Abstract
Due to the fast growing of automatic processing in the majority of industrial applications,
use of RFID technology is almost mandatory. These systems must identify, with high accuracy,
objects placed at different angles or objects placed in harsh environments. In this paper,
a new design of an HF RFID reader antenna is proposed, which uses a multi-loop configuration.
This configuration ensures a uniform magnetic field on its entire surface, even if the antenna
is placed on or very close to a metallic plane. The structure of the proposed antenna is
mathematically modelled and computer simulated, as a proof of the concept, followed by
a validation on an experimental prototype. Results confirm an increase of up to 9 times
for the reading distance, compared with a standard HF RFID reader antenna, working in
the same environment. The proposed model can be used in order to improve the accuracy
of RFID tag identification in real life applications.
