A millimeter‐wave slow‐wave transmission line (T‐line) implemented with Si‐benzocyclobutene (Si‐BCB) technology is modeled in this paper. An artificial neural network (ANN) is applied to map the numerical relationship between the geometric parameters of the slow‐wave T‐line and its S‐parameters. The Levenberg–Marquardt algorithm and Gradient Descent Back‐Propagation optimization method are used during ANN training process. A 30‐GHz coupler based on the proposed slow‐wave structure is fabricated and measured. The ANN results, electromagnetic (EM)‐simulated results, and measured results are consistent with one another.
