Abstract

Abstract: In this article, a high gain transmittarray antenna for 5G is presented. The transmittarray antenna is composed of an ultra‐thin transmitarray and its feed structure of the filtering dielectric antenna. The ultra‐thin transmitarray based on cross‐shaped metasurface is designed to realize the gradient distribution of phase covering the range of 0~2 π. The compact low temperature co‐fired ceramic dielctric antenna array feed by subtrate integrated waveguide powder divider is exploited as the feed of the transmittarray. The experimental results show the metasurface of the structure has obvious convergence effect on the radiation energy of the antenna, and the directivity of the antenna is greatly enhanced. The sidelobe energy is effectively suppressed and the peak gain of the antenna is increased from 11.47 dB to 22.8 dB at the central frequency of 28.0 GHz. The high gain and small size make the transmittarray antenna suitable for application in 5G wireless communication.
