MULTIBAND GRIDDED FOCAL PLANE ARRAY ANTENNA

摘要

A multiband gridded focal plane array antenna 10 is disclosed which provides simultaneous beams of multiple frequencies. The antenna 10 includes a metallization pattern 11 providing a first set of conductive edges 18 having a first length L and a second set of conductive edges 20 having a second length L2. The first and second sets of conductive edges are separately fed to provide the first and second simultaneous output beams at first and second operating frequencies.
