Design of dichroic compact reflectors systems
A compact system is designed to radiate in 2 different frequencies and directions. Selective frequency behavior is achieved by replacing the reflectors by FSS. The upper reflector reflects at 5 GHz, but it is transparent at 8 GHz, and the lower reflector reflects at 8 GHz, but it is also has a frequency selective behavior
Design of dichroic cassegrain reflector at C&X or Ku&X frequency bands
A Cassegrain reflector is analyzed at C, X and K bands. Selective behavior is achieved by replacing the reflectors by FSS crosses. FSS-subreflector may reflect at C and Ku bands, but it is transparent at X band. Main reflector is feed at X band.
