The tapered-coupler stripline beam position monitor has been used for the intra-bunch feedback system in the J-PARC MR. It should be realized with a special shaped striplines, for example, whose width is tailored exponentially and whose gap distances between the inner surface of the beam pipe should be also decreasing as a exponential function in order to keep the characteristic impedance 50 ohm. This 3D varying geometry makes it difficult to achieve the good balance between the electrode responses to the beam. We present a new design method with a groove, which may give simpler geometry and flatter frequency response.
