Item type:Publication, Characteristics of specifically designed tags placed on a dielectric material(2014-01-01); ; Torrungrueng, DanaiA proposed folded dipole tag antenna for a radio frequency identification (RFID) sensor system is employed to determine qualities of a material under test (MUT). In this paper, a study on the characteristics of specifically designed tags (SDTs) placed on a dielectric material with a gap is presented. The CST Microwave Studio is used to study characteristics of these SDTs in the presence of an MUT near or contact with SDTs. Simulated results show that different SDTs provide different characteristics depending on MUTs. © 2014 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Dual-Band Band-Stop Filter for Chipless RFID Sensor in a Dielectric Constant Determination(2022-01-01); ; Torrungrueng, DanaiThis paper presents the dual-band band-stop filter to operate with the chipless RFID tag acts as the RFID sensor for a dielectric constant determination and the identification characteristic based on the signature responded signal from the chipless RFID sensor system. The proposed dual-band filter can generate the dual-stop band of the frequency of 2.2 GHz and 2.7 GHz. The 3-bits identification (ID) i.e., ID-01, ID-10, and ID-11 are obtained from the proposed filter. In addition, the chipless RFID sensor with band-stop filter technique can be determined the dielectric constant of RT/Duroid5880, Fr4 (Glass Epoxy), and low-Temperature cofired ceramic (LTCC). - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Dual-Band Band-Stop Filter using Multiple Hexagonal Microstrip Line for Chipless RFID Sensor(2023-01-01); ; Torrungrueng, DanaiThe dual-band band-stop filter using a hexagonal-shape microstrip line is presented in this paper. The chipless RFID with the band-stop filter used to determine the relative permittivity of material under test and identify characteristic based on the unique responded signal from the chipless RFID sensor. This paper proposed the multiple microstrip line structure with a quarter-wavelength transformer to generate an identification (ID) code, i.e., ID-01, ID-10, and ID-11 at the center frequency of 2.2 GHz and 2.7 GHz. From the results, the proposed chipless RFID sensor can be identified and determined the relative permittivity of the LWC. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Characteristics of an RFID sensor for a different number of reinforced metal bars in lossy light weight concrete(2015-04-22); ; Torrungrueng, DanaiThe radio frequency identification (RFID) sensor technique applied to detect a different number of reinforced metal bars in a lossy light weight concrete (LWC) is presented. The proposed dipole antenna with inductive loop is employed as an RFID sensor. A different number of reinforced metal bars are studied through the characteristics of the RFID sensor placed on LWC. Simulations are performed using the CST Microwave Studio simulation program. It is found that the reinforced metal bars in LWC have important effects to the antenna gain of the RFID sensor. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Effects of tag location on light weight concrete for an RFID sensor application(2012-10-02); ; ; Torrungrueng, DanaiThe radio frequency identification (RFID) tags are proposed to be employed as remotely read dielectric-property sensors to determine qualities of some construction material products (CMPs); e.g., light weight concrete (LWC), mortar specimens and concrete. This paper presents a study of the characteristics of an RFID tag mounted at several locations on the LWC. The numerical simulations are performed using the CST Microwave Studio to study effects of tag, where the folded dipole with an inductive loop tag antenna is used. Results show that locations of an RFID tag on LWC affects the tag antenna characteristics such as input impedance, gain and radiation pattern. © 2012 IEEE. - Some of the metrics are blocked by yourconsent settings
