Multiple-element antenna with parasitic coupler
First Claim
1. A multiple-element antenna for a multi-band wireless mobile communication device, comprising:
- a first antenna element having a first operating frequency band and coupled to a first transceiver in the multi-band wireless mobile communication device that communicates at the first operating frequency band;
a second antenna element having a second operating frequency band and coupled to a second transceiver in the multi-band wireless mobile communication device that communicates at the second operating frequency band;
wherein the second antenna element is physically separated from but positioned adjacent to the first antenna element to thereby electromagnetically couple the first and second antenna elements; and
a parasitic coupler physically separated from both the first and second antenna elements but positioned adjacent to both to thereby electromagnetically couple the parasitic coupler to the first and second antenna elements.

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, and a parasitic coupler positioned adjacent the first antenna element and the second antenna element. 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.
