摘要

在本文中，我们使用一个可重构的端火天线单元，具有四个波束方向，形成一个均匀的线性阵列，有18个元素。在工作状态下，阵列在方位角上的最大扫描范围为70度。为了消除天线阵的背辐射，实现波束在仰角方向的偏转，我们设计了与天线工作频带相对应的人工磁导体(AMC)，并在AMC结构的贴片之间增加4个PIN二极管状态，使AMC单元的反射相位可以重构，从而改变端射天线阵的最大波束方向。使天线阵在仰角方向上进行扫描。

Two-dimensional Wide-angle Scanning of End-fire Linear Array Based on Reconfigurable AMC

In this paper, we use a reconfigurable end-fire antenna unit with four beam directions to form a uniform linear array with 18 elements. The array has a maximum of 70 degrees scan range in the azimuth under a working state. In order to eliminate the back radiation of the antenna array and achieve beam deflection in the elevation direction, we designed an artificial magnetic conductor (AMC) corresponding to the working frequency band of the antenna, and added four PIN diodes states between the patches on the AMC structure to make the reflection phase of AMC unit can be reconstructed, thereby changing the maximum beam direction of the end-fire antenna array, so that the antenna array can scan in the elevation direction.
