| description | Recently, there is a growing demand of healthcare monitoring for elder people.
Therefore, wearable antennas become the best solution to monitor elderly’s body.
Fabric is considered the most suitable material for body wearable applications due to
its flexibility this type of antenna textile or fabric based which has the characteristics
of wearable microstrip patch antenna such as light weighted, easily attached to the
body of senior person and low cost. A wearable microstrip patch antenna operating at
single frequency 2.45 GHz had been designed. Therefore, the geometry of the patch
antenna is 51 mm (L) × 56 mm (W) while the ground plane and substrate dimensions
are 73 mm (L) × 73 mm (W). The substrate material used for this project is felt with a
height of 1.1 mm and dielectric constant of 1.38 and copper for radiating element. The
simulated return loss S11 of the microstrip patch antenna is -34.011 dB at 2.45 GHz,
while the measured S11 is -19.507 dB at 2.44 GHz. In conclusion, the simulated SAR
confirms that the antenna is wearable, with 0.4755 W/kg at 2.45 GHz. Furthermore,
the bending effect of the antenna with radius from 36 to 126 mm and its SAR was
analysed. The SAR value of the antenna was tested, based on flat and bended antenna
to show the radiation effect on the human body phantom. The bended SAR value
shows 0.702 W/kg at 2.45 GHz. The SAR values of both antennas are safe according
to the International Commission on Non-Ionizing Radiation Protection (ICNIRP),
European standard. The standard safe level is 2 W/kg for any 10 grams of tissue. The
antenna performance was measured using Vector Network Analyzer. The simulated
and measured results shown a good agreement only on the frequency but shows
different results on the return loss. |
