Abstract
The unique properties of fractals have been exploited to develop a new class of antenna element designs that are multi band and compact in size. These properties are very important for RFID (Radio Frequency IDentification) tags where the small size, planar geometries, multi band operation and low cost are essential for many applications. This paper presents a one loop Minkowski modified antenna using a unique configuration and operating at 868MHz and 2.45 GHz that has been realized on a Rogers Duroid substrate. Experimental results confirm the theoretical prediction. In addition, the principle applied in this design could be used to create even smaller devices by using different substrates.
