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. © 2010 Wiley Periodicals, Inc.
