RFID TAg Antenna Application Series
RFID system performance hinges, in large part, on tag performance. And the tag, in turn, relies on a handful of elements that determine its performance—the antenna being an especially critical one. This series of technical briefs considers the essential qualities of tag antennas. For more antenna information, also see the reader antenna application notes.
This installment considers the tag antenna in the context of the larger RFID system. Read more...
There is no single best antenna design for every application operating in every region of the world, which is why there has been such a proliferation of specially optimized forms and configurations. Read more...
Maximizing a tag's ability to transfer energy efficiently is key to increasing the range and robustness of an RFID system. Read more...
Effective tag read range is a function of many variables. Some of these variables are a function of the nature of UHF, while others depend on the design of the system elements, including the tag antenna. Read more...
Antenna design comes down to two fundamental forms: the half-wave dipole and the full-wave loop. Combining the loop's sensitivity, orientation, and radiation patterns with that of the complementary dipole form will yield more robust tag performance in a number of potential applications. Read more...
The use of conductive ink, specially formulated for the printing of antenna geometries onto an inlay substrate, is one keys to yielding low-cost, high-performing tags. Read more...
The dielectric impact contributed by various materials in close proximity to (or in contact with) the tag—known as loading—may detune a tag antenna, leading to energy loss, and ultimately, reduced range. Read more...
When a pallet stacked with RFID-tagged cartons travels through a dock door's read zone, the resulting read rate is a function of a number of variables, one of them being tag placement for tags that use a dipole-type antenna. Read more...
