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.","PeriodicalId":124088,"journal":{"name":"2022 Microwave Mediterranean Symposium (MMS)","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123557683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":124088,"journal":{"name":"2022 Microwave Mediterranean Symposium (MMS)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121425630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simulated transmission responses compared well with measurements. The FSS was simulated using CST Microwave Studio™.

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.","PeriodicalId":124088,"journal":{"name":"2022 Microwave Mediterranean Symposium (MMS)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134078616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
