Abstract :
The design of dual-band microwave filters using capacitively loaded cavities (CLCs) is presented and discussed. Two different structures of the dual-mode resonators based on two CLCs nested one into another and on combination of a CLC with a complimentary split-ring resonator (CSRR) are considered. Advantages and challenges of the both designs are discussed. Design examples of the advanced resonators and filters implemented in the low temperature co-fired ceramics (LTCC) as well as printed circuit board (PCB) technologies are presented.
