Analytical modeling demonstrates enhanced path gain in ear-to-ear on-body systems, highlighting efficient antenna radiation pattern optimization.
The versatility and computation efficiency of an analytical propagation model for on-body communication is presented. The model is used to maximize the on-body path gain by on-body radiation pattern optimization. The reduced calculation time of the model, allows for such a study to be performed. It is found that the direction towards the front of the head is favored in terms of directivity of the radiation pattern. The prediction accuracy is demonstrated to be improved, by adopting an advanced on-body far-field formulation in the calculation of the antenna gain and electric field phase. It is seen that the accuracy of the model is improved by several decibels.
