Abstract :
A recent method of analysis that takes into account fringe effects is applied to 2-port annular structures. It is shown that the filtering properties of the structure can be controlled by varying the ring width and/or the position of the ports. Experiments performed on microstrips are in good agreement with the theoretical results.
