Abstract
An antenna system () comprising a single antenna element having first () and second () antenna ports arranged to pass a respective first and second antenna signal. The first and second antenna signals being derived from a first common antenna signal (J) and arranged to be essentially equal in envelope. An antenna pattern of the system being arranged to be selectable between a first antenna pattern having a first polarization and a second antenna pattern having a second polarization substantially orthogonal to the first polarization. The first antenna pattern being selected by setting the first and second antenna signal to have the same polarity on first () and second () antenna ports, the second antenna pattern being selected by setting the first and second antenna signal to have substantially opposite polarities on first () and second () antenna ports.
