The simulation results show that the antenna can work at 2.33-2.54 GHz, 3.24-3.91 GHz and 4.80-8.07 GHz, covering the WLAN 2.4/5.2/5.8GHz, WiMAX 3.5/5.5GHz and 5G bands. To test the flexibility of the antenna, the antenna was rolled on a cylinder with two radii $R=mathrm{10mm}$ and $R=mathrm{50mm}$. The flexible, compact, simple design and multi-band performance proves that the antenna is suitable for integration in flexible electronic devices.","PeriodicalId":428997,"journal":{"name":"2019 International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM)","volume":"59 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121006294","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}

MUSIC algorithm can effectively estimate the DOA of signal source, but the resolution of MUSIC algorithm will be reduced or even invalid with low signal-to-noise ratio (SNR) and small signal interval conditions. This paper studies an improved MUSIC algorithm which can effectively estimate DOA of signal sources with low SNR and small signal interval conditions. At the same time, the joint parameter estimation based on the MUSIC algorithm is applied to uniform linear array. The simulation results show that the DOA of the signal can be clearly distinguished from the polarization domain and the spatial domain.","PeriodicalId":428997,"journal":{"name":"2019 International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127867707","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}
