    Abstract: A transmission line includes, in a dielectric body, a first ground conductor, and first and second signal conductors arranged in a width direction of the dielectric body. The first ground conductor includes a first signal conductor ground portion disposed closer to a first side of the dielectric body in a thickness direction than the first signal conductor, a second signal conductor ground portion disposed closer to a second side of the dielectric body in the thickness direction than the second signal conductor, and an intermediate portion that connects the first signal conductor ground portion to the second signal conductor ground portion. The intermediate portion is disposed between a first transmission line including the first signal conductor and the first signal conductor ground portion and a second transmission line including the second signal conductor and the second signal conductor ground portion.

    Abstract: A communication terminal in which a card antenna module is loaded into a terminal casing including an antenna is operated such that a degree of coupling between a terminal-casing-side antenna and a module-side antenna is minimized and that a module-side antenna has a desired frequency characteristic. The communication terminal includes a terminal casing including a terminal-casing-side antenna, and a card antenna module loaded into the terminal casing. The card antenna module includes a coupling coil which is disposed at a position close to the terminal-casing-side antenna and which is coupled with the terminal-casing-side antenna via a magnetic field, and a module-side antenna which is disposed at a position more distant from the terminal-casing-side antenna than the coupling coil.

    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: A main transmission line includes a substantially elongated dielectric body in which first and second substantially elongated signal conductors are disposed with a distance therebetween in a width direction. A first reference ground conductor and a first auxiliary ground conductor sandwich therebetween the first signal conductor in a thickness direction. A second reference ground conductor and a second auxiliary ground conductor sandwich therebetween the second signal conductor in the thickness direction. The second auxiliary ground conductor includes two substantially elongated conductors and a first bridge conductor, and the second auxiliary ground conductor includes two substantially elongated conductors and a second bridge conductor. The positions of the first and second bridge conductors in a lengthwise direction are different.
