Much interest is currently being shown in mm-wave high data rate, short range communication links. The modelling of these types of links presents considerable challenges. In this paper, a 60 GHz link consisting of two Cavity Backed Slot antennas, the terminals on which they are mounted and the intervening environment, is modelled using an enhanced FDTD technique. This type of problem can be expensive in computer resources because of the existence of small geometrical detail and also a large computational space. To improve on this, the problem is split into three parts which are linked using a Time Domain Huygens (TDH) approach. An improvement of around 56 % is obtained in the overall run time compared to a direct FDTD run. The approach has much potential and is suitable to be applied in larger and more complex communications links.
