    • An antenna, in particular a mobile radio antenna, operates in at least two frequency bands. Two or more dipole antenna elements are provided and are arranged in front of a reflector, which transmit and receive in two different frequency bands. The distance between the antenna element structure, the antenna elements or the antenna element top of at least one dipole antenna element for the higher frequency band is at a distance from the reflector plane which corresponds to at least 75% and at most 150% of the distance between an antenna element structure. An antenna element or an antenna element top of at least one dipole antenna element for the lower frequency band and the reflector plane, and/or the distance between the antenna element structure, the antenna elements or the antenna element top of at least one dipole antenna element for the higher frequency band is at a distance from the reflector plane which is greater than 0.4λ and is preferably less than 2λ with respect to the mid-frequency of the antenna element for the higher frequency.
    • 天线,特别是移动无线电天线,在至少两个频带中工作。 提供了两个或更多个偶极天线元件,并且被布置在反射器的前面,反射器在两个不同的频带中发送和接收。 用于较高频带的至少一个偶极天线元件的天线元件结构,天线元件或天线元件顶部之间的距离与反射器平面成一定距离,对应于至少75%且至多150% 天线元件结构之间的距离。 用于较低频带和反射器平面的至少一个偶极天线元件的天线元件或天线元件顶部,和/或至少一个偶极子天线的天线元件结构,天线元件或天线元件顶部之间的距离 较高频带的元件距反射器平面的距离大于0.4λ,相对于较高频率的天线元件的中频优选小于2λ。
