It is shown that our proposed compact filter operates below the cutoff frequency of conventional SIWs. No spurious responses, corresponding to the higher-order resonant modes of the resonator, appear within an octave band of the central frequency. Its attractive performance is validated numerically ...
3-dB fractional bandwidth (FBW).FBW can be varied between 10%and 100%.In addition,filters have the advantages of compactness,sharp rejection,low insertion loss (IL),and low cost.Two prototype fabricated filters of FBW 10.8%and 81.6%show a maximum passband IL of 1.2dB.Filter occu-...

In this paper, a new technique using two p-i-n diodes to switch between two channels of a tunable diplexer with constant return loss is proposed to design a tunable bandpass filter (BPF) with wide frequency tuning range (FTR). The used third-order tunable diplexer with two independently tun...
