Abstract
A miniaturized microstrip dual-mode filter with different responses is developed in this letter. A coupling and routing scheme is presented to model the operations of this filter. The new filter reduces the occupied area up to 33% compared with the conventional one at 1.89 GHz. Meanwhile, the proposed circuit enables the second harmonic response to be effectively suppressed. A demonstrator filter is designed and validated with good agreement between the full-wave electromagnetic simulations and measurements.
