MULTIPLE-ELEMENT ANTENNA WITH PARASITIC COUPLER

摘要

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 eleme nt 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 couple r when the multiple-element antenna is operating in the first or second operating frequency band. The first and second antenna elements are configur ed to be connected to first and second transceivers in a wireless mobile communication device in an alternate embodiment.
