This session features a variety of innovative planar filters using substrate integrated waveguide (SIW) and microstrip technologies. The first paper presents a compact, quasi-absorptive SIW filter using capacitively-loaded resonators. The second paper describes a compact, dual-mode SIW filter using uniform impedance resonators. Third, a compact bandpass filter using substrate integrated defected ground structure (SIDGS) is described that achieves a very wide stopband response. Next, stepped impedance resonators (SIR) and complementary split ring resonators (CSRR) are combined to create filters with high selectivity. The last paper presents a balanced bandpass filter using coupled lines to produce a quasi-elliptic bandpass and ultra-wide stopband response.
