Active electronically scanned array antenna
First Claim
1. An antenna, comprising:
- a plate; and
an aperture assembly attached to the plate,the aperture assembly comprising a plurality of radiator sticks arrayed side-by-side in a first direction with each one of the plurality of radiator sticks being elongate in a second direction transverse to the first direction and respectively comprising;
a spacer;
a carrier formed separately from the spacer and on which circulators are disposed, each circulator comprising a substrate, a conductive layer disposed on the substrate and a magnetic element disposed on the conductive layer;
a base defining recesses from which bosses interleaved with the recesses protrude; and
fasteners disposed to fasten the spacer to the base at locations of the bosses with the carrier interposed between the spacer and the base and with the circulators aligned with the recesses,the antenna further comprising conductive elements extending through the plate and the base for electric coupling to the circulators,wherein adjacent ones of the plurality of radiator sticks are configured to cooperatively define a slot that extends along the first direction and forwardly in a third direction transverse to the first and second directions from the plate and which is notched and curved forwardly in the third direction at and from the corresponding circulator.

Abstract
An antenna is provided and includes a plate and an aperture assembly attached to the plate. The aperture assembly includes sticks that respectively include a spacer, a carrier formed separately from the spacer and on which circulators are disposed, a base defining recesses from which bosses interleaved with the recesses protrude and fasteners disposed to fasten the spacer to the base at boss locations with the carrier interposed between the spacer and the base and the circulators aligned with the recesses. The aperture assembly further includes conductive elements extending through the plate and the base for electric coupling to the circulators. Adjacent sticks define a slot extending forwardly from the plate. The slot is notched at a corresponding circulator and rounded forwardly from the corresponding circulator.
