The configuration of the designed antenna consists of four resonators operating at the Sub-6 GHz 5G band. Each antenna element is composed of a planar-inverted F antenna (PIFA), a monopole antenna and a slot by defected ground structure (GDS). These four compact resonators are located in four corners, representing a smartphone board in practice. All radiating elements are etched on a low-cost FR4 substrate with an overall size of $150times 75times 7mathrm{mm}^{3}$. Under the impedance matching ($S_{11}leq$-10dB) of 3.3-5.8 GHz, the designed MIMO antenna has good total efficiency of 55%-87%, sufficient maximum gain of 3.5-6.0 dBi and ports isolation $leq$-15dB. The bandwidth of the presented antenna covers Sub-6 GHz 5G band of some current research hotspots including n77(3.3-4.2GHz), n78(3.3-3.8GHz), n79(4.4-5.0GHz) and others. The calculated antenna envelope correlation coefficient (ECC) and total active reflection coefficient (TARC) are low over the whole band. Moreover, the proposed design exhibits very small specific absorption rate (SAR) values at the reflection zeros of user-head.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123954318","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}

Efficient detection of process faults can help to avoid abnormal event progression and reduce productivity loss. However, in the complex process system, there are uncontrollable factors or variables which are not captured by sensors that lead to problems with the high imbalance ratio and the curse of dimensionality. It becomes more challenging for many traditional fault detection methods to diagnose the faults in the process or capture the process's hidden characteristics when the data distribution is imbalanced. Therefore, motivated by deep generative models, we proposed a variational-autoencoder (VAE) based approach which can efficiently boost the fault detection performance from imbalanced process data. The proposed approach is highly suitable for dimension reduction and feature extraction of abnormal data: fault samples with new characteristics can be generated. The prediction accuracy evaluated by state-of-the-art classification algorithms can be improved significantly. We have tested our proposed approach using one real dataset collected from a packaging production line of semiconductor integrated circuits (PoSIC), and one public dataset describes a sample of pular candidates collected during High Time Resolution Universe Survey (HTRU2). Our experimental results demonstrate that the proposed approach can be well applied to imbalance process data and significantly improve prediction accuracy.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"125 25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126793931","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}
