A novel microstrip filter based on transverse electromagnetic (TEM)‐substrate integrated waveguide (SIW) cavities is firstly proposed in this letter. Compared to the traditional SIW cavities, the TEM‐SIW cavities have more compact size and higher Q value. Then, two bandpass filter adopting TEM‐SIW cavities is designed and one of it is fabricated. Both simulated and measured results are presented. © 2012 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2012.
