Abstract

PURPOSE:To provide a coupling line from loose coupling to close coupling with constitution obtained by arranging a microstrip line and slot line on each of one side of a substrate to permit them to couple each other. CONSTITUTION:A conducting layer 12 is formed entirely over one surface of the insulating substrate 11 and on the conducting layer 12 a slot line 16 for coupling is formed. Slot lines 17-20 perpendicular to the slot line 16 are formed, being named as input/output ports P1-P4. On the other side of the substrate 11 a microstrip line 21 is formed oppositely and in parallel to a slot line 16 for coupling. Extension parts 24, 25 of the microstrip line with length of 1/4 of wavelength to be used are formed at the outer side from branch points 22, 23 at both ends of the slot line 16, being shortened in high frequency to the conducting layer 12 at the branch points 22, 23. An input signal from the port P1 is divided to the ports P2, P3 with a phase difference of 90 deg.. By adjusting widths W1, W2, the coupling line from loose coupling to dense coupling is obtained.
