This series of articles reviews UHF transmission line antennas developed for RFID Printer-Encoders. It explains the basic operating principles of antennas, their effect on the printer’s encoding function as well as how the antennas influence the design of labels with embedded transponders (Smart Labels). The survey of antennas is preceded by the evaluation of antenna-transponder mutual coupling...

For the last 18 months the author has been involved with Pixel Technologies in developing and producing the high-gain low-noise preamp used with the company’s series of shielded magnetic loop antennas. Recently Pixel asked me to perform a series of comparative tests on the latest version of their loop antenna (Model RF PRO-1B) to determine how it performs relative to other loop antennas and oth...

SOORA, SHRUTHI. A Comparison of Two and Three Dimensional Wire Antennas for Biomedical Applications. (Under the direction of Prof. Gianluca Lazzi.) Miniature antennas are necessary to reduce the size of communications and biomedical devices, specifically for a retinal prosthesis. A comparison of two dimensional and three dimensional antennas are presented as an attempt to miniaturize and reduce...
