Abstract:
A metasurface based on unequal spacing between the rectangular-ring unit cells is used to propose a broadband, low profile, circularly polarized (CP) and linearly polarized (LP) antenna. This can be used for 5G New Radio and GNSS applications in navigation and telemetry on drone which uses remote sensing radar/lidar for survey mapping. The antenna structure comprises a stacked-metasurface based on unequal-spacing between the 7×7-unit cells, a radiating rectangular-patch, and a near diagonal line probe feed. A metasurface is considered using rectangular-ring 7×7-unit cells array with unequal-spacing’s in x- and y-directions and it is placed above a rectangular-radiator to realize a wide CP bandwidth for GNSS applications. The antenna example reaches a 3dB axial ratio of 25.3% (1.38 GHz – 1.78 GHz) with CP (3-dB axial ratio) bandwidth of 15.8% (1.51 GHz – 1.77 GHz) and gain of greater than 8.5 dBic.
