Antenna arrangement and a method in particular for its operation

Antenna arrangement comprising:

• at least two antenna element systems each being at least one antenna element arranged offset with respect to one another, at least in the horizontal direction,
• the at least two antenna element systems transmitting and receiving at least in one common polarization plane,
• a network, via which the at least two antenna element systems can be supplied with a signal with an intensity or amplitude which can be adjusted relative to one another further including:
• the at least one network being arranged such that a different beam shape is used for receiving signals as compared to transmitting signals.

Method for operating an antenna arrangement comprising:

• varying an input signal via a phase adjusting device or a phase shifter adjusting device and a downstream network such that the signal at the output of the network and thus at the at least two inputs is in phase or is not in phase, preferably with a 180° phase shift, to provide a horizontal radiation pattern corresponding to a horizontal polar diagram, which is at least one of:
• (a) asymmetric,
• (b) symmetrical and has at least two main lobes which are symmetrical with respect to a vertical plane at right angles to the reflector plane, and/or
• (c) has at least three main lobes or an odd number of main lobes, whose maximum intensities differ from one another by less than 50%.
