Abstract
An antenna system includes co-located active steering antennas implemented in a bottom portion of a wireless communication device designed for positioning near a user's mouth or chin. The co-located active steering antennas are each configured to steer a radiation pattern of the respective antenna, and can be further configured for active band switching and/or active impedance matching. These co-located active steering antennas can be used independently, or in a multi-input multi-output (MIMO) configuration. In addition, the antenna system is capable of antenna unit selectivity, which includes the ability to select one of the co-located antennas with the lowest head and hand loss for use, while disabling the antenna with the highest loss attributed to hand/head loading.
