Abstract: In one embodiment, a multi-beam antenna is described. The multi-beam antenna includes a reflector having a single reflector surface defining a first focal region and a second focal region. A first feed group is located within the first focal region. The first feed group includes a first feed oriented relative to the reflector define a first beam pointed in a first direction. The multi-beam antenna further includes a fixed attachment mechanism attaching the first feed group to the reflector such that a position of the first feed group is fixed relative to the reflector. The multi-beam antenna further includes a second feed group located within the second focal region. The second feed group includes a second feed oriented relative to the reflector to define a second beam pointed in a second direction. The multi-beam antenna further includes an adjustable attachment mechanism attaching the second feed group to the reflector in an adjustable relation to the reflector, whereby a difference between the first direction and the second direction is adjustable.

Abstract: In an example embodiment, a waveguide device comprises: a first common waveguide; a polarizer section, the polarizer section including a conductive septum dividing the first common waveguide into a first divided waveguide portion and a second waveguide divided portion; a second waveguide coupled to the first divided waveguide portion of the polarizer section; a third waveguide coupled to the second divided waveguide portion of the polarizer section; and a dielectric insert. The dielectric insert includes a first dielectric portion partially filling the polarizer section. The conductive septum and the dielectric portion convert a signal between a polarized state in the first common waveguide and a first polarization component in the second waveguide and a second polarization component in the third waveguide.
