A NODE AND A METHOD IN A WIRELESS COMMUNICATION SYSTEM, HAVING DIFFERENT ANTENNA FUNCTIONAL MODES

摘要

The present invention relates to a node in a wireless communication system, which comprises at least one transceiver unit, a first and a second antenna function. The antenna functions comprise a first and a second port connection. The transceiver unit is arranged to communicate by means of at least one frequency band. Each port connection is connectable to said transceiver unit via electrical signal delays of different magnitudes. In a first mode of operation, a certain resulting main radiation lobe is acquired when the antenna functions are receiving or transmitting for each frequency in the frequency band. Said main radiation lobe has a main pointing direction with a certain angular direction in azimuth and elevation with respect to a fixed angular direction. The angular direction for every certain frequency is different from the angular direction for any other frequency.
