“…BPDs with uniform TLs have shorter total TLs electrical length than the one obtained using the quarter-wavelength TLs method proposed in [10]. Moreover, microwave components with uniform TLs are easier to fabricate and may have less discontinuities than the components with thick and thin lines.…”

“…The unequal-split BPD appeared for the first time in [10], in which, 3 and 5-way unequal-split BPDs were proposed. The TLs between the adjacent ports in the proposed dividers in [10] have the length of quarter-wavelength at the design frequency. The characteristic impedances of these lines are determined using analytically derived equations to achieve a specific split ratio.…”

In this paper, we systematically derive design equations for 3-way Bagley power dividers with arbitrary split ratios using interconnecting transmission lines with the same characteristic impedance. The exact value of the characteristic impedance for a specific dividing ratio is determined using these equations to achieve perfect input port matching. To validate the design procedure, two microstrip dividers with different split ratios, 1 : 3 : 1 and 1 : 10 : 1, are designed, simulated, fabricated, and measured. The desired split ratios are achieved at the design frequency, 1 GHz. Good agreement between simulated and measured results is obtained.

“…22 Some authors have also found that BPDs can be used for unequal output power splitting where, several techniques were reported in the literature to address this issue for 3-way BPD and 5-way BPD. [23][24][25][26][27] The main objective of this article is to investigate seven-way BPD with an arbitrary output power splitting for the first time. It would be of a special interest to extend the number of BPD output ports according to applications of these dividers in wireless communication systems, antenna feeders, radars, and RF amplifiers.…”

An exact design for seven-way Bagley power divider (7-way BPD) is introduced. The objective of this article is to derive general closed-form expressions for the impedances between adjacent ports for unequal-split 7-way BPD. The values of the impedances control the output power ratio. Full derivation of S-parameters followed by exact impedance equations will be presented. A parametric study in addition to several examples will be given to validate the proposed derivation

“…However, GPDs possess a large circuit area as compared to WPDs, and thus, may not be a suitable option for applications where miniaturized circuitry occupation is a must. The Bagley polygon power divider (BPD), on the other hand, is becoming a new research area [18][19][20][21][22][23][24][25][26][27][28]. The BPD offers structural compactness and excellent input port matching and transmission.…”

“…Miniaturized multiband multiway BPDs utilizing NTLs were proposed in [27]. In [28], a generalized design procedure for an unequal split multiway BPD was elaborated. It is noteworthy to point out that BPDs investigated in [18][19][20][21][22][23][24][25][26][27][28] have an odd number of output ports; whereas a novel BPD with an even number of output ports was introduced in [29].…”

In this article, we propose a new design methodology to broaden the bandwidth of a multiway Bagley power divider (BPD). Single‐frequency matching uniform quarter‐wave‐length microstrip lines in the conventional design are replaced with impedance‐varying transmission lines of broadband matching characteristics. The equivalent transmission line model is used for profiling impedance variations, which are governed by a truncated Fourier series. Such variations are determined by finding the optimum series coefficients that result in a wideband matching nature. The proposed technique leads to flexible spectrum allocation and matching level. Furthermore, the resulting structures are compact and planar. First, analytical results of three 3‐way BPDs of different fractional bandwidths are presented and discussed to validate the proposed approach. Then, two examples of 3‐ and 5‐way BPDs with bandwidths of 4–10 GHz and 5–9 GHz, respectively, are simulated, fabricated, and measured. Simulated and measured results are in a good agreement, with input port matching of below −15 dB and −12.5 dB for the 3‐ and 5‐way dividers, respectively, over the bands of interest. The obtained transmission parameters of the 3‐ and 5‐way dividers are −4.77 ± 1 dB and −7 ± 1 dB, respectively, over the design bands. The proposed wideband dividers find many applications in microwave front‐end circuitry, especially in only‐transmitting antenna subsystems, such as broad‐ and multicast communication links. © 2015 Wiley Periodicals, Inc.
