| Abstract: | In order to meet the characterization of circuit miniaturization, the design method was proposed on via subject structure loaded with open and short stub resonator object structure, of which the new band-pass filter is now available. After the simulation and optimization, the physical processing test was carried out, and the volume size of the filter is 40 mm ×20 mm×0.9 mm, and the operating frequency can reach the range of 1.36 ~2.83 GHz, relative bandwidth is 70.2%, the insertion loss in band is less than 1.5dB, the return loss is better than -15dB, the maximum suppression outside the band is better than -40dB. The measured values are in good agreement with the simulated values. |
