“…It is advantage over earlier power dividers with high division ratios is simplicity of design and fabrication used DGS on the ground planes and are not compatible with the single layered fabrication, which complicates design and fabrication. used periodic shunt capacitive loading, which both complicates the design and fabrication, and increases the size of the circuit. The proposed structure reduced the size of about 30%.…”

This article introduces a modified Gysel power divider, providing high power division ratios, alongside the advantage of high power handling. To overcome fabrication limitations of high characteristic impedance line, caused by the anticipated high power division ratio, a coupled line structure with two shorts is used. This proposed structure makes closed‐form equations available for design and leads to a simple microstrip fabrication. A 10:1 unequal Gysel power divider is presented and fabricated as a design example and a satisfactory agreement between measurements and simulation results is verified. © 2016 Wiley Periodicals, Inc.

“…To overcome this shortcoming, some new types of unequal Wilkinson PDs with high power division ratio were proposed. The methods are mainly summarized as follows: the microstrip line with Defected Ground Structure (DGS) patterns [4][5][6][7][8], double-sided parallel-strip lines (DSPSL) [9][10][11], composite right left-handed transmission lines (CRLH-TLs) [12][13][14], a two-port filtering structure connected to a circulator [15,16] and other methods [17][18][19].…”

“…[15,16] provided a novel type of power divider, featuring arbitrary power ratio and arbitrary ripple level. Other methods [17][18][19], such as using shunt stubs [17], using coupled lines with two shorts [18], using a microstrip line with a periodic shunt open stub to achieve low-impedance lines [19], were also adopted to design unequal PD with high power-dividing ratio.…”

A simple and analytical design methodology for a novel planar four-port structure to implement power divider (PD) or balun with variable power division is proposed in this paper. It consists of two different 3 dB branch-line couplers and one coupled-line phase shifter whose length can be changed to implement variable power division. Different from the previous designs, the power divider and balun with variable power division can be realized in only one circuit by changing the electrical length θ 0 of the coupled line when the impedance ratio g is selected. According to the ABCD parameters and linear algebra calculation, closed-form mathematical equations for the circuit electrical values and scattering parameters can be obtained. A prototype with this proposed circuit, operating at 2 GHz, has been designed and fabricated using microstrip technology. Good agreements between the calculated and measured results verify our design.

In this paper, we propose the design and performance of an unequal divider using transmission line with periodic capacitor shunt connection. To design divider with a high dividing ratio, we limit a high impedance line value to fabricate microstrip line and also, design a low impedance line of below 10 Ω using periodic capacitor shunt connection. As a design example, a 10:1 ratio divider was designed and measured at center frequency 1 GHz to show the validity of the unequal divider using periodic capacitor shunt connection. Its performance is in good agreements with the simulated results.
