1. An antenna, comprising:
- a radiator aperture assembly including a plurality of radiator sticks arrayed side-by-side in a first direction, each radiator stick being elongate in a second direction transverse to the first direction and including a row of radiating elements configured to transmit and receive RF energy and a body having opposite sides,the row being extended along the second direction and each of the radiating elements being elongate in the first direction;
conductive elements coupled to the radiating elements; and
a plate disposed proximate to the radiator aperture assembly through which the conductive elements extend,complementary opposite sides of the respective bodies of adjacent radiator sticks and a surface of the plate being configured to form a slot radiator that is elongate in the second direction and into which corresponding ones of each of the radiating elements are disposed to extend in the first direction.

Abstract
An antenna is provided and includes a radiator aperture assembly including a plurality of radiator sticks, each radiator stick including a row of radiating elements configured to transmit and receive RF energy and a body having opposite sides, conductive elements coupled to the radiating elements and a plate disposed proximate to the radiator aperture assembly through which the conductive elements extend. Complementary opposite sides of the respective bodies of adjacent radiator sticks and a surface of the plate are configured to form a slot radiator.

11. An antenna, comprising:
-
a radiator aperture assembly including a plurality of radiator sticks arrayed side-by-side in a first direction, each radiator stick being elongate in a second direction transverse to the first direction and having conductive elements electrically coupled to circulators, the conductive elements being arrayed along the second direction and respectively elongate in the first direction and; and a plate through which the conductive elements of each of the plurality of the radiator sticks are extendible, the radiator aperture assembly and the plate being attachable to one another such that adjacent radiator sticks define chamfered and notched radiator slots extending forwardly from the plate and elongate in the second direction. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. An antenna, comprising:
-
a radiator aperture assembly including a plurality of radiator sticks arrayed side-by-side in a first direction, each radiator stick being elongate in a second direction transverse to the first direction and having pairs of conductive elements each respectively electrically coupled to one of a pair of mirrored circulators, the pair of conductive elements being arrayed along the second direction and each conductive element being elongate in the first direction and; a plate through which the conductive elements of each of the plurality of the radiator sticks are extendible; and a coldwall into which the conductive elements of each of the plurality of the radiator sticks are extendible and connectable with corresponding transmit/receive modules; the radiator aperture assembly and the plate being attachable to one another such that adjacent radiator sticks define radiator slots extending forwardly from the plate and elongate in the second direction. - View Dependent Claims (19, 20)
