A Ka-Band FSIW Band-Pass Filter with LTCC Technology
This paper presents a Ka-band miniaturized bandpass filter with folded substrate integrated waveguide (FSIW) resonators in multilayer low-temperature cofired ceramic (LTCC) technology. The FSIW resonator is formed by inserting a metal plate with two orthogonal slots into the cavity, which is used for the circuit size reduction with its footprint about a quarter of the conventional TE101 mode and also has the merits of high Q and low-loss. The vertically stacked cavities are coupled by Circle-shaped slots. Based on this structure and LTCC technology, a two-order cross-coupling FSIW cavity filter is proposed. The filter has compact size and realizes two transmission zeros at both low and high rejection bands. The simulation results: insertion loss and return loss better than 0.3 dB and 20dB, respectively, in the pass-band of 30.1-31.2GHz.
