A novel microstrip lowpass filter based on a T-shaped resonator is proposed in this paper that presents wide stopband and compact size. A method of scaling is applied to and studied on the proposed resonator in order to tune its response parameters. To achieve wide stopband, a suppressing cell is designed and connected in series form to the resonator. The resulting filter is then fabricated and measured. Simulated and measured results of the proposed filter verify its advantages over those presented in the references in terms of stopband-width and physical size.
