摘要

提出了一种亚太赫兹反向定向天线阵列。该阵列接收40 GHz导航信号，并在到达波方向精确重传120 GHz波束。仿真结果表明，叠置夹层结构阵列实现了对到达波的跟踪。扫描辐射图显示，当入射角为20°时，阵列在19.9°处的增益为23.87 dB，相对误差仅为0.5%，即在传输距离为5公里时，横向误差仅为8.7米。

A Sub-Terahertz Retrodirective Antenna Array for Satellite Tracking

A sub-terahertz retrodirective antenna array is proposed. This array receives 40 GHz navigation signal and accurately retransmits 120 GHz beam in the direction of arrival wave. Simulation results indicate that proposed array with stacked sandwich structure has realized the tracking of the arrival wave. The scanning radiation pattern shows array gain is 23.87 dB at 19.9° when incident angle is 20° with a relative error of only 0.5%, which means there is a lateral error of only 8.7 meters at a transmission distance of 5 kilometers.
