RF partitioning network for array antenna.

摘要

Lightweight mechanical structure to support large dimension array antennae, designed so as to offer two horizontal dividers (1), one positioned in the upper part and one in the lower part of the mechanical supporting element. Such supporting element is therefore made of a central panel (2), also used as the ground plane of the two horizontal dividers, closed at its sides by a frame of extruded aluminium (3) (4) partly machined (3) to form an interface towards the external circuits. The components of the system are assembled by means of structural adhesives. The purpose of the device is to feed the radiating elements of an array type of antenna. The main advantages offered by this new solution are the following: - Low manufacturing cost due to the reduced number of tooling and finishing steps required; - good planarity and rigidity proprieties compared to the overall dimensions; - good weight reduction. t
