The ring down of the antennas is a huge bottleneck in spectroscopic measurements involving relaxation time (T2) measurements. The ring down of the antenna determines the dead time of the spectrometer.
The only way to determine the characteristics of an antenna is to measure its performance since theory alone cannot predict the actual results. The fields generated by antennas are extremely complex ...
The purpose of this article is to explain, in detail, the process involved in building and tuning a high-frequency (HF) RFID antenna, which would operate at 13.56 MHz. Some concepts will be explained ...
