Abstract
Radio frequency
identification (RFID) technology
employs short-range wireless communications
to read certain digital information
stored in a tag attached to an object
being tracked. An RFID system consists
of one or more tags with IC chips,
and a read/write (R/W) device incorporating
an R/W antenna as its main component.
Tags come in many sizes and shapes,
but they are usually small and lightweight,
and are typically used for wireless
data communication with R/W devices
at distances ranging from a few
millimeters to several meters.
This short course
will cover all the technical aspects
of UHF band RFID antenna design
and applications. It will begin
with a detailed introduction of
the basic principles of wireless
communications as incorporated in
real-life RFID systems. Next, the
performance requirements of various
R/W antennas for RFID systems would
be presented. To provide simultaneous
signal reception from arbitrarily
oriented linearly polarized tags
an R/W antenna is typically designed
to be circularly polarized (CP),
with its polarization characterized
by the axial ratio (AR), although
it is possible to use linearly polarized
(LP) R/W antennas in some RFID systems.
Several designs of CP and LP R/W
antennas, as well as RFID tag antennas
will be presented and their implementation
in various RFID systems will be
described. Some of the topics to
be covered are listed below:
1.
Design and optimization of
high-gain single feed RHCP and LP
parasitic R/W patch antenna.
2.
RHCP and LP 2-element dipole-on-glass
R/W antenna for show case applications.
3.
Design and system integration
of printed-on-glass RHCP R/W gate
patch antenna.
4.
Environmental effects on
the performance of high-gain RHCP
R/W patch antenna located outdoors.
5.
Simulation and design of
custom-made RFID tag antennas and
their implementation.
6.
Design of platform tolerant
tags, including those operating
efficiently when placed on metallic
objects.
7.
Example of special-purpose
RFID tags, e.g., those designed
for libraries.
8.
Tracking and measuring speeds
of moving RFID tags.
