摘要： An apparatus and method for removing a transmission leakage signal are provided. The apparatus includes: a directional coupler connecting an antenna to a transmission path and a reception path; and a reflection coefficient adjustment unit outputting a reflection signal to the reception path, the reflection signal having the same amplitude as and opposite phase to a first transmission leakage signal generated from the transmission path and input to the reception path and a second transmission leakage signal reflected by the antenna and input to the reception path.
