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.

Patch antenna

A dual polarized wave-guide notch antenna array is disclosed. The device comprises a feed section having at least two input transmission lines, a feed/wave-guide interface providing an aperture for transferring a radio frequency electromagnetic wave between the feed section and a wave-guide mode in a wave-guide section having ridges. The wave-guide section transfers energy between the feed/wave-guide interface and a tapered notch section, thereby gradually adjusting a created electromagnetic field towards free space conditions.
