Abstract
An apparatus, including an antenna array of antenna elements having signal feeds configured to convey a pair of radio frequency signals related to a pair of polarised beams; and circuitry coupled to the signal feeds and configured to vary a gain of the pair of radio frequency signals conveyed between the signal feeds and front end circuitry to vary an orientation of the pair of polarised beams.

An apparatus, comprising:
- an antenna array of antenna elements having signal feeds configured to convey a pair of radio frequency signals related to a pair of polarised beams, wherein said pair of radio frequency signals comprise a first radio frequency signal related to a first beam polarised in a first orientation and a second radio frequency signal related to a second beam polarised in a second orientation;
- and
- circuitry coupled to the signal feeds and configured to vary a relative gain of said pair of radio frequency signals conveyed between said signal feeds and front end circuitry to vary a polarization orientation of said pair of polarised beams.
