Nowadays, downfall accidents of baby and infant are increasing. It is entertained that enlargement of the accidents, since high-rise apartment increase. Using effective monitoring system is necessary to prevent the accidents. However, baby and infant are exposed in electric field using ordinary wireless monitoring system. In this paper, LF band RFID(Radio Frequency Identification)is used as a marker and a sensor for monitoring. RFID is a sort of radio beacon system. In the system, signal sending time length from the marker is limited under approx. 10 ms. Helical sensor antenna is also used in the proposed system to prevent the exposure. However, detected distance of the marker is reduced in the condition, since it is difficult that the electric field of helical antenna is not extended in its outside. In this paper, enough distance is kept to realize suitable specification of marker antenna for baby and infant. Using the proposed system, baby and infant are protected from the unexpected accident in home.
