Abstract :
In this letter, the parasitic mode conversion that occurs at microstrip to stripline transitions is analyzed through electromagnetic simulations and an equivalent circuit including the parallel-plate impedance. It is shown that the excitation of plate modes can significantly impact transmission and crosstalk parameters, and that mitigation of mode conversion by the utilization of return vias is feasible.
