An improved radio-frequency phase shift assembly includes at least one further stripline section arranged concentrically with respect to a first stripline section. Further connection lines are provided, via which an electrical connection is produced at least indirectly from the feed line to the respective tapping section associated with a stripline section. Two different pairs of antenna radiating elements can be driven with different phase angles (Φ) at mutually offset tapping points on the at least two stripline sections. The plurality of connection lines are mechanically connected to one another.

An antenna feed network is provided with a capacitive coupling device via which a capacitive connection exists to a coupled line. The coupled line section is firmly connected to the downstream appliance or antenna element, or is part of the appliance or antenna element, in the region of the capacitive coupling device. The feed network has a first coupling section and the coupled line has a second coupling section. The two coupling sections are fixed with respect to one another by means of a bracket and/or holding device in a relative position such that relative movement between the two coupling surfaces can take place parallel to the coupling surface.

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.
