摘要：
A low cost dual polarized 3D printed digital meta-surface transmitarray antenna for mm-wave applications is presented in this paper. The unit cell element is composed of a dielectric prorated elliptical cylinder with a square base. The height of the elliptical cylinder is varied to control the transmission phase of the incoming electromagnetic wave. Four quantized phase state (00, 01, 10 and 11) are obtained by varying the height of the unit cell. A 4.5 lambda(omicron) x 4.5 lambda(omicron) transmitarray is deigned and illuminated by the wide-band 3D printed horn antenna. The measured results show a wideband performance with a 3 dB gain bandwidth of 33 %. A measured peak gain of 20 dBi is obtained at 30 GHz corresponding to an aperture efficiency of 38%.
