RFID Tag Antenna Attached to Drug Nozzle and Electronic Fishing Float

In this paper, we suggest an RFID tag antenna for ultrahigh frequency band for radio frequency identification for drug runout management and a float motion detection that can be used in hospitals and fishing. The RFID tag antenna works as a sensor which warns of drug runout when the drug inside the drip chamber is completely consumed, while it does not work if the drug remains inside the drop chamber. Also, the antenna which attached to the fishing float propagates signals when it is exposed to air, but it does not work when submerged in water. The fabricated antenna has an average omnidirectional reading range of 10.65 m in the horizontal plane.
