Abstract

A narrowband low temperature co-fired ceramic (LTCC) bandpass filter (BPF) with five cascaded physical length-reduced resonators is proposed. Each resonator is built with cascaded horizontal and vertical microstrip lines to produce slow-wave effect, which reduces the physical length of resonators for miniaturization. The entire size of the proposed BPF is only 15 x 2 x 0.3 mm, and a size reduction of 60% is achieved compared with a traditional implementation. A narrowband fractional bandwidth (FBW) of 4% and an average passband insertion loss of only 2.4 dB are achieved. Comparison and discussion are implemented as well.
