摘要：—in this paper, an improved metal-backed RFID
tag antenna is presented. The proposed antenna is designed to
operate at 915 MHz with MONZA3 RFID chip. Ground
material effect is studied for different material cases. The
designed antenna achieves very good radiation characteristics
with directive main lobe, and good impedance matching, which
makes it suitable for metal-objects RFID applications. Then
testing the antenna with seven different soil samples taken
from Riyadh city following results show the different electrical
properties of seven different soil samples taken from Riyadh
city. Moreover, the results illustrate the effect of the water
content effect on the soil properties. The measurements are
done using DAK kit provided by SPEAG Company. The
measurements are done over two frequency bands, the first
from 850 MHz to 950 MHz, while the second one from 1 GHz
to 5 GHz.
