Abstract: An adaptive receiver for a high output power system includes a band-pass filter that receives a transmission signal output from a transmitter and outputs a transmission signal for canceling a leakage signal from which noise has been removed, and a leakage signal canceller that includes a first metal layer through which the transmission signal for canceling the leakage signal flows and a second metal layer through which a transmission leakage signal by the transmission signal flows, in which the first metal layer and the second metal layer are disposed adjacent to each other to generate a coupling effect, the transmission leakage signal for canceling the leakage signal flows in a reverse direction to a direction in which the transmission leakage signal flows, and the transmission leakage signal is canceled.
