KHATTAK, M.I. ... et al, 2010. A study of perturbations in linear and circular polarized antennas in close proximity to the human body and a dielectric liquid filled phantom at 1.8 GHz. IN: Proceedings of the Fourth European Conference on Antennas and Propagation (EuCAP 2010), Barcelona, Spain, 12th-16th April.
In the design and synthesis of wearable antennas
isolation distance from the body is a critical parameter.
This paper deals with the comparison of perturbations caused to
the matching of simple linear and circular polarized patch
antennas due to the close proximity of a human torso and
rectangular box phantom filled with muscle simulating liquid at
1.8GHz. The isolated variable is return loss (S11). Results show
that both linear and circularly polarized antennas produce an
optimal return loss closer to the surface of a typical phantom
than the back of a human volunteer.
