Abstract

A new circularly-polarized metasurfaced dipole antenna (MSDA) with wide axial-ratio(AR) beamwidth and radar cross section (RCS) reduction properties is proposed and studied in this paper. This antenna is a quite simple half-wavelength linear dipole right above a metasurface which consists of 9 double-head arrow-shaped unit cells arranged in a 3×3 layout. By cautiously choosing the geometrical parameters of the metasurface and tuning the distance between the dipole and the metasurface, the whole structure turns out to be a circularly-polarized antenna with RCS reduction feature. Simulation results show that the MSDA in circular polarization achieves an operating bandwidth of 410 MHz and a wide AR beamwidth of 123˚ and 90˚ in φ = 0˚ and φ = 90˚ planes respectively, together with a maximum RCS reduction of 10.4 dB in the whole operating band.
