The invention belongs to structure improvement of a phased-array antenna module, and particularly relates to a machine-electric-heat-integrated phased-array antenna module. The machine-electric-heat-integrated phased-array antenna module comprises horizontal polarization waveguide antennas, perpendicular polarization waveguide antennas, T/R assemblies, delay lines, a micro-strip power divider, a coupled feeding network, a module-level beam control part and a module-level power source. The horizontal polarization antennas and the perpendicular polarization antennas are arranged on an upper layer and a lower layer in an array mode, wherein the horizontal polarization antennas are located on the upper layer, and the perpendicular polarization antennas are located on the lower layer; the horizontal polarization antennas and the perpendicular polarization antennas are arranged in a staggered mode, grooves with downward openings are surrounded by the bottom walls of the horizontal polarization antennas and the side walls of the perpendicular polarization antennas, and the T/R assemblies are installed in the grooves. According to the machine-electric-heat-integrated phased-array antenna module, an antenna array is composed of the horizontal polarization waveguide antennas and the perpendicular polarization waveguide antennas, the grooves are formed in the back face of the antenna array, the T/R assemblies and the delay lines are put into the grooves, the phased-array antenna module is more compact in structure, and the thickness of the module is also reduced along with the phased-array antenna module structure.
