摘要

本文提出了一种用于无线传感器网络定位系统的简单开关波束天线系统。元素模式是根据需求选择的。制作了一个简单的波束形成网络并进行了测试。在无界自由空间中对系统的天线方向图进行了数值计算，并与室内环境下的测量结果进行了比较。结果表明，该系统在室内环境中提供了空间多样性。这种空间分集可用于定位算法，提高定位精度。

A simple switched beam antenna system for a beacon node localization in wireless sensor networks

This work presents a simple switched beam antenna system for the localization system in wireless sensor networks (WSNs). The element patterns are chosen for the requirements. A simple beamforming network is fabricated and tested. The antenna patterns for the system are numerically computed in unbounded free space and compared with the ones measured in the indoor environment. The results show that the system provides space diversity in the indoor environment. This space diversity can be used in the localization algorithm to improve its accuracy.
