Abstract :
A novel w-band ultra-wideband SIW power divider is presented. This ultra-wideband power divider utilizes substrate integrated waveguide (SIW) such that the overall size is largely reduced by half. SIW belongs to a sort of closed power splitter structure can effectively evade cavity resonance problem caused by W-band power divider. The power divider uses traditional T-junction Wilkinson structure. A novel method by setting the appropriate cut-off frequency, either complete the W-band power distribution, but also isolate the low harmonics (60GHz in this design) at the same time. A very broad bandwidth from 80GHz up to 100GHz is obtained. In the meanwhile, output return loss is better than -15dB by EM simulation.
