Abstract :
This paper proposes a novel transmitarray element consisting of 3-layer identical E-shaped metal patch. Several transmitarray elements of different shapes are analyzed. The E-shaped unit is developed to alleviate the cross polarization level in this linear-polarized transmitarray design, and a smooth phase curve is obtained. Through simulation, the proposed 3-layer E-shaped unit reaches a phase range of 270 degrees above -1dB transmission magnitude, and an average 50dB cross polarization discrimination.
