Abstract
A uniform geometrical theory of diffraction (UTD) ray analysis of a 60-GHz compact-range Gigabit wireless access system in the presence of the platform and human body is presented in this paper. The field radiated by a large array antenna, which is the source of the system, is represented by a collective UTD solution consisting of just a few rays emanating from specific points in the interior and on the array aperture boundary. These UTD rays can be interpreted as the Floquet waves and their diffractions at the edges and corners of the array boundary. They are traced to interact with the platform and human body based on the UTD method for predicting scattering effects. Numerical results are presented to show the efficacy of the present UTD approach for analyzing the system.
