Abstract: A tri band, Multi layer circularly Polarized (CP) slot antenna backed with dual frequency Selective surface with incremental feed-line is designed and fabricated. The design consists of two crescent shaped slots with incremental feed line and two reflectors. The half moon shaped structure employs circular polarization with beam tiled problem can be overcome by dual slot structure backed with FSS, a high gain is obtained. The measured results offer an 11.84 %( 4.21 GHz–4.74 GHz), 11.83 %( 5.9-6.7 GHz), 5.9 %( 7.9-8.4 GHz) CP bandwidth. By introducing the dual FSS reflector, 11.1 dBi of peak gain is also obtained at 6 GHz which is greatly enhanced when compared with the antenna without FSS. A high gain is obtained with simple structure for CP bandwidth is simulated and measured.
Keywords: Frequency Selective Surface (FSS), Crescent Shapes, Circularly Polarized (CP).
