摘要

A row of crossed dipoles (1 . . . i. . . n) for circular polarisation is mounted upon a flat reflector (11) which serves to reflect horizontal polarisation components and which supports, at equal spacings at each side of the dipole row, conductor elements (21, 22) which are designed for reflection of vertical polarisation components by forming the reflector as a corner reflector. The height of the conductor elements (21, 22) above the reflector 11 is conveniently smaller than one half of the operating wave length; the spacings of said elements (21, 22) are advantageously 0.45 of operating wave length.
