MULTIPLE-CHANNEL WAVEGUIDE SPLITTER Russian patent published in 2000 - IPC

FIELD: microwave equipment. SUBSTANCE: device is designed as N directed couplers, which share single trunk waveguide, and N branch channels, which are oriented at angle with respect to axis of trunk waveguide and are located on both of its wider walls. One of wider walls of each branch channel shares piece of wider wall of trunk waveguide and contains oblique slots. Branch channels which adjoin to different walls of trunk waveguide are shifted with respect to one another along its axis. Outputs of branch channels are oriented in same direction, if their oblique slots are tilted with respect to the axis by 90^o > α > 0^o, and are oriented in opposite direction, if their oblique slots point in opposite direction -90^o < α < 0^o. Shift of branch channels, which adjoin to opposite wider walls of trunk waveguide, provides possibility to decrease their interaction. Alteration of their inclination angle with respect to trunk waveguide axis increases efficiency and amplitude distribution in frequency band. Position of branch channels on both wider walls of trunk waveguide increases number of splitter channels N, as well as heightens trunk waveguide and improves electric strength of device. EFFECT: decreased size, increased number of channels, possibility to alter direction of microwave power output without corners and bends, improved electric strength. 3 dwg
