摘要

本文研究了一种基于2.45 GHz微型化贴片天线的智能波束引导技术。天线是小型化的，在贴片上有一个不对称的插槽，大大降低了操作频率。在具有相同介电特性的工作频率下，它的辐射面积为传统贴片的23% (0.15 \lambda X 0.11 \lambda， \lambda$为2.45 GHz的自由空间波长)。1 × 8天线阵列还设计了一个功率分配器和移相器电路，以演示波束转向操作。通过数值研究，在方位面上观察到的最大转向角为220。

Smart Beam Steering with a Slot-Loaded Miniaturized Patch Antenna

In this paper, a smart beam steering technique is investigated with a miniaturized patch antenna at 2.45 GHz. The antenna is miniaturized with an asymmetrically placed slot on the patch that reduces the frequency of operation significantly. It radiates with $23 \%$ area $(0.15 \lambda X 0.11 \lambda, \lambda$ is the freespace wavelength at 2.45 GHz) of a conventional patch at the operating frequency with the same dielectric properties. A $1 \times 8$ antenna array is also designed with a power divider and phase shifter circuit to demonstrate a beam steering operation. With numerical investigation, a maximum of 220 steering angle is observed in the azimuthal plane.
