MULTICHANNEL POWER DISTRIBUTOR Russian patent published in 2019 - IPC H01P5/12 

FIELD: radio engineering; electronics.

SUBSTANCE: invention relates to superhigh-frequency equipment and can be used in various radio devices, for example, for formation of amplitude-phase distribution in transceiving active phased antenna arrays with two independent beams. Multichannel power distributor comprises the first dielectric substrate, on one side of which the grounding base is fixed, and on its other side – input strip conductor and output strip conductors. Second dielectric substrate is fixed on the other side of the grounding base. N-1 Wilkinson dividers are connected in parallel circuit on first dielectric substrate, and N-1 Wilkinson dividers on the second dielectric substrate are connected in a parallel circuit and are offset with respect to Wilkinson dividers of the first dielectric substrate. To eliminate radiation losses and associated parasite resonances while maintaining the possibility of forming two independent amplitude distributions, input and output strip conductors are located on both the first and second dielectric substrate. Earthing base is made in form of foil layer, and outer sides of dielectric substrates are closed by layers of dielectric material and outer screening layers of foil, wherein all strip lines on two sides at a distance equal to two widths of the strips are enclosed by rows of metallized small-diameter holes connecting the grounding base and outer shielding layers of the foil. Inlets and outlets of multichannel power distributor through metallized holes are brought to contact pads located on upper shielding layer of foil.

EFFECT: invention provides avoiding radiation losses and associated parasite resonances while maintaining the possibility of forming two independent amplitude distributions and increasing isolation by outputs.
