Abstract
An antenna formed of multiple sub-arrays, each having rows of interconnected radiating elements. One row of radiating elements is shared between two sub-arrays by a coupler which isolatingly couples one row of radiating elements to each of two sub-arrays allowing the feed to the two sub-arrays to be isolatingly applied to the shared row of radiating elements while suppressing grating lobe generation and providing high sub-array isolation.
