    • A small and inexpensive planar dielectric line that can be easily connected to electronic parts, such as ICs, and has smaller conduction losses. The planar dielectric line includes a dielectric substrate having first and second surfaces opposedly facing each other. A first slot having a predetermined width is interposed between first and second electrodes on the first surface of the dielectric substrate. A second slot having the same width as the first slot is disposed between third and fourth electrodes on the second surface of the dielectric substrate. The first and second slots opposedly face each other. The permittivity and the thickness of the dielectric substrate are determined so that a planar electromagnetic wave can propagate in a propagation region of the substrate interposed between the first and second slots while being substantially totally reflected on the first surface of the substrate adjacent to the first slot and the second surface of the substrate near the second slot. When the permittivity and the thickness of the dielectric substrate are determined to meet the following conditions, 80% or more of the total electric field energy is confined within a region which is small enough to substantially eliminate interference with an adjacent line:(relative permittivity of dielectric substrate).gtoreq.10 (thickness "t" of dielectric substrate).gtoreq.0.3 mm. When the relative permittivity is at least 18, 90% or more of the total electric field energy is confined.
    • 可以容易地连接到诸如IC的电子部件的小且廉价的平面介质线,并且具有较小的传导损耗。 平面介质线包括具有彼此面对的第一和第二表面的电介质基板。 具有预定宽度的第一槽介于介质基板的第一表面上的第一和第二电极之间。 具有与第一槽相同宽度的第二槽设置在电介质基板的第二表面上的第三和第四电极之间。 第一和第二槽相对地面对。 确定电介质基板的介电常数和厚度,使得平面电磁波可以在介于第一和第二槽之间的基板的传播区域中传播,同时基本上完全反射在与第一槽相邻的基板的第一表面上 以及在第二槽附近的衬底的第二表面。 当介电基片的介电常数和厚度确定为满足以下条件时,总电场能量的80%以上被限制在足够小的区域,以便基本上消除与相邻线的干涉:(相对介电常数 介电基片)> = 10(介电基片的厚度“t”)= 0.3mm。 当相对介电常数至少为18时,限制了总电场能量的90%以上。
