Abstract: Dynamic tuning method for a specific absorption rate (SAR) is provided. The dynamic tuning method is applied to user equipment (UE). The dynamic tuning method may include the following steps: the UE may determine the back-off value corresponding to the current antenna state; and the UE may tune the conducted power of the radio frequency (RF) circuit of the UE based on the back-off value.

Abstract: The invention provides method and apparatus augmenting functionality of an antenna-in-module (AiM) of a user equipment (UE) to proximity detection (and more) besides wireless communication. The AiM may comprise a radiator set and a channel circuit set. The radiator set may comprise one or more radiators, and the channel circuit set may comprise one or more channel circuits. The method may comprise: causing a first subset of the channel circuit set to transmit outgoing electromagnetic (EM) waves by circular polarization of a first rotation sense, causing a second subset of the channel circuit set to receive incoming EM waves by circular polarization of a second rotation sense different from the first rotation sense, accordingly obtaining one or more received detection signals, and executing the proximity detection according to the one or more received detection signals.

Abstract: The invention provides an antenna subsystem with improved radiation performances. The antenna subsystem may comprise an antenna-in-module (AiM), an auxiliary structure being conductive, and a support structure being nonconductive and disposed between the AiM and the auxiliary structure. The AiM may comprise a base, and one or more radiators being conductive. The antenna subsystem may provide a spherical coverage by a combination of a first component of gain and a second component of gain. The auxiliary structure may be insulated from the one or more radiators, and may be configured for orienting a radiation pattern of the first component of gain and a radiation pattern of the second component of gain to two different directions respectively; and/or, causing the spherical coverage provided by the antenna subsystem to be broader than a spherical coverage provided by the AiM alone.
