摘要
In this letter, a new compact two-pole band-pass filter (BPF) based on an asymmetric short-circuited spurline resonator is presented. The filter is modeled by means of a new multimodal circuit model for a microstrip to three-line-microstrip cross, which allows a rigorous study of a very generic new family of filters. A BPF centered at 1.9 GHz has been designed, measured, and simulated using this multimodal model. A good agreement between measurements and simulations has been obtained.
