“…Also, an unequal UWB power divider analysis based on the idea of two section transmission line is proposed. On contrary to the unequal power dividers presented in [11] [12] [13], the proposed design is simple and efficient because it can be viewed as two section quarter wave transformer. open stubs lengths can shift the suppressed harmonics outside the UWB range [14].…”

In this paper, two ultra-wide band power dividers are introduced. Compact equal power divider is considered firstly where an extended transmission lines and double open stubs are used in order to increase the bandwidth. Secondly, an unequal UWB power divider is introduced where multi-stage impedance is used. The proposed power dividers are fabricated and measured. The overall sizes of the proposed power dividers are 11.37 × 17.87 mm 2 for the equal one and 12.13 × 29.03 mm 2 for the unequal power divider. The simulated results are compared with the measured results and good agreement is obtained.

“…However, unequal power dividers are needed in antenna array feed networks. One Wilkinson power divider for unequal ratio based on shunt stubs and uniform characteristic impedance structure was proposed in [5]. Unfortunately, the fractional bandwidth is small and the size is relatively large.…”

A compact ultra-wideband (UWB) power divider with unequal distribution ratio is proposed in this paper. The UWB power divider is based on the conventional unequal Wilkinson power divider with two folded shunt quarter-wavelength short-circuited stubs separated by quarter-wavelength connecting lines at each output ports. The unequal distribution ratio is achieved by adjusting impedance ratio of two output ports. In addition, a single resistor is properly placed between two output ports for improving isolation. Finally, the simulated results are presented, which are in good agreement with the measured ones. Keywords-Power divider, ultra-wideband (UWB), unequal distribution ratioI.

An effective method is introduced to overcome the narrow strip width in unequal Wilkinson power divider with high dividing ratio. In the proposed method, the separated microstrip lines of the Wilkinson power divider are replaced by a uniform asymmetrical microstrip coupled lines. It is shown that in the proposed method, the width of the narrow microstrip line is significantly wider in comparison to the narrow microstrip line in the conventional Wilkinson power divider with the same specification. To design the power divider, a suitable error function is defined and then minimized which led to the final dimensions of the power divider. A sample of the designed power divider with 4 : 1 dividing ratio is fabricated and tested, which indicate the effectiveness of the proposed method.
