The invention discloses a high-power dual-frequency dual-polarization tile type active phased-array antenna, which is characterized in that a wave control circuit layer accesses a double-frequency signal and a power supply and control signal and transmits the signals to a rear layer, a feed network layer performs channel expansion on a low-frequency radio-frequency signal and transmits a high-frequency radio-frequency signal, a first radio frequency layer and a second radio frequency layer are matched with each other to carry out radio frequency processing on each radio frequency signal and transmit each processed channel signal to an array antenna layer, the high-frequency radio frequency signal is accessed to the second radio frequency layer, and the channel outputs of the two paths of polarized signals of a first radio frequency signal share one antenna radiation unit pairwise. According to the active phased-array antenna, the dual-frequency dual-polarization tile type design is realized, and the antenna h
