Abstract

The invention discloses a satellite-borne curved-surface multi-beam array antenna double-layer multi-directional module blind-mating frame structure, which relates to the field of satellite-borne multi-beam array antenna structure design and comprises an inner-layer frame, an outer-layer frame, a central beam antenna, a surrounding beam antenna and a mounting base body. The inner-layer frame is mounted on the mounting base body, and the central beam antenna is mounted above the inner-layer frame; the outer-layer frame is installed above the central beam antenna, the upper portion of the outer-layer frame is of a plane opening structure to give way to the central beam antenna, and the surrounding beam antennas are installed on the outer-layer frame. According to the invention, the electrical blind-mating interconnection can be completed while the antenna array elements are installed in multiple directions along the circumferential surface, the space of each layer in the frame can be utilized in a limited manner, and the requirement of maximization of the module loading capacity is met, so that the design requirements of miniaturization, operability and high reliability of the satellite-borne curved-surface multi-beam array surface antenna are met.
