A miniature PIFA RFID tag antenna for metal surface applications is presented in this article. The RFID tag antenna has a compact size ($45text{mm}times 45text{mm}times 5.162text{mm}$) UHF, with a high gain of 4.2dB and a long maximum read range of 25m. The designed antenna is a two-substrate PIFA whose radiating plane, made of copper, is printed on Rogers RT / duroid 5880 ($varepsilon_{r}=2.2, text{tan} sigma=0.0009$), the artificial magnetic conductor (AMC) and the ground plane are printed on top and bottom of FR4 epoxy substrate ($varepsilon_{r}=4.4, text{tan} sigma=0.02$) respectively. The antenna is connected to the Monza R6 chip of impedance $mathrm{Z}=13.6-mathrm{j} 127$ at 866 MHz. It covers a bandwidth of 780 MHz (570 MHz-1.35 GHz) and therefore it covers the entire European UHF RFID band. To test its robustness, this tag antenna is simulated on different metal plates but these do not affect the performance of the tag.

In this work, an antipodal Vivaldi antenna optimized with different metalenses for wideband applications is designed. This light-weighted antenna is wideband and exhibits good gain in the whole bandwidth. The employment of metalenses with variable metamaterials dimensions allows to increase maximum gain of about ΔG = 2 dB in the frequency band f = 7 – 10 GHz, without reducing the working bandwidth of the antenna. Prototypes have been fabricated and characterized, showing good agreements with simulations.

This work presents a circularly polarized side-edge microstrip antenna for (5G) smartphone and Wi-Fi 6 applications. The designed antenna consists of several microstrip lines arranged in a way to produce dual operating bands, in the (5.32 – 5.52) GHz band and (6.15 – 6.36) GHz band with a percentage bandwidth of 3.69 % and 3.36 % respectively corresponds to 200 MHz and 210 MHz bandwidth for the two bands. The proposed single-element antenna is placed on the top portion of the FR-4 substrate side edge frame and fed by a coaxial SMA connector. The achieved results have exhibited reasonable antenna characteristics in terms of investigated reflection, gain, efficiency, radiation pattern, and impedance matching for the two resonating bands.

This research describes a bio-inspired antenna design derived from the shape of a three-petal flower intended for multiple agilities. The proposed design incorporated three PIN diodes corresponding to 8 modes of operation, to achieve pattern diversity and multiple frequency reconfigurable bands. The diodes have been connected between the main hexagonal microstrip radiator and the external parasitic elements, which have a flower petal shape. Pattern reconfigurability has been achieved at 4.675 GHz and 5.2 GHz frequencies, and multi-band frequency reconfigurability was achieved at various center frequencies within the C-band from 4 to 8 GHz range where it can support modern applications such as 5G NR (new radio) and Wi-Fi 6 communications.

In this paper, some numerical results on the possibil-ity to design a 3D-printable dielectric ReflectArray (RA) antenna with beam steering capabilities are presented. The adopted unit-cell consists of a single-layer dielectric element perforated with a square hole, whose side is varied to change the phase of the reflection coefficient. Since the unit-cell behavior is quite stable with the direction of arrival of the incident field, it is used to design a 52 × 52 reflectarray working in Ka-band. Its numerical characterization proves that the RA is able to provide less than 2 dB of gain losses over a scanning range of ±30° in the vertical plane.

In this paper, we investigate the short-circuit calibration step of the open-ended coaxial probe (OECP) which is one of the major challenges when measuring complex dielectric permittivity (CDP) of a material under test (MUT). The effect of short-circuit inaccuracy can be mitigated by an alternative calibration approach by taking advantage of the calibration mathematical model of the OECP and using known liquid instead of the commonly used metallic short-circuit procedure. The CDP results of formamide and Dimethyl Sulfoxide (DMSO) as the MUT are compared using three known liquids acetone, butanol, and 2-propanol respectively, as the shorting material during the calibration procedure. The MUT and calibration liquids were simulated with Ansys HFSS simulation program from 0.5 to 6 GHz frequency range with a resolution of 0.25 GHz. The commercially available Speag DAK 3.5-mm OECP was replicated with similar material specifications and dimensions. In order to retrieve the CDPs from reflection coefficients (RCs) obtained from the probe-MUT interface, a multi-frequency Gauss-Newton inversion method based is implemented. The results demonstrate that it is important to select an appropriate calibration material during the calibration procedure to ensure reliable CDP results. The study also indicates that further numerical investigation is required to explain the relationship between the calibration mathematical model and CDP.
在本文中，我们研究了开放式同轴探头(OECP)的短路校准步骤，这是测量被测材料(MUT)的复介电常数(CDP)时面临的主要挑战之一。短路不准确的影响可以通过另一种校准方法减轻，即利用经合组织的校准数学模型并使用已知液体代替常用的金属短路程序。在校准过程中，分别使用三种已知液体丙酮、丁醇和2-丙醇作为短路材料，比较了甲酰胺和二甲基亚砜(DMSO)作为MUT的CDP结果。利用Ansys HFSS仿真程序在0.5 ~ 6ghz频率范围内对MUT和校准液进行了仿真，分辨率为0.25 GHz。市售的Speag DAK 3.5 mm OECP具有类似的材料规格和尺寸。为了从探测器- mut界面反射系数(rc)中提取cdp，实现了一种基于多频高斯-牛顿反演的方法。结果表明，在校准过程中选择合适的校准材料对于确保可靠的CDP结果非常重要。该研究还表明，需要进一步的数值研究来解释校准数学模型与CDP之间的关系。

Screen printing of a Frequency Selective Surface (FSS) on a plasterboard block to curtail the drop of wireless signals within indoor settings is described in this paper. The proposed low-cost FSS solution operates at a central frequency of 2 GHz and covers some of the existing mobile phone frequency bands. An array of square loop elements is used for this application. The array structure was printed with the help of a screen-printing setup on a plasterboard using Dycotech silver paste. Simulated transmission responses compared well with measurements. The FSS was simulated using CST Microwave Studio™. Screen printing allows the direct printing of FSS on the uneven and porous surfaces of plasterboards with the details necessary for various microwave and mm-wave applications and provide the necessary conductivity for filtering. The intended application is the production of plasterboard FSS as a building material with embedded RF properties.

The problem of the scattering of an E-polarized plane wave from 2D open-ended S-shaped cavities is rigorously solved by the Method of Analytical Regularization. The obtained solution is used for full-wave analysis of backscattering. The special focus is on studies of resonance phenomena observed in the spectral dependence of the Radar Cross Section. They are explained as excitation of the complex natural oscillations in S-shaped cavities.

Over the past 30 years, the consumption of fresh fruits and vegetables in industrialized countries has increased, along with the circulation of goods on a world-wide scale. This implies the risk of outbreaks of food poisoning and food infections related to consumption of fresh fruits, as well as a huge increase in the risk of wasting impressive amounts of products. To reduce this waste, Radio Frequency Identification (RFID) systems can be beneficial, enabling early detection via low-cost tagging of contaminated vegetables and fruit, which can help reduce these losses and stop the spread of disease. An inexpensive sensor antenna has been designed using a sensitive substrate in this paper. In order to estimate the freshness of mangoes, this design optimizes the matching of input impedance based on the surface permittivity changes of the substrate The analysis of the dielectric characteristics of Tommy Atkins Mango data is used so to investigate the maturation, ripping and freshness of mangos. Using the proposed approach, it was demonstrated that a smaller sum of dielectric constants, leads to greater contribution of the substrate and the performance of the antenna is as follows: resonant frequency and S-parameter amplitude tend towards 1 GHz and −33.37 dB, respectively.
