Abstract
We propose a single-polarized ultra-wideband element for mm-wave phased arrays. The element is comprised of tightly-coupled bowties fed by a specific configuration of plated via holes. The corresponding feeding network is implemented in such a way to eliminate the use of an external balun. In addition, it provides the possibility to be manufactured by PCB technology. The simulated element has a relative bandwidth of 2.56:1 at a reflection coefficient better than -8 dB while scanning up to 45°. The reflection coefficient remains below -6 dB for a maximum scanning angle of 60°.
