摘要： An antenna device includes a loop-shaped element radiating a radio wave of at least wavelength λ and having an electrical length of m×λ; a first power feeder exciting the loop-shaped element via voltage or current coupling by using a first electrical signal for radiating the radio wave; and a second power feeder exciting the loop-shaped element via a coupling method that is the same type as the first power feeder by using a second electrical signal for radiating a radio wave of wavelength λ/(2×p−1) at a portion that becomes a node of a standing wave that is formed with the first power feeder as an anti-node and that is based on the first electrical signal, here, “m” and “p” are natural numbers.

摘要： An antenna element is formed by providing a radiation electrode on a base member made of a dielectric material. To protect the antenna element from external impact, a void is formed between a housing and the antenna element. This void is filled with a solid member. The relative permittivity of the solid member is equal to or higher than the relative permittivity of the housing, and equal to or lower than the relative permittivity of the base member. The solid member is formed as an elastic member.
摘要翻译：通过在由电介质材料制成的基底构件上设置辐射电极形成天线元件。为了保护天线元件免受外部冲击，在壳体和天线元件之间形成空隙。该空隙填充有固体成分。实心构件的相对介电常数等于或大于壳体的相对介电常数，等于或低于基体的相对介电常数。实心构件形成为弹性构件。
