Embodiment
[0054] The stripline power divider in this example is made of Rogers6002 material lamination process, the conductive adhesive film is GC280, the diameter of the flexible feeder is 0.66mm, and the shell of the multilayer feeder network is made of aluminum alloy. The overall size of the four-beam multi-layer feed network is 440mm×84mm×6mm, the isolation between channels is greater than 50dB, and the isolation between beams is greater than 60dB. It has been verified that compared with the microstrip form, the thickness is reduced by 6mm; compared with the waveguide form, the thickness is reduced by 12mm, and the width is reduced by 10mm, which can meet the small size of a spaceborne four-beam phased array antenna. , High isolation requirements.
