1. An array antenna comprising:
- at least one waveguide;
a plurality of radiating elements on said at least one waveguide whose lengths are arranged substantially parallel to a longitudinal direction of said waveguide;
and means for reducing reflection of incident radiation in a direction opposite to a direction of propagation of the incident radiation, wherein the reducing means comprises electrically conducting elements located between the radiating elements on the at least one waveguide, arranged substantially perpendicular to said longitudinal direction of said waveguide, and substantially parallel to an electrical field generated by the radiating elements.
