A generic microstrip structure is used for the design of all-type broadband filters, based on the analogy between wave and transmission line theories. A Matlab-based lumped (LC) and scattered (microstrip line) filter design tool is developed for the automation of the filter design. Sample lowpass, highpass, bandpass, and bandstop filters are designed and their operational characteristics are validated via in-house prepared FDTD-based virtual microstrip circuit simulator.
