Propagation and Band Broadening Effect of Planar Ridged Substrate-integrated Waveguide (RSIW)

摘要：

To improve the bandwidth of the SIW,a planar ridged substrate-integrated waveguide (RSIW) withA center line of cylindrical posts is proposed. Theoretical design formulas are derived. The bandwidth is defined as between the cutoffs of TE10 and TE20 modes of the RSIW. The modes are made equivalent to those of a transmission line cavity,across the transverse plane,and the cavity is loaded by A ridge of capacitive posts. Good agreements are observed between the theoretical formulas and numerical simulations.A 37％ bandwidth enhancement is achieved. Higher enhancement is possible.
