IEEE Transactions on Antennas and Propagation. ISSN: 0018-926X. Vol. 60, nr. 3 (2012), pp. 1634-16380018-926Xhttp://hdl.handle.net/10400.21/5091A pentagonal patch-excited sectorized antenna (SA) suitable for 2.4-2.5 GHz localization systems was studied and developed. The integration of six patch-excited structures converges into a sectorized antenna called Hive5 that provides gain improvement compared to a patch antenna, maximum variation of 3 dB beam width over the radiation pattern and circular polarization (CP). This antenna is presented and analyzed taking into account the tap length and the flare angle. The proposed antenna in combination with a RF-Switch provides a cost effective solution for localization based on Wireless Sensor Networks (WSN) and will be used for implementing angle of arrival (AoA) techniques combined with RF fingerprinting techniques.engAngle of Arrival (AoA)Axial Ratio (AR)Hive5Localization System (LS)Patch-Excited StructureReceived Signal Strength (RSS)Sectorized Antenna (SA)journal article10.1109/TAP.2011.2180339
