An antenna front-end module, method, and information handling system are adapted to the application of a direct-current (DC) bias voltage in relation to an antenna and detect a connection status of the antenna based on a sensed DC voltage. When the connection status corresponds to the antenna being connected, a first transmit power level is configured. When the connection status corresponds to the antenna being disconnected, a second transmit power level is configured. A transmit power boost can be provided such that the first transmit power level is greater than the second transmit power level. The first transmit power level can correspond to a radiative transmission mode, and the second transmit power level can correspond to a conductive transmission mode.

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.
