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: A beam management method of an electronic device includes transmitting a detecting signal, receiving a reflecting signal of the detecting signal, determining blocked antennas of an antenna array of the electronic device according to the reflecting signal, and exciting only unblocked antennas of the antenna array. This will improve the radiation efficiency of the antenna array.

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.

Abstract: A communication device for detecting an object includes a power module, an antenna array, a first sensor pad, a second sensor pad, and a control unit. The antenna array is excited by the power module, and is configured to provide a first beam group and a second beam group. The first sensor pad is disposed adjacent to the first side of the antenna array. A first capacitance is formed between the first sensor pad and the object. The second sensor pad is disposed adjacent to the second side of the antenna array. A second capacitance is formed between the second sensor pad and the object. The control unit controls the power module according to the first capacitance and the second capacitance, so as to selectively apply at least one power backoff operation to the first beam group and/or the second beam group.
