Broadband intelligent antenna system (BIAS)
A computing device with a Broadband Intelligent Antenna System (BIAS) that supports a broadband antenna design within the device. Each broadband antenna operates over a plurality of Radio Frequency (RF) bands to cover multiple different wireless technologies with a single antenna. The BIAS may continually monitor multiple triggers capable of affecting the signal quality of the wideband antennas and may automatically switch the active antennas accordingly to select an operating configuration that provides a higher signal quality of the active antennas. Triggers may be generated when, for example, one or more antennas are being blocked by a user, there is a change in the orientation of the device, a source of electrical noise is detected, unacceptable Specific Absorption Rate (SAR) proximity is detected, and so on. The trigger-based adaptive switching from one active antenna to the other may substantially improve the overall signal quality for the multiple wireless technologies supported by the device.
