This confirms my assessment that L band radar on leading edge can only provide azimutal beam steering, and no control in elevation. Obviously with just one patch antenna in the row the beam amgle in vertical plane will be quite wide. In no case narrower than ~ +/- 15 degrees.



This Array CAN BE part of stealthy aircraft.









and this image shows 12 element array (presumably L band, each encased in metal walled enclosure to provide isolation with adjacent element (vital for beam steering), with common services for the AESA elements provided by bigger modules located aft of the array.



BUT this AESA array IS NOT stealthy at all.
