Multiple-element antenna with floating antenna element

A multiple element antenna for use with a wireless mobile communication device having a transceiver and a receiver, the multiple-element antenna comprising:

• a single dielectric substrate;
• a first antenna element having a first operating frequency band, on the dielectric substrate having a feeding port connected to the transceiver and the receiver;
• a floating antenna element positioned adjacent the first antenna element to electromagnetically couple to the first antenna element and configured to operate in conjunction with the first antenna element within a second operating frequency band that is dissimilar from the first operating band, the floating antenna element on the dielectric substrate and positioned adjacent the first antenna element on the single dielectric substrate to electromagnetically couple with the first antenna element;
• and
• a feeding port connected to the first antenna element but not to the floating antenna element and configured to connect the first antenna element to communications circuitry and to exchange communication signals in both the first operating frequency band and the second operating frequency band between the multiple-element antenna and the communications circuitry.
