Embodiment Construction
[0016] The structure of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0017] Such as figure 1 and 2 As shown, a light-weight cable-membrane microstrip phased array antenna structure includes a radiation layer copper-clad film 1, a stratum copper-clad film 2, a rigid frame 3, and a cable net 4. The radiation layer copper-clad film 1, the formation copper-clad film 2 and the cable net 4 are all fixedly arranged on the rigid frame 3; the rigid frame 3 is a frame structure, the cable net 4 is located in the middle of the rigid The copper film 2 is respectively located on the upper and lower sides of the cable net 4 in the rigid frame 3 . Grid nodes 5 are arranged on the cable net 4, and the grid nodes 5 are braided nodes for preventing off-line, and are respectively bonded to the copper-clad film 1 of the radiation layer and the copper-clad film 2 of the stratum. The upper surface of the radiation layer ...

Abstract
The invention relates to a light-weight cable film microstrip phase control antenna structure. A radiation layer copper-clad film, a ground layer copper-clad film and a cable net are all fixedly arranged on a rigid framework; the rigid framework adopts a framework structure, the cable net is positioned in the middle part of the rigid framework, and the radiation layer copper-clad film and the ground layer copper-clad film are positioned on the upper and lower surfaces of the cable net in the rigid framework respectively; the cable net is provided with a grid node, and the grid node is glued with the radiation layer copper-clad film and the ground layer copper-clad film separately; a copper foil layer is arranged on the upper surface of the radiation layer copper-clad film to be used as a copper foil radiation unit; and a ground layer copper foil is arranged on the upper surface of the ground layer copper-clad film. Compared with the conventional microstrip phase control antenna, the light-weight cable film microstrip phase control antenna can obviously lower surface density, realize a lighter weight, and can satisfy the quality demand of a large-dimension and ultra-large-dimensionC frequency band microstrip phase control antenna and the thermal deformation requirement of a microstrip phase control array at the frequency band of 5.8-10GHz.
Description
technical field [0001] The invention belongs to the technical field of aerospace microstrip phased array antennas, and relates to a light cable-membrane microstrip phased array antenna structure. Background technique [0002] The space solar power station consists of satellites, giant solar cell arrays, super large space microwave transmitting antennas and ground giant microwave receiving antennas. The electric energy collected by the solar cell array is transmitted to the ground by the space microwave antenna in the form of microwaves, and after being received by the giant microwave antenna on the ground, it is transmitted to the ground grid for use. Space solar power plants are expected to solve the energy crisis and environmental pollution problems caused by thermal power generation, so they have become a research hotspot in various countries. However, due to the limitations of the current technical level and funding sources, most of the research is in the research stage...
