Wearable Conformal Antennas for 2.4 GHz Wireless Body Area Networks
Abstract: Microstrip fed inset
patch antennas embedded in planar and cylindrically curved surfaces are
introduced to be used in Body Area Networks (BANs) presented. These antennas
are designed as wearable antennas for industrial, scientific and medical (ISM)
band wireless communication networking. The proposed antennas consist of 50 Ω
microstrip line feeding inset patch printed on the front face of dielectric
substrate and a rectangular ground plane on the bottom face. The proposed
planar antenna is conformed on finite cylindrical substrates of radii 2.5, 5
and 7.5 cm corresponding approximately to the typical size of human wrist,
humerus and shoulder of a human body respectively. Modeling and performance
evaluation of the cylindrical structures has been carried out using the
commercially available electromagnetic software CST Studio Suite2009.
Simulation results, obtained for the return losses, current distribution, and
radiation pattern of the antennas are presented. Furthermore, results show that
the designed conformal antennas are resonating at the designed frequency with
reasonable gain and field pattern characteristics.
