Designing
RFID tags using direct antenna matching
Cory Edelman and Murthy Upmaka, Agilent EEsof EDA
In radio frequency identification (RFID) systems, the interaction
between the reader and the tag is of great interest to the system
designer. This paper describes the design challenges involved in
these systems, and focuses on the use of integrated EDA tools to
optimally address these challenges.
UHF
techniques for lumped constant circulators
J Helszajn, Heriot-Watt University
Engineering data is presented for the construction of UHF
circulators. The techniques described are appropriate in the
frequency bands in the range 100 - 1000MHz. Circulator construction
at these frequencies is based on lumped element networks. The
construction of wide band circulators having Chebychev
characteristics is also described and experimental results are
given.
