Abstract [en]

It becomes more and more common to print tag antennas using electrically conductive ink for mass-produced Radio Frequency IDentification (RFID) tags. Electrical properties of the ink are mostly determined by conductive (e.g. silver) particles mixed into the ink solution. Since silver is relatively expensive it is desirable to minimize the amount of ink used per antenna. This paper illustrates how the printed conductor area of the antenna can be reduced by applying a grid pattern to an existing antenna geometry and to what extent the gridding can be performed without significantly degrading of the antenna electrical properties. Two common antenna structures are used as an example. It is also shown that by slightly modifying the original antenna geometry it is possible to even further reduce the amount of used ink.

Abstract [en]

Remotely read electronic identification tags are establishing as the standard method of identifying objects in transport logistcs. They are referred to as RFID tags and with successful research and development they are likely to one day replace all of todays barcodes, found on a wide variety of items and objects. As RFID systems consist of many different parts spanning over just as many academic subjects, this thesis investigates some of the main issues regarding RFID tag antennas. Large focus is put on performance and cost optimization of relatively simple one‐layer antennas, suitable for mass production in commercial printing presses using electrically conductive ink. Examples of specially designed antennas include ones that can operate upon metallic objects and antennas that can be physicall bent. It is also shown how RFID tag antennas that will be widely exposed to the human eye can include a commercial value by letting heir geometric design originate from group insignias and company logos. The thesis also presents a solution of how pairs of ordinary low cost RFID tags can be used as remotely read moisture sensors.
