Abstract

PURPOSE:To make it possible to direct electromagnetic waves passing through two couplers in the same direction by allowing a passage to reach a next coupler via bent waveguides after passing by the back of the coupler, by folding the waveguide toward the back of the coupler. CONSTITUTION:An electromagnetic wave, fed from opening I of feeding waveguide 14, reaches via coupler 12a radiator 11a at a power ratio equivalent to a coupling degree and the remaining power is supplied to coupler 12b by way of bent waveguide 13a, connection waveguide 15a and bent waveguide 13b. Here, power is supplied to radiator 11b at a power ratio equivalent to the coupling degree of coupler 12b and the remaining power reaches coupler 12c by way of bent waveguide 13b, connection waveguide 15b and bent waveguide 13c. Similarly, rediators 11c and 11d are supplied with power. Further, a resistive terminator is connected to opening II of coupler 12d.
