On the stochastic characterization of wearable antennas

Wearable antennas for body centric communications, which can operate in the frequency range from VHF to UHF and UWB bands, are reviewed. Their distinctive requirements are highlighted, which are quite di®erent from those required to more conventional antennas for mobile terminals, access points and base stations. Also, speci¯c attention is devoted to those parameters that can be used to characterize such class of antennas, since their characterization needs for a stochastic approach that can account for performance variations associated to the natural movements of the person wearing the wireless device
