Antennas and Propagation for In-Mouth Tongue Controlled Devices in Wireless Body Area Networks

Research output: Contribution to journalArticle

Abstract

Tetraplegic patients have to depend upon someone
else for moving the wheelchair or typing on a computer. One of
the ways to make them independent is by using tongue-controlled
in-mouth wireless devices. This letter presents antennas and
propagation for such devices in 2.45 GHz ISM band. A monopole
and a loop antenna suitable in size and performance is presented
for such devices. The propagation link between the in-mouth
antenna and an external antenna is measured by mimicking the
use-case scenarios of such devices by placing an external antenna
on a laptop, and on a chair. The link loss is found to be in the
range of 55-75 dB depending upon the antenna type and the
scenario. Using these values of the link loss, a reliable link can be
established between the in-mouth device and the external device
either mounted on a wheelchair or a computer.
