摘要：Multi-band radio frequency communication is performed using an integrated
multi-band bandpass filter implemented based on ring resonators, such as concentricdielectric ring resonators. By constructing the multi-band bandpass filter using concentricring configurations, the print circuit board (PCB) real estate requirement of multiplefilters operating at multiple frequency bands is significantly reduced. Various
configurations of the multi-band bandpass filter based on the concentric ring resonatorsprovide flexibility in the layout design and manufacturing of multi-band radios for mobiledevices, such as compact smartphones. These configurations of the concentric ringresonators can include but are not limited: a slot-coupling configuration, a direct-coupling configuration, and an embedded direct-coupling configuration.
