FDTD ANALYSIS OF WIDE-BAND APERTURE-COUPLED INTERCONNECT

Recent developments in high speed chip modules, multilayer printed cir cuit boards and aperture coupled phased microstrip patch antenna array s require wideband and cost effective interconnections in frequency ba nds that are steadily moving upwards in the gigahertz range. The conce pt of a microstrip aperture coupled interconnect is proposed by the au thors and investigated using Gabor excitation in the finite difference time domain (FDTD) and verified through measurements. The surprisingl y ultra-wideband and efficient performance of the interconnect and the simplicity of its implementation, mean that it can replace many of th e interconnects presently in use.
