Abstract :
A novel model of the pinna (outer ear) is presented. This is to increase the understanding of the effect of the pinna on the on-body radiation pattern of an antenna placed inside the ear. Simulations of the model and of a realistically shaped ear are compared to validate the model. The radiation patterns, including the phase and gain, and the radiation efficiency are compared.
