“…As the Chebyshev matched WPD circuit is symmetrical, the reflections seen at the second and third ports are equal ( S 22 = S 33 ). The same situation is also observed in the transmission and isolation parameters ( S 21 = S 31 and S 23 = S 32 ) . Figures and show the S parameters in the input and output ports.…”

In this study, an ultra-wide band (UWB) energy harvesting circuit was proposed using the Greinacher rectifier circuit. The circuit was designed with Wilkinson power combiner (WPC) for use at two different radio frequency signal inputs. To enable broadband operation, the multisection Chebyshev impedance matching technique was applied in the branches of the WPC circuit. The center frequency was selected 2.2 GHz in the design. In terms of the parameters of reflection, transmission and isolation, the WPC circuit operates in the 0.4 GHz-3.4 GHz range and the percentage bandwidth has been calculated as 136%. In the designed Greinacher rectifier circuit, power conversion efficiency (PCE) was analyzed for different input powers. When load resistor selected as R = 1500 Ω, the PCE for the input power of 9 dBm was about 70%. The proposed circuit, where WPC and Greinacher rectifier circuits was used together for energy harvesting; was operated in the frequency ranges BW 1 = 0.4-0.81 GHz, BW 2 = 1.54-1.84 GHz, and BW 3 = 2.2 GHz-2.89 GHz. As a power combining application, dual power inputs were applied to the WPC circuit with frequencies of Eventually, approximately 70.5% PCE and 1.65 V output voltage were obtained.

“…The SIW power divider becomes a key component at millimeter wave band and widely used in array antennas, multiplexers and power amplifiers (PAs). In recent years, the development of SIW power dividers with low insertion loss, broadband, miniaturization has been attracted many researchers [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. A high isolation SIW power divider based on the fixed width lines has been designed [8].…”

In this paper, a novel design of highly compact power divider employing substrate-integrated waveguide (SIW) is proposed for dual-band applications. The double-ring asymmetric complimentary split-ring resonators (CSRRs) are utilized to obtain dual-band operation. The asymmetric double-ring CSRRs create mixed magnetic and electric coupling resulting two distinct resonating frequencies which exhibits bandpass behaviour below the resonating frequency of the cavity. The resonating passbands can be designed individually by varying the dimensions of the proposed CSRRs. In addition, the position of output ports can be varied to achieve arbitrary power division. To demonstrate the proposed analysis, three prototypes (two equal power division and one unequal power division) of dual-band SIW power dividers are designed and fabricated. Measurement performance provides a good consistency with that of simulated one. The circuit areas of the fabricated prototypes 1, 2 and 3 excluding microstrip transitions are 0.053λ g 2 , 0.088λ g 2 and 0.033λ g 2 , respectively. The proposed design process exhibits dual-band performance with smaller circuitarea, suitable isolation and hence appropriate for dual-band communication services.

Lately, it has been seen that wireless communication systems have been more developed and there has been a huge demand for multi-spectral transactions. Using circuits for more than one function is a serious requirement in communication technology. Especially, it expected from RF output stages to show the same performance on more than one frequency. To that end, it is required to produce a solution with wideband designs. In this study, a novel power divider/combiner design with a layered conic line has been investigated for the RF energy harvesting applications. The center frequency was set at 2 GHz and concluded with three different designs. In each design, bandwidth and S parameter characteristics were compared according to the number of layers of the transmission, and it was observed that as the number of layers increases, the bandwidth also increases. According to the design result, triple layer Wilkinson power divider was selected to connect to Villard voltage doubler circuit. The Wilkinson power combiner circuit inputs were given between −10 dBm and 5 dBm input power. As a result, when low input power was given, efficiency was observed about 70%.
