Development of Ku Compact Broadband 1×4, 1×8 and 1x16 Power Dividers with SIW Optimized Chamfered Bends

摘要

In this paper, compact broadband 1 ×4, 1×8 and 1x16 SIW power dividers based on SIW chamfered right bend operating in Ku-band frequency and that provide equal power split in all output ports are presented. Substrate Integrated Waveguide is an artificial waveguide synthesized and constructed with linear arrays of metalized via-holes in the same substrate used for the planar circuit. In this paper SIW H plane chamfered right bend and dividers are simulated and optimized using 3D FEM simulator HFSS, also the frequency responses as the return losses, transmission coefficients and the field's distribution are exposed. The concept is validated by simulations using CST Microwave Studio. These broadband SIW power dividers can be used widely in microwave and millimeter-wave circuits and system.
