A new planar slotted‐patch resonator is proposed for RF and microwave bandpass filter design. The novelty of the proposed resonator is that it can reduce the size of the filter significantly. It is found that the resonant frequency of the resonator is reduced (for example, by 61%). A dual‐mode filter operating at 2.39 GHz with 1.7% bandwidth and a three‐pole bandpass filter operating at 2.375 GHz with 8.8% bandwidth are designed and fabricated. The measured results agree very well with the full‐wave EM simulation. © 2006 Wiley Periodicals, Inc.
