The design of the low loss filter for the UWB wireless signal of ship's multiuser under the wind and waves is of great significance to the development of the ship communication in China. At present, the design of the filter in this aspect is completed according to the design principle of EML, and there is a problem of big difference between the test value and the actual value. The traditional UWB filter which has optimizes the structure of high pass short-ended stubs is as the design basis, in the half wavelength transmission line connecting short-ended stubs line, the resonator structure units of dual-mode and tri-mode stubs are loaded to achieve the performance of dual-trapping or tri-trapping waves. The miniaturized UWB filter based on the folding short-ended stubs is designed; and the folding form of dual-mode and tri-mode resonators are applied to UWB filter design, to implement the UWB filter dual-trapping or tri-trapping waves. The experiment shows that the experimental value of the proposed method is consistent with the actual value, and have good reliability.
