Abstract :
A dual-screen DSL (double-square-loop) FSS (frequency-selective surface) is designed to multiplex the S, X, Ku and Ka frequency bands for the NASA CRAF/CASSINI mission. Specifically. this four-frequency FSS reflects the X (7.2/8.4-GHz) and the Ka (32/34-GHz) waves but transmits the S-band (2.3-GHz) and the Ku-band (13.8-GHz) waves. The dual-screen DSL FSS may be operated for both transverse electric and transverse magnetic (or circular) polarizations and for incident angles steered from normal to 45 degrees . This FSS was fabricated using the conventional PWB technique.<>
