Abstract :
In this paper, a substrate integrated waveguide (SIW) filter with two transmission zeros is proposed. By using source-load coupling, two finite transmission zeros are obtained. A second order SIW filter with the center frequency of 15 GHz was simulated, fabricated and measured, whose bandwidth is 160 MHz. The measured results agree well with the simulated results.
