14. A phased array antenna system comprising:
a flexible printed circuit board formed of a flexible material, the flexible printed circuit board comprises a component layer, an antenna layer, and a phase matching layer between the component layer and the antenna layer;
a single control unit including one more processors coupled to the component layer;
a plurality of antenna elements coupled to the antenna layer;
at least one first ground layer disposed between the component layer and the phased array matching layer;
at least one second ground layer disposed between the antenna layer and the phased array matching layer;
a plurality of radio frequency (RF) fences disposed within the antenna layer, wherein each of the RF fences is associated with a respective one of the plurality of antenna elements; and
a plurality of signal paths extending through the component layer, the phase matching layer, and the antenna layer, wherein each of the plurality of signal paths connects the single control unit to a respective one of the plurality of antenna elements, and wherein each of the plurality of signal paths has an equal length.
