The electrical biasing circuit is implemented by square copper patches embedded in SIW resonator cavities.
To build this directional antenna, you will need an N-Female chassis mount connector, four #6x1/4" nuts and bolts, 1 1/4" (32 mm) copper wire, pigtail patch cable, and an empty aluminum can.
By the end of Saar's monthlong working retreat, which concludeded last week, that lumber had come to life, and in place of the artist's materials and a cartful of tools stood a figure of compelling presence: a woman, slightly larger than life-size, carved in wood and clad in patches of copper.
After the carving was complete, she scooped out the figure's belly and began to sheathe the form in small patches of copper that she cut to conform to the body's shape, nailing them down along their edges to create a continuous, quilted skin.
Now it is copper-coloured and patched with snow.
In this study, a conceptual design employs the piezoelectric patch to a copper plate to form a so-called piezoelectric fin applicable for heat dissipation.
Interestingly, the black patches seem to be composed of lead oxide (which, as PbO2 Plattnerite, could also contribute to the blackish colour of the patch), mixed calcium and copper carbonate (Ca0.6Cu0.4CO3) with the excess of copper in form of mixed Cu(OH 2/CuO in a ratio of 3 1.
Patch conductors are usually copper, aluminum, gold, etc.
The proposed transparent antenna׳s characteristics are compared with the copper-based non-transparent U-shaped patch antenna, which is also designed to resonate at 750 GHz.
