Abstract
This work is devoted to the study and design
of passive RFID tag antenna, this tag can be used
in biomedical applications; Essentially for detection of
the patient’s condition in a hospital. This study based on
the electromagnetic simulation results, the proposed
test is given by Computer Simulation Technology
Microwave Studio (CST-MWS) based on finite
integration technique (FIT) method. We propose a
dipole tag antenna in the 2.4-2.48 GHz Industrial
Scientific Medical (ISM) band that’s meant to be
incorporated in a wristband of a patient. The wristband
antenna in free space has a good results in terms of S11
(-33dB), gain (2.73dB), directivity (2.89dBi),
bandwidth (5.3%) and efficiency (97%). In order to study
the effect of the human body on the performance of the
antenna, this wristband will be placed on a phantom
arm. Despite the high losses introduced by the human
tissue, the antenna shows a good S11 (-17.8dB), gain
(1.31dB), directivity (4.06dBi), bandwidth (5.7%) and
efficiency (49%)
