Abstract: A phased array antenna system having radiating units unitarily formed and arranged in an array by direct metal sintering avoiding assembly requirements. Each radiating unit includes a free-space impedance transformer having first, second and third radiator elements. Each radiating unit includes an embedded balun having first, second, and third impedance transition elements located generally concentric with the first, the second, and the third radiator elements and distally connected respectively to form a first integrated coaxial interface, a second integrated coaxial interface, and an integrated ground interface. Each radiating unit includes a ground plane electrically coupled to the integrated ground interface.
