- Abstract
In this paper a very compact design of a dualband band pass filter (D-BPF) using dual composite right- /left-handed (D-CRLH) and open-loop ring (OLR) resonators is presented. To overcome the frequency ratio limitations of D-CLRH resonators technique, the D-BPF design combines D-CRLH and OLR resonators to finally perform a D-BPF. The filter covers the 2.6 and 3.5 GHz spectrums for 4G and 5G applications, respectively. The reported D-BPF is designed and optimized using ADS software, and is implemented on a Rogers RO5880 substrate with a relative dielectric constant of 2.2 and thickness of 0.787 mm. The overall compact size is 8 × 8 × 0.787 mm³ . To our knowledge, this design is considered as the most compact and smallest size dual-bandpass filters.
