Abstract
Nowadays Real-time localization systems (RTLS) are growing up very quickly but there are some remaining issues which need to be analyzed. This paper presents an experimental study that shows how different kind of antennas can help to reach a more accurate localization. Among all different wireless technologies, active radio-frequency identification (RFID) has been chosen due to its development and simplicity. The study has been divided into two different parts. Firstly RF tests are made to assure received signal strength indicator (RSSI) levels are the expected. Secondly measurements with different antennas have been performed. The antennas used in this study are: an Omni-directional monopole standard antenna, a Patch antenna and a 2 Patch Array antenna both in a FR4 substrate.
