Three sensing antennas with different substrates are designed and their structural deformation due to different types of applied strain is theoretically analyzed. These theoretical deformation results are used to calculate the corresponding resonance frequency and quality factor deviation to determine the maximum amount of stress the antennas can tolerate.

The use of a thin-film, slotted waveguide sleeve around a standard unplasticised polyvinyl chloride pipe is proposed. Wireless interrogation of the slot with a plane wave excites a resonant mode whose frequency is dependent on the dielectric permittivity within the pipe. The proposed method allows for measurements to be taken in situ with no need for samples. The device has good potential for very low-cost monitoring applications, which may require real-time, continuous assessment.","PeriodicalId":307742,"journal":{"name":"2015 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128513126","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}

One monopole rod antenna has been used as single input and eight numbers of electromagnetic coupled microstrip circular patch antennas as multiple output antenna. The system has been designed and simulated in S Band using the software tool Ansoft HFSS and developed by photolithography based wet chemistry process.
