Abstract:
This research paper deals with a low SAR patch
antenna that resonates at 2.415 GHz. This antenna can be
employed to monitor the pacemaker system wirelessly,
considering its performances. The main aim was to operate the
antenna at ISM (Industrial, Scientific and Medical) band (2.4–
2.48 GHz) in the pacemaker system, where body granted
materials were used to construct both the pacemaker and the
antenna to ensure the biocompatibility. To investigate the
antenna parameters’ changes between free space and in-side
body condition, the designed antenna was examined and
compared for both conditions. The key speciality of this design
is that the SAR (Specific Absorption Rate), which is the most
crucial parameter for any in-body antenna, was found in a
considerable-safe region. Moreover, Computer Simulation
Technology (CST)-based desired findings of this antenna for
return loss, VSWR, and far-field radiation characteristics were
found with compared to other recent body-implantable
antenna related published works.
