摘要
Abstract
A low-profile,compact dual-band rectifier circuit is proposed,which can be used in scenarios such as radio frequency energy harvesting and microwave power transmission.The proposed rectifier circuit does not employ an impedance matching network,and achieves dual-band characteristics using only two microstrip transmission lines:the first microstrip transmission line connects the Schottky diode(HSMS-2850)with the load and filter at the rear end of the rectifier circuit;the second microstrip transmission line is a half-wavelength microstrip transmission line,adding a second frequency band to the designed rectifier circuit.This design approach not only reduces the overall size of the rectifier circuit(0.14λ0×0.11λ0,where λ0 is the wavelength corresponding to the lowest frequency),but also minimizes the losses introduced by additional matching structures.After theoretical analysis,simulation,and fabrication,the measured results of the rectifier circuit are essentially consistent with the simulated results.When the input power is 0 dBm,the operating frequency bands of the rectifier circuit are 1.44～1.66 GHz(14.2%)and 3.35～3.54 GHz(5.5%),with maximum rectification efficiencies achievable within the bands being 73.7%and 69.5%,respectively.关键词
