“…The SIW FPD in Reference 19 achieves the four‐way outputs by adding four coupled lines for the outputs with equal power division ratio, which is not suitable for the application in the antenna array with zero sidelobe, as in Figure 1. In Reference 26, a multi‐layer SIW three‐way FPD realizes unequal power division ratio by adjusting the length of the microstrip line to control the coupling energy, but low division ratio (1:1:1.5) is developed. In the proposed design, the desired division ratio is obtained by flexibly controlling Q e of each output port.…”

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.

“…The effect of air gap between the two substrates also lead to some magnitude and phase errors. The comparisons of the fabricated power dividers with some previously reported SIW power dividers 11–14 are shown in Table 2. The proposed power dividers have advantages of wide bandwidth, small magnitude imbalances and low phase differences.…”

“…At present, power dividers with in‐phase and out‐of‐phase responses are widely used in RF microwave circuits, including balanced mixers, push‐pull amplifiers, and antennas 1–2 . A variety of power divider architectures have been reported to obtain the in‐phase and out‐of‐phase feature, such as hybrid couplers, 3–4 filtering balanced power dividers with wideband common mode suppression, 5–8 tunable power dividers, 9–10 SIW, and substrate integrated suspended line (SISL) power dividers 11–17 . Among them, 180° hybrid couplers 3 are.…”

“…SIW circuits have advantages of low cost, high Q , and easy integration process for the planar circuits. Some high‐performance SIW power dividers are reported 11–14 . In former works, SIW out‐of‐phase power divider is realized by the coupling way between the top and bottom SIW walls, 11 and the output ports are in different layers, which are difficult to connect in practical application.…”

“…In former works, SIW out‐of‐phase power divider is realized by the coupling way between the top and bottom SIW walls, 11 and the output ports are in different layers, which are difficult to connect in practical application. The SIW power dividers bandwidth in 12–14 are less than 40%, and the coupling parameters are difficult to obtain due to lack of accurate equivalent circuits.…”

In this paper, two wideband multi‐layer substrate integrated waveguide (SIW) power dividers are proposed. Transitions based on microstrip‐slotline‐SIW coupling for TE40 mode SIW cavities are used to realize the out‐of‐phase and in‐phase difference. The equivalent circuits are used to show the basic design guidelines and impedance matching for the two power dividers. To validate the design, two prototypes over 62.5% fractional bandwidth at 8.5 GHz center frequency are designed, good results can be found between the measurement and simulation results.

In the paper, a high‐selectivity wideband four‐way filtering power divider with input absorptive feature is presented. It consists of two parallel‐coupled lines (CLs), two three‐coupled lines (TCLs), two open‐ended stepped branches, one absorptive branch, and two isolation resistors. The wideband filtering response is achieved by cascading the TCLs and CLs. While high selectivity is obtained by loading the open‐ended stepped branch, where two extra transmission zeros are generated. In addition, wide absorptive bandwidth with good isolations between adjacent output ports are realized by combining the absorptive branch with the isolation resistors. Equations are derived by using the two‐parity mode analysis, and main parameters are investigated in detail. For validation, a prototype was designed and fabricated. Test results show that the 3‐dB FBW can reach 87% with a 10‐dB input absorptive FBW of 200%. Besides, for the output ports with 10‐dB return loss and 10‐dB isolation, the FBWs are 94% and 91.5%, respectively. It also features high frequency selectivity and low insertion loss.
