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.

5G介质滤波器滤波发射阵列馈源的设计

在本文中，提出了一种用于5G的高增益发射阵列天线。发射天线由超薄发射阵列及其滤波电介质天线的馈电结构组成。设计了基于十字形超表面的超薄发射阵列，以实现覆盖0〜2π范围的相位梯度分布。由紧凑的集成波导粉末分压器馈送的紧凑型低温共烧陶瓷介电天线阵列馈送被用作发射阵列的馈送。实验结果表明，该结构的超表面对天线的辐射能具有明显的收敛作用，大大提高了天线的指向性。有效抑制旁瓣能量，天线的峰值增益从11.47 dB增加到22。在28.0 GHz的中心频率下为8 dB。高增益和小尺寸使发射阵列天线适合于5G无线通信中的应用。
