A Novel Dual-Band Unequal Filtering Power Divider

Progress In Electromagnetics Research Letters, Vol. 108, 123-130, 2023
Abstract
In this paper, an unequal Filtering Power Divider (FPD) adopting a novel dual-band resonator and inter-digital feeding lines structure is presented. By integrating the resonator and modifying coupling mode, filtering and unequal power distribution are all achieved on the base of the deformed Wilkinson power divider. Two sets of cascading resonators operating at 2.45/4.44G with the same structure are proposed for WIFI and other application. Keeping with the unchanged coupling mode, the unequal ratio of 2:1 is arrived by adjusting the strength of coupling. The two resonant frequencies can be adjusted independently to ensure the flexibility of the design. For verifying the theoretical designs and simulated results, a fabricated FPD is exhibited, analyzed and measured. The simulated results are in good agreement with the measured ones with slight variations.
