A High-Efficiency 3D-Printed E-Band Dielectric Transmitarray For Integrated Space and Terrestrial Networks

Abstract

A highly efficient wideband transmitarray working at E band is developed in this paper. This transmitarray is composed by 10 10 dielectric cells and fabricated through three-dimensional (3D) printing technology. To obtain the required phase distribution of the array, the height of dielectric cells is adjusted. To reduce the phase error under oblique incident angles, multiple-angle phase distribution is analyzed. This transmitarray can work within a wideband from 60 to 90GHz. The peak gain can reach 23.4 dBi at 74 GHz with the maximum aperture efficiency of 60.9%.
