Abstract: Biomedical telemetry system transmits biological
signal to a long distance. Antenna finds vital role in transmitting a
biological signals. Patch Antennas are integrated with medical devices and
used widely because of their design flexibility and shape. This paper
proposes two antennas for telemetry application. Yagi antennas provide high
directivity. Patch antennas are of light weight and is easy to carry. It can
be fabricated on the fabric easily. Hence it proves to be an ideal solution
for biotelemetry where the patients can wear the antenna, which in turn can
collect the bio signals from the body and send it to the monitoring station.
This combination of yagi and patch antennas gives sufficient gain and
directivity his paper proposes the design of two Yagi Patch Antennas (YPA)
with two different substrates for telemetry purpose. A miniature telemetry
antenna model is designed, which captures information from the human body
and transmits it to the monitoring station. The biological information is
transmitted at a frequency of 2.45 GHz. in WLAN range. The performance of the
antenna is simulated and analyzed using FEKO software.
