A millimeter-wave filtering coupler based on LCP material with multi-layer suspended coplanar waveguide is proposed. Three parallel-coupled lines are used to feed each port of the artificial transmission line coupler, so that the whole structure achieves the effect of wideband filtering coupler. The proposed filtering coupler centers at 33GHz, achieving a wideband from 25.6 GHz to 40.5 GHz (45.2 % ) with a return losses of lower than -15 dB, and a phase imbalance of less than ±6°.
