Abstract
A planar phased array antenna assembly includes a first face sheet with a first plurality of radiating slots for a first frequency band and a second plurality of radiating slots for a second frequency band, a second face sheet, a third face sheet, and a structure interposed between the first and second face sheets with a third plurality of radiating elements at the first frequency band and a fourth plurality of radiating elements at the second frequency band, and a first feed network for the third plurality of radiating elements and a second feed network for the fourth plurality of radiating elements, and the second face sheet interposed between the structure and the third face sheet. The planar phased array antenna assembly may form part of a synthetic aperture radar (SAR) antenna.
