Antenna for RFID smart table

Abstract

Smart table represents the ability of a table to detect items placed on it by using RFID technology. The position as well as certain activities of these items could be tracked as RFID tags embedded into these detected items have a unique identification number depending on the chip integrated with the tag. Hence, the table can determine the position and existence of each specific item on it with time. In this paper, the antennas applied in high frequency (HF) RFID smart table applications was addressed. The HF antennas with different sizes are investigated to generate uniform field distribution in an interrogation region.
