The technology has grown significantly supporting a range of applications in
every sectors such communication and medical sectors. Wireless Body Area Network(
WBAN) is a one of the innovation. WBAN is a special purpose sensor network
designed to operate autonomously to connect various sensors and appliances.
One of the component for WBAN is data base external to perform its transmitting
and receiving the data from the sensor with its antenna.
Data base external of WBAN needs the antenna that can be compatible for its
device. The antenna has to be small dimension, light weight, ease realization, and
low profile specification that can be beneficial in the implementation of antenna
for WBAN and save for human body. The antenna has to work on two resonance
frequencies, 900 MHz and 2.4 GHz for WBAN configuration. Based on existing
PIFA research, PIFA is a microstrip antenna that can be designed to be a multiband
antenna, work in wide range frequency, and decrease the occupancy required
area. The addition of U-slot is also needed to make a multi-band frequencies. PIFA
antenna can fulfil the needs for data base external of WBAN.
This undergraduate thesis focused on design, simulate, fabricate, and measure
the PIFA for WBAN’s data base external antenna with a Dual-Band frequency. This
PIFA is focused where the resonance frequency are 900 MHz and 2.4 GHz, and also
return loss is less than -10 dB. The result that obtained on this undergraduate thesis
is fulfilled the requirement, but the resonance frequency got shifted to 820 MHz and
2.37 GHz with its return loss -16 dB and -19 dB.
