  • Abstract
    High-impedance surfaces are studied as a means of improving the radiation pattern symmetry in aperture antennas. Compared to a solid metal ground plane, the results suggest that high-impedance surfaces can significantly improve the axial ratio of circularly polarised antennas. This can be used to reduce interference between left and right polarisation components.
