Performance characterization of screen printed radio frequency identification antennas with silver nanopaste

Low-Cost Printed Flexible Antenna by Using an Office Printer for Conformal Applications

“…Especially, when the roughness dimensions are comparable to the skin depth of the EM waves at the operating frequency, these losses are prominent [17]. The roughness International Journal of Antennas and Propagation of the printed layer has a direct impact on the AC resistance of the antenna which can be described by the following equations [19]:…”

Direct Transfer Patterning of Electrically Small Antennas onto Three‐Dimensionally Contoured Substrates

“…In addition to the fabrication of electrically small antennas, this process can also be applied to other wireless technologies such as high gain antennas, antenna arrays, radio-frequency identification devices (RFIDs), metamaterials and transformation optics. [14][15][16] To demonstrate the value of this process, we designed, fabricated and measured ESAs of various electrically small sizes that operate over several frequency ranges. We show that the antennas fabricated using this direct transfer patterning process have significantly higher performance and are potentially easier to mass produce than previously reported methods of fabricating electrically small antennas on non-planar surfaces.…”

“…This has potential applications in diverse areas such as high gain antennas, conformal antenna arrays, RFIDs, metamaterials, and transformation optics. [14,16,23] …”

Rheological Behaviors and Their Correlation with Printing Performance of Silver Paste for LTCC Tape

“…This shrinkage can be attributed to the solvent loss. Theoretically, the thickness of metal conductor should be constant regardless of the line width since the same mesh is used (Shin et al, 2009). It could be attributed this result to the fact that the edges of the printed line should have a moderate thickness to result in uniform and continuous line width.…”
