Abstract
A wideband phased array antenna is provided. The wideband phased array antenna includes a plurality of antenna cells. Each of the antenna cells is configured to communicate over a frequency band ranging from 24 GHz to 52 GHz. Furthermore, one or more of the antenna cells includes a driven element and a parasitic element. The driven element is disposed on a first substrate that includes a first dielectric material. The parasitic element is disposed on a second substrate positioned relative to the first substrate such that a gap is defined between the first substrate and the second substrate. The second substrate includes a second dielectric material that is different than the first dielectric material.
