摘要

相控阵具有较低的成本和较高的功率处理能力,对商业应用具有重要意义。在本文中,我们演示了在无固态移相器的情况下,在地平面上使用可重构周期结构的波束导向阵列。在5.6 GHz的固定频率下,实现了35/spl度/步长约6/spl度/的线性离散波束转向。在整个波束控制范围内,主波束功率变化小于2db。在5 GHz至6 GHz范围内,还实现了15/spl度/的频率相关波束导向。

A beam-steerer using reconfigurable PBG ground plane
Phased arrays with reduced cost and increased power handling capability are important for commercial applications. In this paper, we demonstrate beam-steering arrays using reconfigurable periodic structures in the ground plane without solid-state phase shifters. A linearly discrete beam-steering of 35/spl deg/ in steps of approximately 6/spl deg/ has been achieved at a fixed frequency of 5.6 GHz. The main beam power varied less than 2 dB over the whole range of beam-steering. A frequency-dependent beam-steering of 15/spl deg/ is also achieved from 5 GHz to 6 GHz.
