Small proximity coupled ceramic patch antenna for uhf rfid tag mountable on metallic objects

This letter presents the design of a small and low-profile RFID tag antenna in the UHF band that can be mounted on metallic objects. The designed tag antenna, which uses a ceramic material as a substrate, consists of a radiating patch and a microstrip line with two shorting pins for a proximity-coupled feeding structure. Using this structure, impedance matching can be simply obtained between the antenna and tag chip without a matching network. The fractional impedance bandwidth for S 11<3 dB and radiation efficiency are about 1.4% and 56% at 911 MHz, respectively. The read range is approximately from 5 m to 6 m when the tag antenna is mounted on a metallic surface.

In this paper, we present a demodulation structure suitable for a reader receiver in a passive Radio Frequency IDentification (RFID) environment. In a passive RFID configuration, undesirable DC-offset phenomenon may appear in the baseband of the reader receiver. As a result, this DC-offset phenomenon can severely degrade the performance of the extraction of valid information from a received signal in the reader receiver. To mitigate the DC-offset phenomenon, we propose a demodulation structure to reconstruct a corrupted signal with the DC-offset phenomenon, by extracting useful transition information from the corrupted signal. It is shown that the proposed method can successfully detect valid data from a received signal, even when the received baseband signal is distorted with the DC-offset phenomenon.

Study on the demodulation structure of reader receiver in a passive rfid environment

This paper presents the design of a near-field reader and tag antennas in UHF that can be used for various smart shelves. The tag antenna is designed by introducing an “S”-shaped or “+”-shaped slot to the circular patch and the reader one is a rectangular slot array fed by a microstrip line. These antennas operated in UHF near-field are more reliable in many RFID applications where reading distance is not the major factor. Electric coupling concept between the reader and tag antenna is employed for near-field communication.
