“…It can be seen from the comparison that the proposed work has four arbitrary design frequencies unlike Ref. 28 which only has three. Also, the proposed divider is the first multi-band Gysel power divider to be capable of achieving both equal and unequal power division with satisfactory performance at the four bands.…”

This article presents for the first time a quad‐band Gysel power divider capable of achieving equal and unequal power division at four arbitrary frequencies. The structure of the proposed divider is similar to its single‐band counterpart but loaded with quad‐band reactive networks. The design procedure and theoretical analysis of the proposed divider are presented. A quad‐band Gysel power divider with equal division and another with 2:1 unequal division are designed at the operational frequencies of 0.85, 1.6, 2.4, and 3 GHz. Simulation and measurement results of the two dividers are presented, and good performance is observed at each band. For both designs, the realized power division ratios are within 1 dB from their ideal values, whereas the matching and isolation levels are below −10 dB at the four bands.

This letter presents a novel compact quad‐band power divider using stepped impedance coupled lines. The power divider adopts a stepped impedance coupling line with two transmission zeros as the primary transmission unit and forms a flexible quad‐band in the architecture of the second‐order power divider design through clever impedance matching and transmission zeros design. In addition, the complete and detailed formula derivation and calculation process of this power divider are given, and the specific parameters of the transmission line and coupled line model of the power divider are obtained. Finally, a novel compact power divider operating at 0.9, 1.8, 3.5, and 4.4 GHz is designed and implemented based on the calculation. The test results of the power divider show good performance and are consistent with the simulation results, which proves the effectiveness of the method and structure design.
