“…The co‐design of filter and power divider is highly desired, which can not only reduce the overall circuit size but also eliminate the connection loss. Accordingly, filtering power dividers (FPDs) based on microstrip line, 3‐10 metal waveguide, 11 dielectric resonator (DR), 12,13 and substrate integrated waveguide (SIW) 14‐20 have been extensively studied in the past few years.…”

“…The design method is effective for the design with equal division ratio of the outputs, but it is difficult in the realization of unequal division ratio, especially for the multiple outputs. Recently, a dandelion topology is applied to design multi‐output dielectric resonator (DR) FPD with arbitrary division ratio, showing good performance 13 . However, the three‐dimensional (3‐D) structure is not suitable to integrate with planar circuits.…”

A novel and simple design approach of compact four‐way filtering power divider (FPD) using half‐mode substrate integrated waveguide (HMSIW) cavity is investigated in this letter. The pre‐defined power division ratio of the four outputs is obtained by adjusting the external quality factor (Qe) of each output port, while the total output Qe is equal to the input Qe. The four outputs are loaded to a single HMSIW resonator, achieving a compact size. Meanwhile, both bandpass response and power division can be designed independently. For demonstration, a prototype with pre‐defined power division ratio of 1:3:3:1 is designed, fabricated, and measured. The measured results show that the FPD centered at 4.88 GHz owns a 3‐dB fractional bandwidth (FBW) of 11.3%. The insertion loss of the passband is about 1.4 dB and the return loss is better than 17 dB, meanwhile the phase differences of in‐phase four outputs are all within 5° from 4.61 to 5.16 GHz. Good agreement is observed between the simulated and measured results.

A design approach is presented based on insights into power division among modes for a dual‐band filtering power divider using a single multimode resonator. The relationship between the energy of the input port under different modes and the corresponding external quality factor (Qe) is analysed. Then, the power distribution among the in‐band modes and between output ports can be all expressed by Qe. Therefore, the synthesis of a coupling matrix to achieve independent power distribution in the two bands is simplified. For further verification, a quad‐mode dielectric resonator with independently controllable modes is designed. Based on this, dual‐band filtering power dividers with equal and unequal power split ratios (1:1 in the lower band and 2:1 in the higher band) are simulated and implemented. The simulation and measurement agree, proving the correctness of the approach.

“…For multi-channel applications and circuit miniaturisation, four-way FPDs play a crucial role. To the best of the authors' knowledge, only a few four-way FPDs have been developed and most of them operate with single band [7][8][9][10][11][12][13][14][15][16][17][18]. In [7,16], four-way FPDs are realised based on stubs shunted coupled lines which however exhibit either a narrowband (6%) [7] or relatively poor in-band isolation [16].…”

“…For N order filtering response, existing four-way FPDs always involves 4 × N resonators, which occupy large areas. In [18], four-way FPD based on dielectric resonator has also been demonstrated. While interesting results have been achieved in the above FPD designs, how to build a single-/dual-band four-way FPDs with decent operation performance and reduced number of resonators, but flexible design for multi-way application is still a challenge, especially for dual-band case which is little reported so far.…”

Four‐way single‐/dual‐band operation integrated filtering power divider (FPD) with new design topology is presented in this study. For either single‐ or dual‐passband response, it involves only one same‐type pair of multi‐mode resonators and three isolation resistors, comparing with other existing four‐way FPDs. By adopting the even‐/odd‐mode analysis method to flexibly control the resonant modes of the designed resonator and select isolation resistances, both single‐ and dual‐band four‐way filtering power division responses are specified and derived with the same one configuration. The proposed four‐way FPD designs stand out from the reported ones by both nice operation performance, flexible topology with reduced number of resonators, and no additional feeding network at input port. For demonstration, two prototypes for four‐way single‐ and dual‐band FPDs are implemented following the given design procedure, respectively. Both simulated and measured results are exhibited to verify the theoretical design concept.
