Abstract

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.

Description

technical field [0001] The invention belongs to the structural improvement of a phased array antenna module, and in particular relates to a phased array antenna module integrating electromechanical and heat. Background technique [0002] Phased array antennas use inertial beams for electronic scanning, which has unique advantages compared with ordinary mechanical scanning. Since the 1960s, phased array antennas have been used in various tactical radars, such as search, guidance, and fire control. and guidance radar. Some civilian radars, such as microwave landing radars in air traffic control systems, and even weather radars are gradually adopting phased array antenna technology. [0003] In recent years, with the rapid development of semiconductor technology, including crystal power transistors, integrated circuits, signal processing, data processing and computer technology, it has greatly promoted the development of phased array antenna technology and reduced the cost of ...
