摘要： PROBLEM TO BE SOLVED: To improve the radiation efficiency of folded antenna equipment having a meander, helical, or spiral shape.
SOLUTION: A plate-like conductor is arranged between a first conductor 10 and a second conductor 12 to cause electrical field coupling between the first conductor 10 and the plate-like conductor 13 and also between the plate-like conductor 13 and the second conductor 12. Consequently, a current in a direction opposite from that of a current in the first conductor 10 is caused to flow in the plate-like conductor 13 and a current in a direction opposite from that of the current in the plate-like conductor 13 is caused to flow in the second conductor 12. In other words, the current in the first conductor 10 and the current in the second conductor 12 are directed in the same direction and a symmetrical mode becomes dominant. As a result, an input resistance Rf of the antenna equipment 7 can be close to four times, easily establishing matching between the antenna equipment 7 and a wireless circuit connected to a power feeding portion 9.

摘要翻译：要解决的问题：提高具有曲折，螺旋形或螺旋状的折叠天线设备的辐射效率。解决方案：板状导体布置在第一导体10和第二导体12之间，以在第一导体10和板状导体13之间以及板状导体13与第二导体13之间形成电场耦合。因此，使与第一导体10中的电流相反的方向的电流在板状导体13中流动，并且在与板状导体13中的电流相反的方向上流动电流导体13在第二导体12中流动。换句话说，第一导体10中的电流和第二导体12中的电流指向相同的方向，并且对称模式成为主导的。结果，天线设备7的输入电阻Rf可以接近四倍，容易建立天线设备7与连接到馈电部分9的无线电路之间的匹配。（C）2008年， JPO＆INPIT

SOLUTION: An antenna device 16 includes: a grounding subject 17; a feeder 18 insulated from the grounding subject 17; a first conductor 20 shaping like substantially a looped triangle and coupled to the feeder 18 at a first feeder top 19; and a second conductor 22 line-symmetric to the first conductor 20 with a line passing through the feeder 18 as a symmetry axis and coupled to the feeder 18 at a second feeder top 21. The first feeder top 19 is placed closest to the grounding subject 17 among other elements of the first conductor 20, and the second feeder top 21 is placed closest to the grounding subject 17 among other elements of the second conductor 22. The foregoing structure allows a high electrical field section of a first side 23 of the first conductor and that of a first side 26 of the second conductor to leave further away from the grounding subject.
