Abstract
An arrangement for providing communication between a radio antenna and a radio base station in a cellular communication system. A waveguide is configured to connect the radio base station to the antenna. The waveguide may be connected directly or indirectly to the radio base station and/or the antenna. The waveguide is configured with a number of compartments, each compartment acting as a waveguide for a particular signal. The arrangement is thus able to convey a large number of signals, for example, for sector antennas of dual polarization type and for more than one frequency band.
