BILAYER SHORT SLOT COUPLER, BUTLER MATRIX FEEDER CIRCUIT AND PHASED ARRAY ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide a bilayer short slot coupler capable of simplifying a device configuration for performing switching in a two-dimensional direction, and a butler matrix feeder circuit.SOLUTION: A bilayer short clot coupler 10 comprises: an input part 10A in which four input ports 11-14 each for inputting an input signal are disposed in a matrix shape of 2×2 layers; an output part 10B in which four output ports 15-18 each for outputting an input signal are disposed in a matrix shape of 2×2 layers; and a coupling part 10C that is disposed between the input part 10A and the output part 10B and has a cross-sectional shape P that generates a multi-mode electromagnetic field. The coupling part 10C changes an output form of a signal from the output part 10B in a two-dimensional manner relatively to an input signal that is inputted from any one of the input ports 11-14.SELECTED DRAWING: Figure 1
