Summary In this contribution, a modular framework for ultra wide band wireless power transmission in proximity of the human body is presented. The goal of this work is to simplify the study of wireless links by considering antenna models, including radiation characteristics when the antenna is deployed on the human body, and the power transferred over them in multipath, shadowed propagation environments, such as powering textile antenna systems completely integrated inside garments. To obtain this goal, antenna links are partitioned in black box models for all elementary building blocks, such as antenna transfer functions, propagation channels, active components and more, that can be recombined as one sees fit. The recombination allows for accurate simulation of intricate systems. For small examples, considerable speed and memory gains were observed (a factor 6.20 in time and 1.75 in memory), while for more elaborate examples, it is even impossible to simulate a reference solution.
