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.
Microstrip Manufacturing Methodology. Typical approaches to manufacturing microstrip circuits start with a commercial circuit laminate with metallized top and bottom layers using a highly conductive metal, such as copper. The top layer is etched to remove unwanted metal, leaving the traces that form the microstrip circuitry and transmission lines.

Use the microstripLine object to create a microstrip transmission line. A microstrip line is a transmission line that is a basic building block for most RF planar microwave devices. You can use this transmission line to connect two PCB components or to create components such as filters, couplers, and feeding elements of various types of antennas.
What is a Microstrip? A Microstrip is a type of transmission line in which a strip of a conducting material like copper is mounted on a dielectric material and routed to a ground plane. The width of the conducting layer is important to calculate the radiation intensity since it directly affects the bandwidth of the signal waves.
