SIGNAL DISTRIBUTION NETWORK

Abstract:

A signal distribution network associated with first and second antenna ports and first and second pluralities of antenna elements is disclosed, which is configured to cause feeding of a first signal to/from the first and second pluralities of antenna elements via distribution nodes and using a first ordered weighting set, and feeding of a second signal to/from the first and second pluralities of antenna elements via distribution nodes and using a second ordered weighting set. The first ordered weighting set comprises a first weighting element for each distribution node, each non-zero valued first weighting element being configured to provide a first signal contribution factor for first and second polarizations when combined with the antenna element orientation. The second ordered weighting set comprises a second weighting element for each distribution node, each non-zero valued second weighting element being configured to provide a second signal contribution factor for first and second polarizations when combined with the antenna element orientation.
