Abstract

An antenna arrangement (10) of the kind, which includes a reflector (11), preferably provided on supporting means (12, 13, 14, 15), a central unit (22) comprising means (31) for guiding collected electromagnetic waves by said reflector (11) and guiding said waves to receiving means (34, 35). Said antenna (10) further includes: at least one dielectric element (29), having property to vary the rotation of said electromagnetic waves, and/or means to radially displace said receiving means (34, 35) relative said wave guiding means (31), and/or a sleeve (40), a socket (42) arranged rotatably in relation to said sleeve (40) and a dielectric element (44) provided inside said socket (42). The invention also includes methods of improving conical scanning, polarisation rotation and circular/linear commutation polarisation in said antenna.
