“…Dual-band power dividers can also be achieved using T-sections [23] and Pi structures [24][25][26] by connecting open or short stubs to the conventional transmission line, but the main drawback of using such techniques is their large physical size. Another modification technique could be presented to provide dual-band power dividers using artificial planar transmission lines [27][28][29], which need a very high resolution facility in fabrication.…”

Abstract-This paper presents a novel quad-band power divider with equal power division ratio. The proposed power divider is realized using two cascaded sections of dual-band transformers based on coupled microstrip lines. Limitations of using dual-band quarterwavelength transformers based on coupled lines are studied through parametric analysis to obtain useful design guidelines related to available fabrication facilities. General closed-form expressions are deduced to calculate design parameters. To verify analysis and design methodologies, a prototype of quad-band equal power divider is proposed. Compared to conventional quad-band power dividers using sections of transmission line transformers, the proposed power divider records a size reduction of about 20% and reduced parasitic effects at higher frequencies according to the usage of only two resistors instead of four with much smaller ohmic values. In addition, a quad-band power divider is proposed, fabricated and measured for 3G and 4G applications at 2.1, 2.5, 3.5, and 3.8 GHz frequencies. Measured and simulated data are in very good agreement which validates the novel design.

“…An improved variation is present in [23], which employed a coupled-line section at the output and eliminated the need of the input port extension. Artificial transmission lines were also used to realize dual-band operation [24]. But all of the above dual-band power dividers [13][14][15][16][17][18][19][20][21][22][23][24] were all equal power dividing structures.…”

“…It is crucial to design dual-band power dividers for practical applications. In the past, several approaches were proposed for the design of dualband power divider [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. In [13], a power divider using two-section transmission lines cascaded was introduced with the main drawback of poor isolation and output return loss.…”

Abstract-This paper presents an approach to the design of a novel dual-band power divider with variable power dividing ratio. To achieve dual-band operation, a novel dual-band quarter-wave length transformer based on coupled-lines is proposed, which is used to replace the quarter-wave length transformer in Wilkinson power divider. The proposed dual-band power divider features a simple compact planar structure with wide bandwidth performance for small frequency ratio. Closed-form design equations with one degree of design freedom are derived using even-and odd-mode analysis and transmission line theory. For verification purpose, power dividers operating at 2.4/3.8 GHz with dividing ratios of 2 : 1 and 1 : 1 are designed, simulated and measured. The simulated and measured results are in good agreement.

Abstract-In this paper, different topologies of dual-frequency modified 3-way Bagley polygon power dividers are designed and analyzed. Equal split power division is achieved at arbitrary design frequencies. In the first structure, two-section transmission line transformer is used to realize the dual-frequency operation. In the second and third structures, dual-frequency T-shaped and π-shaped matching networks are used. For the sake of simplicity, closed form design equations are presented for each matching network. To validate the design procedure, three examples are designed, simulated, and fabricated. The three matching networks are explored through these three examples. The design frequencies are chosen to be 0.5 GHz and 1 GHz.
