Variability in the fabrication process and uncertainty in deployment conditions complicate the design of wearable antennas. In this contribution, we present an overview of adapted design strategies to account for such random effects. Conventionally, overspecification of the antenna requirements accommodates for unexpected variations and, as such, ensures appropriate performance in all operational...
Given the growing interest in wireless power transfer, there is a need to quickly evaluate the efficiency of such links for different power source and receiver separations and orientations. Moreover, a designer is not only interested in the nominal operating conditions, but also in the variations encountered due to variability and uncertainty in the system parameters and deployment conditions. We...
A stochastic framework is proposed to evaluate the effect of random effects on the overall performance of wireless links. A generalized polynomial chaos expansion is leveraged to relate the uncertainties in antenna geometry, orientation and position to the figures of merit characterizing the link. The stochastic testing procedure is proposed as a more efficient alternative to stochastic collocation,...
