i believe there are a lot of people working on resonators here. i'm curious on what would the S parameter of a good resonator be like(suppose the resonator is excited by a single port, thus S11 could be the focus)?
i raised the question because often i have the following situation. We may have a well matched antenna. In the S parameter diagram, we do get an ideal match at a specific frequency, however, the efficiency the simulation tools predict is rather poor. This may be resonable, since a well matched component is not necessarily a good radiator, due to its working mechanism. but how could this happed since the energy supplied from the source goes into the component(S11 is good means small reflection) but cannot radiated toward the free space--from a energy conservation point of view?
i've had this problem in my mind for a long time. could anyone help give a good explanation?
