The first substrate integrated waveguide dual-band bandpass filter with wide-stopband performance is presented. This filter is synthesised and designed with fourth-order Chebyshev responses and identical fractional bandwidths for the two passbands centred at 12 and 16 GHz. Multiple spurious resonances have been intrinsically suppressed by introducing the harmonics-staggered technique and the centred...
Compact open-loop resonators loaded by open stubs are used to design cross-coupled filters with a dual-passband response of Chebyshev function. The second passband of the proposed filter is obtained by tuning higher resonant modes of the open-loop resonator by changing the stub length and position. Proper couplings required for the two desired/designed frequencies are obtained by tuning the relative...
In this paper, a new synthesis technique using successive circuit conversions is proposed. By inserting ideal admittance inverters and ideal transformers, the conventional asymmetrical even-order Chebyshev filter can be converted to new symmetrical filter topology; also, the source and load resistances are equal. For bandpass filter (BPF), admittance inverters can be easily realized with series lambdag/4...
