ABSTRACT:
In a microwave delay equalizer for an input signal of a microwave frequency having an inevitable delay distortion, a directional coupler and a pair of resonators are placed, respectively, on a center area of a conductive base member and on those side areas thereof which lie on both sides of the center area. The coupler comprises a pair of distributed-constant elements electromagnetically coupled to each other either with an air space or a dielectric plate interposed therebetween and to the respective resonators to derive from the input signal supplied to one of the elements a delay equalized output signal in the other element. Each element has a length equal to an odd multiple of a quarter wavelength of the signal travelling therealong. Each resonator consists of at least one resonance piece. For a dielectric base member, the elements possessed preferably of corrugated sides opposing each other with a zigzag-shaped area of the center area left therebetween and the resonance pieces are formed directly on the center and side areas by conductive patterns together with a pair of conductors which are connected to one end each of the resonance pieces and are to be grounded.
