Abstract

An antenna arrangement (200, 300, 400) with antenna units (220, 230) comprising an input port (201, 202); a power divider (202, 204) for dividing an input signal into a major and a minor part with a ratio 1:1; a network (211, 216) with a sum input port; a difference input port, and first and second output ports; first (215, 217) and second antenna (214, 218) 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.
