Overlapping subarray architecture

摘要: An embodiment of an electronically scanned array antenna includes radiative elements having height. A plurality separate subarrays the include a first row comprising subarrays, wherein are horizontally non-overlapping with one another, and second subarrays. The arranged vertically adjacent to row, another. not shared any other subarray. have subarray heights which smaller than In another embodiment, method for suppressing grating lobe formation in steered applying illumination function subarray; is different from function.
