Abstract

A multiple-element antenna for a multi-band wireless mobile communication device is provided. The multiple-element antenna includes a first antenna element, a second antenna element positioned adjacent the first antenna element such that the second antenna element electromagnetically couples to the first antenna element, and a parasitic coupler positioned adjacent the first antenna element and the second antenna element for enhancing electromagnetic coupling between the first antenna element and the second antenna element through the parasitic coupler. In one embodiment, the first and second antenna elements have respective first and second operating frequency bands, and electromagnetically couple with each other and with the parasitic coupler when the multiple-element antenna is operating in the first or second operating frequency band. The first and second antenna elements are configured to be connected to first and second transceivers in a wireless mobile communication device in an alternate embodiment.
