Abstract :
In this paper, A W-band substrate integrated waveguide (SIW) filter is presented by using printed-circuit-board technology. The aggressive space mapping (ASM) optimization algorithm is adopted for designing the SIW bandpass filter. Fin line structure is proposed as the transition structure form SIW to waveguide. As demonstrations, A W-band SIW filter is fabricated on substrate RO5880 and measured by using VNA. Good agreements between simulated and measured results were obtained.
