Today’s microwave designers rely on many tools to help create effective circuits and systems. They use their libraries of pub-lished references, along with powerful EDA design tools and electro-magnetic (EM) analysis tools, combined with the lessons of their own experience. Their work is verified with the construction and testing of a finished circuit. This article describes two microstrip designs that were developed using different methods, fabricated quickly using a p.c. board milling machine, then measured to determine the accuracy of the design methods.
