PROBLEM TO BE SOLVED: To provide a synthesis distribution circuit for easy holding of circuit components, to be constituted in a small area and to be used in wide frequency band by arranging each nonradioactive dielectric line to be capable of electromagnetically coupled with a resonator. SOLUTION: Four dielectric strips 3 are arranged with respect to ports (1) to (4) between upper and lower conductor plates, and a dielectric resonator 8-1 is arranged at the center so that distances between it and four dielectric strips 3 become d1 , d2 , d3 , d4 from respective lines of each port. Since each port is arranged with d1 to d4 with respect to the resonator 8-1, when d1 ≠d2 , d3 , d4 ; d2 ≠d3 , d4 ;3 ≠d4 , signal power supplied, for example, from the port (1) is distributed unevenly to each of the ports (2) to (4) with intensities which are proportional to the distance d2 , d3 , d4 . Conversely, when signals with the same frequency are inputted from the ports (2) to (4), power output with the intensity as the sum of the signals from each of the ports which are synthesized with the intensity in proportion to d2 , d3 , d4 is outputted to the port (1). |
