MULTIPLE-ELEMENT ANTENNA WITH WIDE-BAND ANTENNA ELEMENT

摘要

A multiple-element antenna for a wireless communication device is provided. The multiple-element antenna includes a first antenna element having a first operating frequency band, a second antenna element having a second operating frequency band comprising a plurality of operating frequency sub-bands, and a bandwidth enhancing parasitic element positioned adjacent the second antenna element to electromagnetically couple to the second antenna element and thereby enhance the bandwidth of the second antenna element. In one embodiment, the multiple-element antenna is fabricated on a single dielectric substrate and implemented in a wireless mobile communication device having a first transceiver and a second transceiver, with the first antenna element connected to the first transceiver and the second antenna element connected to the second transceiver.
