Abstract
Mobile communication devices with improved antenna performance are provided. A mobile communication device includes a first antenna, a ground plane, and a diversity antenna. In a mode of operation which is not a multi-antenna transmission mode, the diversity antenna is electrically coupled to the ground plane. The diversity antenna increases the electrical length of the ground plane and enhances the antenna performance of the radiating assembly of the first antenna in combination with the ground antenna and the diversity antenna.
