“…By utilizing the double‐side parallel‐strip line and mid‐inserted conductor plane, the frequency ratio of 2.44 to 7.31 can be achieved . With the help of coupled‐lines and open stubs, the range of frequency ratio could be from 1 to 7. In Reference , a multiband power divider is proposed based on a multisection stepped‐impedance transformer, where the dual‐band case has a maximum frequency ratio of 7.75.…”

In this article, a dual‐band Gysel power divider is proposed based on the topology of finite‐ground microstrip line. The general design method for the large frequency ratio and unequal power division is derived and the detailed design rules are provided. It is shown that the frequency ratio can be achieved from 1 to 10, and the power division ratio of each frequency band can be separately determined. Moreover, the phase differences at two operating bands could be designed to be either in‐phase or out‐of‐phase. Finally, two prototypes are designed, implemented, and experimented to validate this proposal. The measured results of the first design show the frequency ratio of 4 with power division ratios of 2:1 in both passband, while the second example is designed with the frequency ratio of 10 with power division ratios of 2:1 and 1:1 in the first and second passband, respectively. Both results show a good agreement between the simulated and measured results.

“…Nowadays, the rapid increase of wireless communication leads to a great demand in designing multiband components. [4][5][6] Many dual-band (DB) WPDs have been presented with only resistors, [7][8][9][10][11] open/short-ended stubs, 12,13 or lumped elements. [14][15][16][17][18][19][20] The WPD topology consisted of two-section transmission lines (TLs) and resistors are proposed in References 7-9, which has limited frequency ratio range (from 1 to 3) due to using equal physical lengths of TLs.…”

A dual‐band (DB) Wilkinson power divider with multiple design approach is proposed in this article, which consists of two‐section transmission lines (TLs) with arbitrary length ratio, one parallel LC circuit, and one resistor. Compared with the former works with equal physical lengths, the total physical size of the two‐section TLs can be decreased effectively. For a given DB frequency ratio, the maximum size reduction can be newly summarized as (n‐1)/(2n), where n indicates the length ratio of two‐section TLs. From the close‐formed design equations, multiple solutions of circuit parameters are newly summarized for DB operation, thus circuit design could be much more flexible and more efficient. Furthermore, in order to compact the proposed circuit size, compensation technology for two coupled‐line sections is also considered in circuit fabrication. Finally, design charts and an experimental circuit show good agreement with the theoretical simulation. Compared with the former work under the same design conditions: f2/f1 = 3.2, f1 = 1 GHz and f2 = 3.2 GHz, the proposed work provides compact circuit size and the size reduction is 25% with n = 2, m = 1.

“…To now, studies on the power division networks, especially for the three-port ones, are extensive. These studies are primarily focused on size reduction [2][3][4], dualor multi-band incorporating with multi-function like filtering [5][6][7][8][9], etc. To feed an antenna array, dedicated RF power applied to each antenna element is necessary in practice, thus making the unequal power division to be of important.…”

A four-way network with 45 deg output phase shifts for feeding antenna array is studied in this work. To widen the phase imbalance, quarter wavelength short stubs with suitable characteristic impedances are introduced and numerically analyzed. Meanwhile, the wideband magnitude imbalance is also discussed by extending the inter-stage transmission line with proper electric length. The study is further confirmed by developing a prototype feeding network centered at 3 GHz. Results from the fabricated prototype network exhibit wideband good performance, both from numerical evaluations and experimental demonstrations.
