Procedure for Simulating the Direct Path Loss Between Body-Worn Antennas

An efficient procedure for simulating the direct path loss between body-worn antennas is presented. Nearfield sources are used to simplify the simulations and reduce the number of mesh cells. The procedure is validated with conventional full 2-port CST T-solver simulations. Next, the direct path loss between each of five different hearing solutions and a connectivity device placed on the chest are presented and discussed. Finally, it is reported that the simulation time for some of the hearing solutions is improved with up to a factor of 5.
