“…In other words, the output branches can be used as input and the input branch can be used as output. Reason of this is that passive microwave circuits have reversible feature . The prerequisite for using this feature is the fact that the isolation parameter is high so that the input powers do not affect each other.…”

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.

A novel filtering Gysel power divider (PD) structure based on coupled lines is presented to realize arbitrary power splitting ratio and filtering response. The proposed filtering PD consists of three parallel‐coupled lines, two short‐circuited stubs, two stepped impedance stubs and two grounded isolation resistors. Two transmission zeros (TZs) are introduced by the stepped impedance stubs, which can greatly improve the passband selectivity and out‐of‐band rejection performances. Theoretically, closed‐form equations for the proposed structure are derived based on even‐odd mode method. For verification, two filtering Gysel PDs with equal and unequal power splitting ratios ( PnormalR=1 normalanormalnnormald PnormalR=2) are designed and experimentally demonstrated in this paper.

In the radar system, detection of objects with high accuracy is needed. Therefore, a low sidelobe antenna is needed to avoid interference from other detected targets. One method to suppress sidelobe antenna is by using unequal power divider with Chebyshev polynomial excitation coefficients. In this paper, we will discuss about the design and fabrication of Chebyshev Wilkinson power divider for 3 dimensional radar application. This research was conducted through 4 stages, namely design, simulation, fabrication and measurement. This power divider is realized in the form of a microstrip using Rogers R0-4003C (lossy) substrate with a thickness of 1,524 mm and a dielectric constant of 3.55. The simulation and measurement results are met the desired specifications, the operating frequency is at 3 GHz with a bandwidth of 200 MHz, the return loss is less than -10 dB, the insertion loss value is in accordance with Chebyshev, the isolation value of the port is less than -10 dB, and the unbalance phase is smaller than 2.5°.
