Abstract

In this paper, a miniaturized substrate integrated waveguide (SIW) band-pass cavity filter is presented. Miniaturization is achieved using the half-mode (HM) principle so the lateral dimension of the filter can be reduced by half. Moreover, the slow-wave (SW) technique is used to decrease the center frequency by more than \(30\%\). Combining these two techniques will reduce filter dimensions by more than \(75\%\) in comparison with the original SIW. By using an electromagnetic (EM) solver the effect of each geometrical parameter on the filter performance is demonstrated. Measurements on the fabricated filter are in good agreement with the numerical results. Input return loss is better than 10 dB, insertion loss of the filter is lower than 2.5 dB across a bandwidth of 3.3 GHz.
