    Abstract: The location estimation capability of a RFID (Radio Frequency Identification) technology is useful for indoor navigation systems on mobile robots. In this paper, we 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... Show More
