The invention discloses an integrated tile active phased-array antenna. The antenna comprises an array antenna layer, a heat dissipation cavity, a radio frequency layer, a transition layer, a power supply and control layer and a cover plate layer. A plurality of first slots are formed in one side, close to the transition layer, of the radio frequency layer, first radio frequency chips are arrangedin the first slots, a plurality of second slots are formed in one side, close to the transition layer, of the power supply and control layer, and second radio frequency chips are arranged therein; acontrol device is arranged on one side, close to the cover plate layer, of the power supply and control layer and used for power supply and signal control; the transition layer plays a role in radio frequency signal transition and radio frequency isolation; the array antenna layer is electrically connected with the radio frequency layer at high frequency through a first radio frequency connectionstructure arranged on the heat dissipation cavity; the radio frequency layer is electrically connected with the power supply and the control layer at high frequency through a second radio frequency connection structure arranged on the transition layer; the cover plate layer is electrically connected with the power supply and control layer. According to the antenna, the multi-channel, multi-polarization or multi-frequency multifunctional high-integration integrated design is achieved, the overall size is small, the weight is light, and the thickness is small.
