2085131 9120109 PCTABS00009 Various modifications and improvements are described relating to planar microwave antennas of the type formed from a plurality of moulded planar layers. The antennas comprise a first layer (10) forming an array of horn elements, and one or more underlying layers (12, 14) define guide channels (62, 64) communicating with the horn elements. The improvements include the following: the channels formed in the underlying layers are open-topped, being closed along the majority of their length by abutment with the lower surface of the previous layer; the surfaces of the channels and the horn elements being metallised; the abutting surfaces are formed with complementary locating ribs and grooves and the layers are secured together by rib welding; the guide channels may be formed at the interface between layers by aligned channels in the upper and lower surfaces of the layer in abutment; and the central axes of the horn elements may be disposed at an angle to the plane of the antenna.
