Abstract:
1. An apparatus comprising: a ground plane having a longitudinally dipole-like resonant mode; a first antenna configured to excite the dipole-like resonant mode of the ground plane and to feed against the ground plane; a second antenna configured to feed against the ground plane; and a third antenna configured to feed against the ground plane, where the second antenna and the third antenna are each configured to cover at least one of a first, second, third or fourth frequency band; wherein said second antenna and said third antenna are substantially in the same plane and define a planar surface, the second antenna is positioned at a first corner of the planar surface, said first corner defining a first edge, the third antenna is positioned at a second corner of the planar surface, said second corner defining a second edge, and the first antenna extends from the first edge to the second edge of the planar surface.
