Abstract-This paper proposes a 10 : 1 unequal Gysel power divider using a capacitive loaded transmission line (CLTL). For obtaining a high dividing ratio of divider, the CLTL is proposed to realize a low characteristic impedance line below 10 Ω. A design method using a CLTL which consists of a small transmission line with shunt open stub at periodic intervals is newly suggested for power divider with the high power division ratio. For the validation of the CLTL power divider, the high dividing ratio of the fabricated Gysel divider is measured at a center frequency of 1 GHz. The measured performances are in good agreements with simulation results.

“…The comparisons of the proposed divider with other published Gysel power dividers are summarized in Table 1. The size consideration (λ/6 × λ/3) in this work and the size comparison with references [18][19][20] summarized in Table 1 are measured by the electrical length of the power divider instead of the whole substrate area. It can be seen that based on the patch type structure, both bandwidth enhancement and size reduction are obtained without complex design and optimization procedures.…”

“…The Gysel power divider is devised with several advantages such as high power-handling capability and monitoring capability for imbalance at the output ports [18], in which aspects it outperforms the Wilkinson power divider. However, the conventional Gysel power divider has two disadvantages that limit its application.…”

Abstract-A novel Gysel power divider based on patch type structure is presented in this paper. The proposed power divider possesses broad bandwidth, small physical occupation and arbitrary power division. More than 30% bandwidth enhancement is achieved based on the −15 dB input return loss criteria, while 55% size reduction is realized compared with conventional Gysel power divider. What's more, flat dividing is obtained in the design without using additional transmission line sections. Based on the novel structure, a design procedure of power dividers with unequal power division ratios is provided without using narrow microstrip line. To verify the design approach, the proposed power dividers with equal and unequal (2:1 and 4:1) power divisions at the centre frequency 1.5 GHz are fabricated and measured. The results demonstrate that the design can fulfil our goals.

Abstract-In this paper, Gysel type Unbalanced-to-Balanced (UTB) Power Divider (PD) with arbitrary power division is proposed. UTB PD is a five-port device, and a standard scattering matrix for a five-port PD with arbitrary power division is derived. Design equations are obtained analytically. Using design equations, a UTB PD is designed at 2 GHz for power division ratio of 1 : 2, and simulation is carried out using HFSS. A prototype is fabricated, and measurement is performed to verify the simulation results of PD. Measured results are in good agreement with the simulated ones. The proposed PD shows in-phase characteristic within ±5 • . Measurement results show that isolation between two output ports is greater than 20 dB. Greater than 20 dB common-mode suppression from input port to output balanced ports is achieved. Differential-mode power is divided in power division ratio of 1 : 2 from unbalanced port to balanced ports. Measured fractional bandwidth of the proposed PD is 21%.
