Abstract :
In this paper, based on the performances analysis of bent couplers, An improved 3dB three-section slot-coupled bent coupled operating over a bandwidth from 0.6 to 1.8 GHz is presented. The proposed couplers are constructed by two symmetrical three-section microstrip lines, coupled by slot between them. The simulated and measured of S-parameters and phase imbalance results are presented with good agreement.
