The impedance matching in the circuit is only realized by two-stage microstrip lines, which reduces the physical size of the rectifier and makes the rectifier more compact. Judging the measurement results from 0.8 to 2.5 GHz, the conversion efficiency is greater than 30% at 0 dBm, the bandwidth is 103%, and the maximum conversion efficiency ...
Microstrip lines transfer power from one point to another, divide or combine power signals, and generate phase shifts. Half-wave and quarter-wave microstrip lines are used to design lumped elements. Microstrip lines are a type of transmission line commonly used in RF and microwave circuits due to their quasi-TEM mode of propagation and flexibility.
The electromagnetic wave carried by a microstrip line exists partly in the dielectric substrate, and partly in the air above it. In general, the dielectric constant of the substrate will be different (and greater) than that of the air, so that the wave is travelling in an inhomogeneous medium. In consequence, the propagation velocity is somewhere between the speed of radio waves in the ...

RF structures can be complicated to design and layout, particularly because many RF systems lead double lives as digital systems. Getting an analog signal out of a component and into a waveguide for high isolation routing is not so simple as placing a microstrip or stripline coming off your source component. Instead, you need to create a …

Integrating the stretchable microstrip antenna with a rectifying circuit that has an embedded matching network conveniently yields a rectenna to harvest RF energies (Fig. 6 a and Fig. S13a). The RF source with a power of 7 dBm (5.02 mW) from the evaluation board is used to evaluate the energy harvesting performance of the resulting rectenna.
