Independent phase and amplitude controlled transmitarray antenna with high gain and low sidelobes

Abstract

A novel transmitarray antenna (TA) consisted of the element which is proposed to achieve the capability to control the transmission phase and magnitude independently by simply changing two geometric parameters of it. The structure works as the element of the TA can cover 360°phase range and the desired magnitude distribution. The advantages of this design are more flexibility to adjust the phase and magnitude to enable the TA to get high gain and low SLLs directly and efficiently. The simulated results verify the design concept.
