Abstract This research involves a compact wideband circularly-polarized antenna array, which consists of a sequential rotating phase feed network, 2 × 2 mushroom-type metamaterial (MTM) unit, and so on. Each antenna array unit contains a microstrip feedline, an L-shaped slot antenna, and so on. The MTM-based antennas were incorporated with a sequential-phase network of sequentially rotated series-parallel feed to achieve wideband operation. The operational bandwidth and the radiation model in the high-frequency area were improved through the adjustment of spacing between the L-shaped slots while maintaining the size and structure of the MTM. The proposed design had dimensions of 80 mm × 80 mm × 3.5 mm (~1.64 λ0 × 1.64 λ0 × 0.072 λ0 at 6.15 GHz), and it was simulated, fabricated, and tested.

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.
