The paper is devoted to an investigation of two-conductor suspended-substrate resonators.
For the purpose of miniaturization conductors of a resonator are folded. Four types of the resonator
differing in conductors’ configurations were considered. Their Q0-factors and resonant frequencies were
studied. Based on results of the study two types of the resonator appeared unsuitable for an application
in compact filters. Two other types were investigated in concern of their interaction: dependencies of
coupling coefficients versus space between resonators and versus distance from substrate’s surfaces, and
package’s covers were obtained. Based on the dependences a type of the resonator suitable for designing
compact BPF was chosen. A four-pole BPF was simulated and fabricated. Good agreement between
simulated and experimental results is observed. The main filter’s characteristics are the next: substrate
has ε = 80, thickness 0.5mm, lateral sizes 0.13λg ×0.09λg (18.7mm×13.2 mm). The central frequency
is 305 MHz; bandwidth is 39 MHz; passband minimum insertion loss is 2.0 dB; passband return loss is
less −14.6dB; −40 dB stopband width is 480MHz
