grounding points; and
means for mounting the conductor assembly thereon,wherein at least one of the loops comprises at least one conductive branch having one end connected to a predetermined location of the loop other than the grounding point of the loop and the other end open; and
wherein the loops comprise a first loop (10) having a grounding point (2), and a second loop (20) having a grounding point (3), the first and second loops (10,20) having a common conductor (5), and either (i) the first and second loops (10,20) being located on the same side of the common conductor (5) or (ii) the grounding point (2) of the first loop (10) and the grounding point (3) of the second loop (20) being located on the same side of the common feed point (1).

Abstract
A broadband multi-signal loop antenna used in a mobile terminal comprises a conductive part and a supporter supporting the conductive part. The said conductive part is electrically connected to the substrate of the mobile terminal. The said conductive part includes at least two signal loops which start at a common feed point and end at the ground points, wherein at least two signal loops each has a ground point and the ground points are located at different physical positions. The antenna can resonate at multi-band.
