Integrated structural design of a L-band multi-beam phased array antenna for satellite

A L-band multiple-beam phased array antenna with integrated structural design for satellite usage is described in this paper. By using the integrated design, the height of the filters and the LNA modules are reduced, and all the radiating elements and modules are assembled on one integral panel. Meanwhile, a solder-less junction structure is developed between the radiating elements and the filters. In this way, it is possible to realize the miniaturization and lightweight of the antenna.
