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