Abstract
In this paper, an ultra-wideband circular polarization (CP) maintaining reflector is proposed based on an anisotropic metasurface, which is an orthogonal anisotropic structure with a pair of symmetrical axes u and v perpendicular to each other. The simulated results show that the reflector can realized CP-maintaining reflection under both right-handed and left-handed CP (RHCP and LHCP) incidences in the frequency band between 8.79 and 27.09 GHz, the fractional bandwidth is up to 102%. In addition, the physical mechanism of the CP-maintaining reflection has been analyzed in detail, and one useful formula has been derived, which can be used to calculate the cross- and co-polarization reflection coefficients under CP incidence according to the phase differences between the two reflection coefficients under u and v-polarized incidences. Finally, one effective experimental validation was carried out.
