ABSTRACT:
Planar microwave antennas are described of the type formed from a plurality of moulded planar layers. A first layer defines horn elements and two underlying layers define waveguide channels communicating with the horn elements. The waveguide channels are formed at the interface between layers by aligned channels in the abutting surfaces. The surfaces of at least the horns and waveguide channels are metallised, and the layers may be secured together by rib welding.
