摘要
Techniques for multiband radio frequency (RF) signal communications using integrated multiple-input multiple-output (MIMO) multiband bandpass filter bank based on concentric dielectric ring resonators are described. The integrated MIMO multiband bandpass filter bank includes a plurality of transmission line structures for transmitting and receiving radio frequency (RF) signals, and a plurality of ring resonators with different sizes and different resonant frequencies electromagnetically coupled to the plurality of transmission line structures, wherein each ring resonator of the plurality of concentric ring resonators is configured as a single-band bandpass filter to allow a bandpass signal to pass through. By the use of integrated MIMO multiband bandpass filter bank, multiple desired bandpass signals corresponding to the multiple resonant frequencies of the multiple dielectric ring resonators can operate to transmit and receive in the processing of multiband RF signals while having out-of-band spurious emission and interference rejection.
