【摘要】 本文提出了一种太赫兹可重构透射阵,该阵列工作在145 GHz,由15×15个单元组成。该阵列的单元主要由石英玻璃和砷化镓肖特基二极管构成,通过控制两个肖特基二极管的工作状态来改变元件辐射片上的电流方向,进而可以获得180°的相位差。在完成单元设计后,根据天线阵相关原理设计了一个15×15透射阵列。通过H FSS电磁仿真软件对该阵列进行仿真,仿真结果表明,由上述单元组成的透射阵可以在5 0°范围内改变波束方向,最大孔径效率为25.2%。更多还原

【Abstract】 This paper presents a subterahertz reconfigurable transmission array,which operates at 145 GHz and consists of 15 × 15 cells.The unit of the array is mainly composed of quartz glass and gallium arsenide Schottky diodes.By controlling the working state of the two Schottky diodes,the direction of the current on the element radiation plate can be changed,and the phase difference can be obtained by 180°.After the unit design is completed,a 15 × 15 transmission array is designed according to the principle of antenna array correlation.HFSS electromagnetic simulation software is used to simulate the array,and the simulation results show that the transmission array composed of the above elements can change the beam direction in the range of 50°,and the maximum aperture efficiency is 25.2%.更多还原
