Abstract
A near field meanderline like antenna assembly is disclosed which is configured to read an RFID label. The antenna is configured as a single and continuous conductor and is configured to extend from one end of a substrate forming a feed point to another end of a substrate forming a termination point. The termination point is connected to a ground through a resistor and the conductor is configured to direct current in two dimensions along the conductor. A localized E field directs a current distribution along an effective length of the antenna corresponding to a half-wave to a full-wave structure.
