Nowadays, millimeter-wave systems are being a key factor to develop wide band applications. In this paper, a directional coupler in millimeter-wave band using dielectric overlay is presented. This leads us to technology aspects, in directional coupler design, are key points to achieve the proper response of the circuit. The coupler proposed in this paper covers the 15{45 GHz band and its response has 15-dB coupling-level, 1-dB coupling-ripple and a re°ection coe±cient better than 10 dB.
