1. A wideband phased array antenna comprising:
a plurality of antenna cells, one or more of the antenna cells comprising:
a driven element disposed on a first substrate, the first substrate comprising a first dielectric material; and
a parasitic element disposed on a second substrate to provide a stacked patch topology, the second substrate comprising a second dielectric material, the second dielectric material being different than the first dielectric material,
wherein an area of the driven element is smaller than an area of the parasitic element.
