Abstract :
Two reduced size hybrid type rat-race coupler designs are presented. By using two kinds of T-type equivalent circuits replaced the transmission lines used in rat-race coupler and employing the coupled line structure, we achieved reduce size rat-race designs. Two prototypes designed at 2.45GHz are designed, simulated, fabricated on FR4 substrate and measured. The simulated and measured results show a good agreement in the frequency range of interest.
