Abstract
A self-complementary patch antenna is disclosed. A hexagonal lattice () consisting of triangular conducting patches () is formed together with at least one dielectric layer onto a ground-plane. Each triangular patch is then fed by means of three RF signal probes in a symmetrical configuration positioned near each corner of the triangle, whereby an arbitrary lobe-steering and polarization state can be established by selection of amplitude and phase for each RF signal probe.
