Abstract

The H‐plane folded substrate integrated waveguide (FSIW) bend with circular right‐angle in C band and X band are investigated in this article. The design formulas of the folded substrate integrated waveguide are proposed first, followed by the proper design principles of FSIW bends. Comparisons between FSIW bends and SIW bends have been made to demonstrate the validity of the design formulas. In addition, the propagation characteristics between FSIW sections and FSIW bends have been compared also, almost same propagation characteristics can be observed within. However, some fluctuations can be seen from the insertion losses of FSIW bends, implying the occurrence of the higher modes. © 2007 Wiley Periodicals, Inc.

It is observed that the radiation patterns at the lower frequencies (3 and 5.3 GHz) are not much different. Conversely, the copolarized components of the x-z plane at the higher frequencies (7.9 and 10 GHz) are relatively distorted due to the generation of the higher order modes and an offset rectan
