Moreover, the length of the dipole (L) should be increased for conjugate matching with an RFID chip. A previously proposed 915 MHz dipole antenna, is too large to be attached to the drip chamber of a feeding bag. The RFID tag antenna is designed to function as a sensor that alerts drug runout when a drug inside a drip chamber is completely consumed but does not work when a drug remains inside a drop chamber. This article proposes an ultrahigh frequency band radio frequency identification (RFID) tag antenna for drug runout management that can be used in hospitals. These results are comparable with those of non-portable RFID readers on the market. The minimum received-signal-strength indicators (RSSIs) for LOS and NLOS are found to be −63.75 and −59.66 dBm, respectively. The proposed RFID reader can read passive tags with distances up to 12 and 5.5 m for line-of-sight (LOS) and non-line-of-sight (NLOS) communication, respectively. The reader is designed using low-cost devices widely available on the market for ease of duplication and assembly by researchers, educators, and startups.

To overcome this problem, this paper proposes a portable RFID reader built to an ISO 18000-6C standard to extend the sensing area due to its moveability. The greatest challenge of RFID-reader technology is its short communication range, which limits the sensing area. To access the user memory bank, an RFID reader should comply with ISO 18000-6C standards. RFID has been used not only for identification but also for carrying information, which is stored in a user memory bank attached to the tag. Many communications technologies have been applied to SBEM, including radio-frequency identification (RFID). In order to illustrate this improvement, a monitoring system layout prototype is proposed.Ĭommunication is an important factor in smart-building energy management (SBEM). Comercially available system used as reference is composed by a reader CSL 461 and passive tag Confidex Carrier. The second antenna is fabricated on Rogers Duroid 5880 flexible substrate allowing adhesion to any surface shape, a read range of 6m is obtained. The first antenna is implemented on printed circuit board (PCB) obtaining a read range of 8.25m, a read range improvement of 2.25m is observed compared with commercially available passive systems. This work presents the design of two UHF RFID meander line antennas for newborn hospital monitoring applications. Ultra High Frequency Radio IDentification (UHF RFID) brings an easy and cheap solution to this problematic because of automatic real time control and monitoring of passive elements called tags. However, CCTV needs human operator and a highly implementation cost. Closed Circuit Television (CCTV) surveillance is one of the most used solutions. Theft and exchange of newborns have rise its numbers becoming this topic a big issue that must be face up by hospitals.
