“…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.…”

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 paper, an -plane waveguide power divider and a waveguide-to-microstrip transition are used to form a waveguide magic-T with four arms in the same -plane. The input port of the original -plane waveguide power divider acts as the difference port of the magic-T, and a waveguide-to-microstrip transition is utilized to realize the sum port. The four arms are in the same plane, and traditional matching elements, such as cones, wedges, pins, and irises are not needed. The proposed magic-T features easy connection, fabrication, and assembly. The principle and design procedure are described in detail. A -band -plane waveguide magic-T is designed, fabricated, and measured. A fractional bandwidth of 21% is achieved. The measured and simulated results show good amplitude, phase, and isolation characteristics validating the proposed magic-T.

Abstract-In this paper, a new dual band balanced-to-balanced power divider is proposed. By using the dual frequency 90 • phase shifter based T model, the proposed balanced-to-balanced power divider can be deduced. By using the method in our previous work, the dual band balanced-to-balanced power divider could be designed with 1 : 1 power division. This balanced-to-balanced power divider is implemented on microstrip structure. Comparing the results calculated in analytical method with that simulated by the full-wave electromagnetic simulator, and that measured by the network analyzer, the final results show that they have a good mixed mode performance. The pass band 1 is from 2.395 GHz to 2.550 GHz, and the pass band 2 is from 5.245 GHz to 5.30 GHz. The maximum isolations for pass band 1 and pass band 2 are 17.8 dB and 17.6 dB, respectively.
