Abstract: A double-antenna radio frequency power detection circuit comprises a radio frequency transceiver, a switching module, a first power detection module, a second power detection module, a first antenna, and a second antenna. The switching module outputs a radio frequency signal received from the radio frequency transceiver, to the first power detection module or the second power detection module according to a switching signal. The first power detection module or the second power detection module respectively detects the transmit power of the radio frequency signal passing through the first antenna or the second antenna, and gives a feedback to the radio frequency transceiver.

Abstract: A capturing apparatus for an electronic device is provided in the present disclosure. The capturing apparatus for an electronic device may include a lampshade, a camera and a number of flash lamps. The lampshade may include an inner ring portion and an outer ring portion arranged concentrically. An inner rim of the outer ring portion may be connected with an outer rim of the inner ring portion. The camera may be located at a side of the lampshade and corresponding to a hollow area defined by the inner ring portion and positioned at a side of the inner ring portion away from the outer ring portion. A plurality of flash lamps may be disposed at a side of the lampshade close to the camera around a periphery of the camera and corresponding to the outer ring portion.
