    • An antenna, especially for use with mobile radios, that is mounted in an opening of a motor vehicle. The antenna includes at least one radiator with connecting line and the radiator is mounted in the opening behind a nontransparent, nonconductive covering. In one embodiment the radiator is configured as a monopole with matched balancing antennae that are strip conductors laid out on a printed circuit board attached to a ventilation structure mounted in an opening behind a covering nonconductive bumper.
    • 特别是用于移动无线电的天线,其安装在机动车辆的开口中。 天线包括具有连接线的至少一个辐射器,并且散热器安装在不透明,不导电覆盖物后面的开口中。 在一个实施例中,散热器被配置为具有匹配的平衡天线的单极子,其是布置在安装在覆盖非导电保险杠后面的开口中的通风结构的印刷电路板上的带状导体。

    • In an antenna having at least one vertical radiator, preferably a vehicle mobile radiotelephone antenna, the at least one vertical radiator is connected to the ground on one end and to a vertical conductor fed against the ground on the other end by means of an impedance transforming device having an electrical length which is approximately one fourth the mean operating wavelength or an uneven multiple thereof. Said structure makes it possible for the at least one vertical radiator to have a uniform current occupancy over its entire length. By cooperating with the vertical conductor fed in a co-radiating manner, said occupancy exhibits high radiation power comparable to that of a &lgr;/4 monopole antenna despite the fact that the at least one vertical radiator has a smaller length which is approximately {fraction (1/10)} of the mean operating wavelength. The invention also describes advantageous embodiments or configurations of said antenna and practical arrangements of said antenna in vehicles.
    • 在具有至少一个垂直辐射器的天线中,优选地是车辆移动无线电话天线,所述至少一个垂直辐射器在一端连接到地面,并且通过阻抗变换连接到另一端向地面馈送的垂直导体 器件,其电长度约为平均工作波长的四分之一或其不均匀倍数。 所述结构使得至少一个垂直辐射器在其整个长度上具有均匀的电流占有率成为可能。 通过与以共同辐射方式馈送的垂直导体协作,所述占用率表现出与羔羊/ 4单极天线相当的高辐射功率,尽管事实上至少一个垂直辐射器具有较小的长度,其大约为{分数( 平均工作波长的1/10。本发明还描述了所述天线的有利实施例或配置以及所述天线在车辆中的实际布置。
