摘要：

This letter presents a wideband planar crossover for application in circuits based on substrate integrated waveguide (SIW). The proposed structure uses SIW to grounded coplanar waveguide (GCPW) transition, which facilitates crossing of two waves in the same substrate without considerable leakage. The coplanar waveguide (CPW) is used in the core part of this crossover, which provides a high isolation. GCPW lines are tapered and connected to CPW lines, resulting in a wideband matching. The proposed design has been verified via full wave electromagnetic simulation and experimental test. The crossover dimensions with SIW excitation is 40 mm x 40 mm and its isolation across 9-18 GHz band is more than 20 dB.
