ABSTRACT: This paper describes the design of a battery-assisted Ultra-High
Frequency (UHF) Radio-Fre- quency IDentification (RFID) tag suitable for
embedding in concrete materials and its measurement in a mortar slab. The
device is built to communicate wirelessly not only the ID number of the RFID
chip but also the digitalized output of a strain gauge sensor. Design
optimizations of the RFID antenna is based on published permittivity and
conductivity values of concrete. Experimental read ranges are measured from 800
to 1000 MHz with the help of commercial test equipment. Reading is possible up
to 50 cm from the surface of a mortar block for a tag embedded 5 cm below the
surface. This result is the first published one for RFID tags embedded in
concrete or mortar.
