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 Suite 2009.
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. |
