Abstract
The use of radial stubs in microstrip stepped-impedance resonator bandpass filters is investigated. It is noticed that the stopband rejection level can be enhanced with minor deterioration in the filter´s passband characteristics. Demonstration filters were fabricated with the measured and simulated results presented.
