ABSTRACT:
The present invention relates to a dual-feed antenna. The invention provides an antenna comprising first and second electromagnetic radiation paths which join to form a common third electromagnetic radiation path, wherein the first path is rotatable with respect to the second path. In this way, two antenna feeds can be directed independently of one another, whilst combining the electromagnetic radiation paths from the antenna feeds then allows a common set of components to be used in signal analysis or generation.
