Abstract :
This paper presents the development of a frequency selective surface prototype. Both single screen and double screen mock-ups are generated for a two bands system that reflects X-band (8.025 to 8.4 GHz) signals and transmits S-band (2.2 to 2.3 GHz) signals. Circular ring has been chosen for the element shape due to its insensitivity to a large variation of the RF incident angle. The analysis and design of a single screen dichroic subreflector have been carried out.
