Abstract [en]

A novel compact dual-band power divider with filtering responses is presented in this article. The proposed circuit utilizes coupled quarter-wavelength stepped-impedance resonators. By controlling these resonators, dual-band operation can be realized. Furthermore, a resistor is connected between the two open ends of the input feed line to obtain good isolation at two bands. Source load coupling is utilized to enhance the selectivity. To verify the proposed idea, a filtering power divider with the operating frequencies of 2.4 and 5.8 GHz is implemented. Good agreement between the simulated and measured results validates the proposed idea. The total size of the circuit is 0.23(g) x 0.28(g), where (g) is the guide wavelength of 2.4 GHz.
