A circular phased array antenna that can generate orbital angular momentum (OAM) radio beams in the 10 GHz band is described. The antenna consists of eight inset‐fed patch elements and a microstrip corporate feeding network. A full‐wave electromagnetic simulator is used to aid the antenna design and theoretical simulations are confirmed by measurements.
