    Abstract: A first signal line is closer to a second ground conductor than a second signal line and, hence, crosstalk between the first and second signal lines is unlikely to be generated. By providing first opening portions in the second ground conductor, capacitive coupling between the first and second signal lines is reduced. Hence, in a transmission line including the first signal line, an increase in the capacitance due to the increased width of the first signal line is cancelled out by a decrease in the capacitance due to the increased distance from the first ground conductor and the first opening portions. Further, the width of the high-frequency transmission line need not be large. Further, since the capacitance is reduced by the first and second opening portions, the distances between the first ground conductor and the first and second signal lines are shortened.

    Abstract translation: 第一信号线比第二信号线更靠近第二接地导体，因此不可能产生第一和第二信号线之间的串扰。 通过在第二接地导体中设置第一开口部分，减小了第一和第二信号线之间的电容耦合。 因此，在包括第一信号线的传输线中，由于与第一接地导体和第一开口的距离增加，由于第一信号线的宽度增加而导致的电容增加被抵消了电容的减小 部分。 此外，高频传输线的宽度不必大。 此外，由于通过第一和第二开口部分减小电容，所以第一接地导体与第一和第二信号线之间的距离缩短。

    Abstract: An LC parallel resonant element includes a first planar or substantially planar conductor on a first base material layer and second and third planar or substantially planar conductors on second and third base material layers. The first and third planar or substantially planar conductors extend over nearly the entire surfaces of the first and third base material layers. The second planar or substantially planar conductor extends over nearly the entire length of the second base material layer in a second direction such that a space from the other end portion of two end portions of a multilayer body in a first direction is provided. The first and third planar or substantially planar conductors are connected to each other by interlayer conductors near the other end portion of the multilayer body. The first and second planar or substantially planar conductor are connected to each other by interlayer conductors near one end portion of the multilayer body.

    Abstract: In an antenna device, first linear portions of a coil conductor are located on a lower surface of a first resin sheet. Second linear portions of the coil conductor are located on an upper surface of a second resin sheet. Via conductors of the coil conductor are formed in the first and second resin sheets and intermediate resin sheets located between the first and second resin sheets. The via conductors connect a first end and a second end of the first linear portions and a first end and a second end of the second linear portions, respectively. The first and second linear portions and the via conductors define the coil conductor. Each of the intermediate resin sheets includes an aperture in the center portion thereof. The lamination of the apertures defines a cavity in which a magnetic substance core is embedded. The coil conductor is wound around a periphery of the cavity.
