Abstract :
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.
