Abstract
A flexible wire radiating element for a body-worn antenna has a length that meets a specified absorption rate (SAR) for a given transmit power, nominal frequency, and separation distance, and allows a higher transmit power than that achievable with a half wavelength element but is within substantially one decibel of efficiency. Using a plot of SAR over length, a minimum length necessary to meet the SAR limit is then mapped to a length corresponding to a peak in a horizontal efficiency plot.
