Abstract
An antenna arrangement () with antenna units () comprising an input port (), a power divider () for dividing an input signal into a major and a minor part with a ratio 11, a network () with a sum input port, a difference input port, and first and second output ports, first () and second antenna () elements of a first and a second polarization. Signals to the sum input port are output with a first relation between them and signals to the difference input port are output with a second phase relation. The antenna units are arranged so that the major part of an input signal is connected to the sum port of a network and the minor part of an input signal is connected to the difference port of another network, and the first and second output ports of a network are connected to first and second adjacent antenna elements of the same polarization.
