A compact wideband bandpass filter with a pentagonal-shaped open-loop folded step-impedance-resonator (SIR) using low temperature co-fired ceramic (LTCC) technology has been designed and fabricated. The filter is composed of three pentagonal-shaped open-loop SIRs embedded in multilayer thin ceramic to produce a compact size. The proposed topology is demonstrated with a design operating at 4.3 GHz with 44.2% bandwidth. More than 20 dB of spurious suppression from 6 to 11 GHz is demonstrated in the experimental results.
