ABSTRACT:
Disclosed is a rotating joint used in radars to transmit electrical signals on several channels between a rotating antenna and a fixed support. The pass-band of the matched and coupled circuits of each channel is substantially improved by making these circuits on concentric, circular rings which have metallic ground strips deposited on both faces, said strips being connected by metallized holes, and metallic strips of coils connected by the facing sections of the rings.
