ABSTRACT:
The disclosed antenna system includes a non-conductive parabolic dish, a first antenna array rigidly positioned in front of the dish, and a second antenna array extending through the dish and having radiating elements on either side thereof. In one embodiment, a plurality of conductive strips are disposed on the dish in a polarization selective pattern; the first antenna array generates linearly polarized electric fields that are reflected by the strips; and the second antenna array generates linearly polarized electric fields that pass through the strips. In another embodiment of the invention a plurality of conductive areas are disposed on the dish in a checkerboard frequency selective pattern; the first antenna array generates electric fields in a frequency band that are reflected by the pattern; and the second antenna array generates electric fields in a frequency band that are passed by the pattern.
