    ABSTRACT: A 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.

    ABSTRACT: The proposed antenna is a circular microstrip structure excited by four feeds and suspended with artificial magnetic conductors (AMCs). The multifeed circular microstrip antennas can generate a high circularly polarized performance by using a different feed arrangement. AMC structures with a square, circular, or octagonal patch on a unit cell are designed and applied to circular microstrip patch antennas for the enhancement of antenna performance. It is found that simulated results of the proposed antenna are well suited. The properties of wide beamwidth with good axial ratio can be achieved when applying the proposed AMC structures to circular microstrip antennas. The antenna prototype was fabricated to validate simulated results.

    ABSTRACT: The electromagnetic (EM) wave radiation of the C-slot radio frequency identification (RFID) tag located on the impedance surface in this paper is analyzed using the uniform geometrical theory of diffraction (UTD) solution. The UTD radiation solution for the impedance curved surface is employed to predict the EM wave radiation of the RFID tag mounted on the impedance curved product surface. The UTD radiation solution provides the physical insight of the EM field at the observation point and requires less computational time than the other numerical methods. The results show that the UTD radiation solution can accurately predict the radiation pattern of the proposed C-slot RFID tag mounted on the product. The proposed tag antenna can efficiently be applied to the curved surface object, such as the curved metallic product coated with dielectric (layers of paints).

    ABSTRACT: In this paper, an efficient hybrid method is proposed for solving electrically large planar dipole antenna arrays in free space. The hybrid method appropriately combines the multiple sweep method of moments (MSMM) and conjugate gradient (CG) method, called hybrid MSMM/CG method, yielding better convergence rate compared with the conventional MSMM and CG method. Two examples of 21× 21 uniform and 24× 24 non-uniform planar dipole antenna arrays are analyzed. Results show that the hybrid MSMM/CG method converges rapidly compared to the conventional methods. In addition, the current distributions and radiation patterns computed by using the hybrid MSMM/CG method are in excellent agreement with those obtained from the standard method of moments (MM). It is found that the hybrid MSMM/CG method is very efficient and accurate for electrically large planar dipole antenna arrays in free space.

    ABSTRACT: In this paper, the simulation of radiation pattern of the proposed RFID C-slot tag antenna on a coated metallic cylindrical surface is presented. It is found that the radiation pattern in the shadow zone (behind the product) from the proposed RFID tag is stronger than that from the electric current source case (electric tag). Thus, the proposed C-slot tag antenna is useful for the RFID application especially for the curved metallic surface product.

    ABSTRACT: In this paper, the multiple sweep method of moments (MSMM) is employed to design non-uniform planar dipole antenna arrays in free space, where the genetic algorithm (GA) is integrated with the MSMM to find optimum array parameters. The antenna design is focused on parameters of non-uniform planar dipole antenna arrays, which are the length of each element, spacing between elements, and the feeding voltage of each element. Numerical results are presented to demonstrate the accuracy and efficiency of the MSMM/GA method for non-uniform planar dipole antenna arrays in free space.

    ABSTRACT: This paper presents an ultra-wideband (UWB) rectangular ring antenna excited by a circular disc monopole (CDM) with a conducting rod and two double ridges to radiate bidirectional pattern with constant beam direction along the entire UWB frequency range of 3.1–10.6 GHz. The conducting rod and double ridges at the upper wall of the ring are added to solve the tilted beam problem at the higher edge frequency whereas the double ridges at the lower wall are used to enhance the impedance bandwidth. The dimensions of the rectangular ring and the CDM are initially considered to achieve the bidirectional pattern with the suitable resonant frequencies and bandwidth. Then, the parameters of copper rod and two double ridges are determined by parametric study using CST Microwave Studio simulation software. The prototype antenna was fabricated, and the measured results show good agreement with the simulated ones. The obtained bandwidth of |S 11 | < −10 dB can cover the UWB frequency range as well as the bidirectional beam radiation with constant beam direction (θ = 0 • , 180 • and φ = 90 •). The minimum and maximum measured gains are 3.1 dBi to 5.3 dBi, respectively. The proposed antenna possesses compact size with good radiation performance that can be a promising candidate for UWB applications.

    ABSTRACT: The 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.

    ABSTRACT: This paper presents an accuracy of a modified UTD solution for a convex impedance cylinder based on the general 3D UTD solution for a smooth convex perfectly electric conductor (PEC) scattering problem. By employing the impedance boundary condition (IBC), the modified UTD solution for a convex impedance cylinder can be used for the material-coated PEC cylinder problem. Thus, the modified UTD solution for a convex impedance cylinder surface requires the surface impedance value (ZS). In this paper, the study of the limitation of approximated closed form of ZS is presented. The thickness of thin material-coated PEC cylinder will be investigated in terms of the ratio of material-coated thickness to radius of the cylinder. The mean squared error (MSE) between the modified UTD results and the reference results obtained from CST-Microwave Studio program is performed to investigate limitation of closed form of ZS. The relative permittivity εr of a material-coated PEC cylinder in this paper is fixed to 4. The modified UTD solution result shows good agreement with the CST-Microwave Studio commercial software for the dielectric-coated thickness up to d/a ≤0.07 or d≤0.14λ for a=2λ.

    ABSTRACT: In this paper, the proposed theoretical path-loss prediction procedure and measured results of radio wave propagation in an orchard environment are presented. The path-loss prediction of wireless sensor network (WSN) in a durian (Durio zibethinus Murray) orchard is chosen to be an example of this study. The three- dimensional (3-D) modifled uniform geometrical theory of difiraction (UTD) for curved impedance surface and the complex source point (CSP) technique for source modeling are employed for theoretical path-loss prediction in this paper. The orchard scenario is modeled using canonical geometries of UTD, such as a dielectric ∞at surface and cylindrical structures with an impedance surface to respectively represent ground and trees. Moreover, since the wireless sensor node is attached to the outside peel of a hanging durian fruit, the fruit partially acts as a wireless sensor node. Therefore, to obtain greater accuracy in the source radiation pattern, the Gaussian beam (GB) expansion via the CSP technique is used for source modeling. The path loss prediction from the proposed numerical procedure and the measured results are in good agreement. The proposed numerical procedure to calculate the path loss from actual scenario of the orchard is useful for network planning such as the pre-harvesting WSN system and other orchard scenarios.

The measured axial ratios at the center frequency of the UHF and the microwave band are 0.09 dB and 0.55 dB, respectively.
