The design study of new button-type beam position monitor (BPM) is performed for a high accuracy bunch-by-bunch BPM system. Particularly it is mainly to compensate the influence of ringing signal which causes the misreading of the beam position of following bunches. The ringing is produced by the combined effect of an impedance mismatching inside the button and trapped TE-mode inside the aluminum-oxide insulator material. In this presentation, we will present design considerations and calculation results.
