Based on the Pancharatnam-Berry phase principle, a wideband low-profile transmissive metasurface was designed and applied to a transmitarray antenna (TA). While a full transmission phase range of 360 degrees was achieved by rotating the proposed unit cell, the transmission coefficient was always close...
