Abstract
In a dual-band antenna of the beam wave-guide type, first and second electromagnetic waves from first and second feed horns, respectively, are directly provided to a frequency selective reflector along different axes, with both electromagnetic waves being provided from the frequency selective reflector along the same axis. The two electromagnetic waves are then reflected in common by first and second concave mirrors and then provided substantially along an axis coincident with the azimuth axis to the remainder of the beam wave-guide section which is itself rotatable about the azimuth axis.
