A compact rat-race circuit consisting of planar circuits is presented in this paper. The prototype is fabricated at 1GHz, and the propagation characteristics and reflection characteristics of each port are measured. The measurement results agreed well with those of the theory. The dimensions of the circuit are approximately 21mm×25mm.
