Patent ID: 8730110

Claim:
A mobile communication device comprising: a single planar dielectric substrate having a major surface in a first plane, a number of sides extending from edges of the major surface in planes different to said first plane, the sides and the major surface intersecting to form at least a first corner and a second corner, a plurality of antennas each having a plurality of radiating conductive strips, each antenna comprising the plurality of radiating conductive strips configured in a meander pattern and the radiating conductive strips folded to lie in at least the plane of said major surface and a plane of one of said sides, wherein a first antenna of the plurality of antennas is disposed at the first corner of the dielectric substrate; a second antenna of the plurality of antennas is disposed at the second corner of the dielectric substrate opposite the first corner, and a third antenna of the plurality of antennas is disposed at a corner opposite the first antenna and diagonal with respect to the position of the second antenna; a plurality of feed ports, wherein a first feed port is coupled to the first antenna, a second feed port is coupled to the second antenna, and a third feed port is coupled to the third antenna; and a plurality of ground pins, wherein a first ground pin is coupled to the first antenna and positioned in a vertical coordinate direction with respect to the first feed port; a second ground pin is coupled to the second antenna and positioned in a horizontal coordinate direction with respect to the second feed port, and a third ground pin is coupled to the third antenna and positioned in a horizontal coordinate direction with respect to the second feed port.
