Abstract：
An apparatus and method for ultra wideband (UWB) communication, using a dual band pass filter (BPF) is disclosed. The UWB communication apparatus may include a first BPF performing a first band pass filtering with respect to a UWB signal, a second BPF that has a center frequency differing from a center frequency of the first BPF, and performs a second band pass filtering with respect to the UWB signal, a first envelope detector that detects a size of a first signal filtered in the first BPF, a second envelope detector that detects a size of a second signal filtered in the second BPF, and a demodulator that demodulates a UWB signal, using the size of the first signal and the size of the second signal.
