The location estimation capability of a RFID (Radio Frequency IDentification) technology is useful for indoor navigation systems on mobile robots. In this paper, the authors study a simple and small structural antenna at 2.5GHz band that can reduce the beam when installed on a mobile robot. An antenna with small occupation volume by a mechanical rotation is assumed. They used electromagnetic field simulation and experimental results to design a simple structural antenna. Their design culminates in two antennas comprised of Tetragon elements formed with wires. One is called Tetra-4 and is an antenna which has a lateral arrangement of four tetragons.
