Abstract :
We study in this paper the design of circularly-polarized (CP) patch antennas on a reactive impedance substrate (RIS). Dual- and single-feed patches are considered. The characteristics are compared with those of a single-layer antenna and the corresponding dual-layer antenna. Numerical results are confirmed by experimental ones. A wideband CP patch antenna on the metamaterial substrate is designed.
