“…The dimensions of our design have diminished by 10% compared to the WPD reported in [14]. But more importantly, the conditions for the isolation and return-loss of the proposed WPD are better than the PD in reference [14]. It can also be argued, for example, that the proposed WPD, compared to the structure introduced in reference [21], is only slightly smaller in size, but the conditions for isolation and insertion-loss are more appropriate.…”

A novel Wilkinson power divider is presented in this paper for triple band operation. It comprises a П-shaped transmission-line coupled to a rectangular split ring resonator metamaterial structure. The μ-negative feature of the rectangular split ring resonator metamaterial structure is investigated by retrieving its constitutive parameters from the S-parameter response. To demonstrate the versatility of the proposed Wilkinson power divider it was designed to cover Bluetooth (2.4 GHz), WiMAX (3.5 GHz), and WLAN (5.2 GHz). The tri-band Wilkinson power divider was fabricated and its performance measured to verify the design. Good agreement between the measured and simulated data is obtained. Measured results show that the tri-band Wilkinson power divider has fractional bandwidth of 3.86%, 5.82%, and 3.89% at 2.4, 3.5, and 5.2 GHz, respectively. In addition, the rectangular split ring resonator metamaterial Wilkinson power divider has a small physical footprint (14 mm ×17.9 mm or 0.15λg×0.19λg), which is 60% smaller than conventional designs.

“…The modern wireless communication systems are more focused on multiband radio frequency components. [2][3][4][5][6][7][8][9][10][11][12] Till now a lot of dualband Wilkinson power dividers have been developed, but a very few tri-band power dividers are proposed. For example, some tri-band power dividers are implemented based on the three section transmission lines, 2,12 coupled lines, 10 resonators.…”

“…5,9,11 The resonators were designed using lumped elements 11 like inductors and capacitors and also with open and short stubs. 5,9 The tri-band Wilkinson power divider were also achieved by replacing the quarter wave length lines in traditional Wilkinson power divider with M-shaped inverters, 7 quarter wave open circuited stubs, 8 composite right and left transmission line. 3 A new design methodology to design a triband Wilkinson power divider based on admittance approach is proposed by Chu et al 4 But in some designs, more than one SMD resistors were used 3,11,12 or SMD inductors and SMD capacitors were used, 11,12 which may increase the cost.…”

In this article, an equal split triple‐band Wilkinson power divider is reported. The triple‐frequency operation is obtained by employing an extended cross‐shaped microstrip line. This proposed geometry is constructed using a cross‐shaped structure attached with two series microstrip lines at two ports. The circuit parameters are computed from the graphical solutions plotted based on the derived formulas. To validate the synthesis approach, a triple‐band power divider intended to operate at 0.9/3.15/5.4 GHz is developed, fabricated and tested. A good consistency is observed on the tested and simulated performances. The measured isolation and return loss are greater than 28 dB at all the operating frequencies. The prototype provides a good insertion loss of 3 ± 0.3 dB at the center of each frequency band. Considering minimum 15 dB return loss and maximum 0.5 dB amplitude imbalance, the bandwidths at 0.9, 3.15, and 5.4 GHz are obtained as 140, 130, and 110 MHz, respectively.

In this work, the design of miniaturized dual‐ and triple‐ frequency Wilkinson power dividers using nonuniform coplanar waveguides is presented. The miniaturized configurations are achieved by replacing the conventional uniform arms with their equivalent multi‐frequency nonuniform transmission lines. The nonuniform width variation is governed by a truncated Fourier series expansion with coefficients optimized to obtain the desired multi‐frequency operation. The optimization process is carried out through the analysis of the even/odd mode circuits. The proposed dividers are simulated, fabricated, and measured to validate the design methodology. Simulated and measured results agree very well, and show input/output ports return loss and isolation better than 14.4 dB and transmission parameters in the range of −3 ± 2 dB at the design frequencies. Size reduction of 16.7% and 17.6% are achieved for the fabricated dual‐ and triple‐frequency dividers, respectively.
