In this paper a new technique is presented to evaluate efficiently the Green's functions of filament sources radiating over a half-space. The technique is based on the annihilation of the asymptotic and branch-point singular behaviours of the spectral Green's function. The asymptotic and singularity terms are subtracted, then calculated analytically and finally re-added to the remaining integral....
A three-dimensional antenna-in-package solution is introduced and explained in great details. The antenna is composed of three different parts: a metallic cube, an SSMA connector and antenna radiating arrays. The radiating elements are implemented and manufactured in a multilayer microwave-compatible PCB technology. The PCB includes flexible as well as rigid laminates. Having the flexible material...
A novel transition between two co-planar waveguides is introduced. The CPW transmission lines are placed in two different layers of a multi-layer PCB and connected through metallic vias. The transition shows an insertion loss better than 0.8 dB for the whole microwave V band. That makes it suitable to be used in standard 60 GHz millimeter wave communication systems.
A vertical multilayer transition for millimeter wave frequencies is introduced. The transition is implemented in IMEC multi-chip-module technology using high resistive silicon and Benzo-Cyclo-Butene as base materials. As metalized vias in high resistive silicon are difficult to achieve, the transition is designed without using any vias. Simulation and measurement results for a back-to-back CPW-to-microstrip...
