Multiple band antenna having isolated feeds

An antenna assembly for a multiple-band wireless communications device, comprising:

• a board element defining at least a ground plane and a pair of input/output RF connection points;
• and
• first and second resonator structures disposed in side by side relation a predetermined distance away from the ground plane, each of the resonator structures including a plurality of orthogonal conductive elements, each of the resonator structures including at least one conductive comer structure wherein three of the orthogonal conductive elements are coupled together, and each of the resonator structures being connected to the ground plane and to one of the pair of RF connection points.

An antenna element for a wireless communications device having a circuit board element defining a pair of input/output RF connection points and a pair of ground connection points, said antenna element comprising:

• a pair of resonator structures, each of the pair of resonator structures being connected to one of the ground connection points and to one of the RF connection points, wherein each of the pair of resonator structures includes a top surface portion and a plurality of substantially orthogonal side portions coupled to top surface portion, and wherein each of the pair of resonator structures defines at least one conductive comer structure defined by three of the side portions which are coupled together.
