摘要： An apparatus for collecting wireless is provided. The apparatus includes an antenna and a collection circuit. The antenna generates an alternating current (AC) voltage from a radio wave. The collection circuit generates a direct current (DC) voltage corresponding to the AC voltage, determines whether the DC voltage is lower than a preset value, and changes an internal impedance of the collection circuit if it is determined that the DC voltage is lower than the preset voltage.
