In this paper, the design of frequency reconfigurable antenna is discussed. The reference square patch structure was optimized to operate at 2.45GHz. The frequency agility was achieved by integrating a varactor diode, a tuning range of 0.5-2.03GHz was realized. Then to improve the antenna performances, the varactor diode was replaced by a digital capacitor. A tuning range of 0.876 to 1.15 GHz was achieved with better radiation properties (impedance matching, gain...) due to the capacitor's ability to dynamically command the antenna using a binary code. Prototypes were realized for both cases. Simulated and measured results are presented and discussed.","PeriodicalId":274656,"journal":{"name":"2015 IEEE 15th Mediterranean Microwave Symposium (MMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130075120","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}

Radiofrequency (RF) energy and microwave are promising technologies to be applied in the AgroFood sector and at industry level. RF energy has been used as a means to rapidly heat nuts (almonds, walnuts, hazelnuts) to control post-harvest insects, in a rapid process able to maintain the quality and sensorial properties of nuts. Several food productions, such as dried fruits, ham, sausages, and cheese, are subject to mite infestation and contamination with bacteria and fungi. The excessive presence of mites induces a change in sensory properties and lowers the quality of stored foods. In addition, in the drying process, RF and microwave treatments reduce rapidly the moisture content and contribute to inhibit the activity of enzymes involved in lipid peroxidation, ensuring not only an extension of shelf-life, but also preserving the sensory properties and quality of the food productions during storage.","PeriodicalId":274656,"journal":{"name":"2015 IEEE 15th Mediterranean Microwave Symposium (MMS)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115116998","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}

Novel tags offer additional functionalities besides identification by embedding sensors, actuators, and processing units. In this work a new kind of device, called SPARTACUS, is presented. While being completely passive, it conjugates identification, sensing, local computing, and actuation control and enables a proactive communication with any standard RFID reader. Thanks to an accurate electromagnetic design and exploiting polarization diversity of two antennas performing both energy harvesting and communication, SPARTACUS ensures compactness, energy-efficiency, and ease of use.
