Passive and semipassive RFID tags do not use a radio transmitter; instead, they use modulation of the reflected power from the tag antenna. Reflection of radio waves from an object has been a subject ...

One key factor when it comes to designing solutions using passive UHF RFID is to understand how exactly the technology works, with its benefits and limitations, and to ensure that products are ...

Antennas are sensitive to their surroundings. Thus, when there’s an antenna on the PCB, the layout for the design should take the requirements of the antenna into account, as this can make a huge ...

The design cycle is a little different when the product is wireless and requires an antenna. Antennas change the design process, because it needs to be located with care, in the best position on the ...
