内容記述(抄録等)Low leakage-loss of Conductor-Backed Coplanar Waveguide (CBCPW) with air-gap-spacing (AGS) dielectric sheets has been already proposed numerically by using the hybrid 2D-FDTD analysis and the curve-fitting procedure. From the numerical results, the low leakage-loss characteristics and the existence of the optimum width for the air-gap have been confirmed. In this paper, we have mainly discussed on the relationship between the leakage-loss and the location of the air-gap. To explain this relationship, we have analyzed the characteristics for asymmetrically located air-gap structure. As the first step, the air-gap width is expanding toward the right-way with keeping the position of another side edge, as the next step, the location of the air-gap is moved toward the right-way with keeping the air-gap width. From these analytical results, we have also tried to find out what is dominantly affected on the leakage-loss reduction of CBCPW with AGS dielectric sheets.
