Characterization of on-body communication channel for vertical and horizontal polarization of center fed dipole at GSM frequency

While designing a wearable antenna for on-body communications, particular importance is given to lessen the lossy effects of the human body on transmission coefficient. This paper presents experimental and simulation results for two different polarizations of center-fed dipole antenna on human body at mobile communication frequency. The isolated parameter is S₂₁(dB). Early results suggest that vertical polarization of dipole gives better transmission coefficient than horizontal polarization.
