All currently used filter designs, such as elliptic function, self-equalized, and other common types can be implemented in microstrip using this new concept. The proposed filter structures are ideally ...

The Qucs project is a software tool for designing and simulating these microstrip filters, and after inputting the correct parameters, [SEB] got a nice diagram of what the filter should look like.

The fundamental use of filters in electrical engineering is to shape signal spectrum, which is especially crucial in reducing input signal noise in receivers and spurious emissions in transmitters. It ...
