ABSTRACT:
A layered antenna having a linear array of radiating elements (11) is disclosed. Each radiating element comprises an aperture with one or more probes (16,18) which extend into the area defined by the apertures in two groundplanes parallel spaced from the probes and feed network (14) therefor. There is provided a reflecting backplane (28) which serves to reflect signals directed towards the backplane back toward the probes whereby the output signal in the primary radiating direction is reinforced. Flanges (30,32) depend from the apertured groundplane closest to the reflecting groundplane to isolate the radiating elements and thereby reduce coupling effects.
