ABSTRACT In this paper, a novel pattern steerable antenna array with a scanning range of 60° and operating at 2.45 GHz is proposed. The antenna array can change the direct current (DC) of the material by introducing ferroelectric material as a substrate. The DC of the ferroelectric material is changed by external direct voltage bias, which realizes the continuous change of the feed phase of units. The antenna array consists of four parts of feed structure, isolation structure, phase shifters, and antenna array elements. They are integrated into the two metal layers on both sides of the floor. Unlike other antennas, the antenna can change the maximum radiation range from −30° to 30° only by controlling the magnitude of the external DC bias voltage. In addition, a novel DC bias circuit is designed, which reduces the design complexity of the antenna and improves the practical value.

一种基于外场的新型可控天线

摘要 在本文中，提出了一种扫描范围为 60°、工作频率为 2.45 GHz 的新型方向图可控天线阵列。天线阵列可以通过引入铁电材料作为基板来改变材料的直流电（DC）。通过外部直流偏压改变铁电材料的直流电，实现单元馈电相位的连续变化。天线阵列由馈源结构、隔离结构、移相器和天线阵元四部分组成。它们集成在地板两侧的两个金属层中。与其他天线不同的是，该天线仅通过控制外部直流偏置电压的大小就可以将最大辐射范围从-30°改变到30°。此外，还设计了一种新颖的直流偏置电路，
