Abstract(in Japanese) (See Japanese page)
Abstract(in English) A lossy resonator filter was proposed for suppressing noise propagation in the power-ground plane pair of a printed circuit board (PCB) at high frequencies over 1 GHz. The lossy resonator filter has an advantage of frequency selectivity because the frequency band to suppress noise propagation is specified by changing the resonant frequency of the resonator included. Also, the suppressed noise does not regenerate owing to a loss given to the resonator. In this paper, the lossy resonator filter was fabricated by covering the open stubs with a ferrite thin film on a PCB. Then, its characteristics were verified by evaluating the transmission coefficient through full-wave simulation and measurement using a vector network analyzer. The measurement and simulation results show that the noise in the power bus of the PCB at frequencies over 1 GHz is suppressed. Even in the case that the power bus is inside the board, noise propagation in the power bus was suppressed by connecting the inside ground plane and the ground plane of the lossy resonator filter by vias in order to conduct the noise to the filter.
