WAVEGUIDE POWER SYSTEM OF PHASED ANTENNA ARRAY Russian patent published in 1996 - IPC

FIELD: microwave devices, radio equipment. SUBSTANCE: device has input power splitter connected to axis-symmetrical multichannel power splitter and section of ladder-type power splitters. Input power splitter uses herringbone splitting circuit set up of waveguides T-junctions. Axis-symmetrical multichannel power splitter is made as transition from rectangular H₁₀- wave guides to coaxial H₀₁.-wave guide. Each ladder-type power splitter in section of ladder-type power splitters uses herringbone type circuit arrangement set up of rectangular waveguides. Input rectangular waveguides are arranged over circumference and connected to output rectangular waveguides of axis-symmetrical multichannel power splitter. Input power splitter is placed inside axis-symmetrical multichannel power splitter which is installed in section of ladder-type power splitters. Section of ladder-type power splitters may be assembled of wedges with grooves on side edges. Output waveguides of axis-symmetrical power splitter may have different sectional areas. EFFECT: enlarged functional capabilities. 5 cl, 10 dwg
