In this paper, we extracted appropriate information from a scalogram and utilized it to detect the sizes of bedsores.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132453447","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}

To achieve this, it is important to grasp the DOA (Direction of Arrival)/ DOD (Direction of Departure) characteristics. We have developed a rotating reflector antenna that can mechanically perform azimuthal beam scanning to enable DOA/DOD measurement in the 300 GHz band. In this report, we propose a DOA/ DOD measurement method that uses the rotating reflector antenna as both the transmitter antenna (Tx) and the receiver antenna (Rx). In addition, experiments using our measurement method were conducted in a shielded room in a multi-reflection environment, and its effectiveness was confirmed by comparison with ray-trace simulating.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114461154","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 T-shaped feeding structure can reduce the cross-polarization level up to 8.2 dB at lower frequencies, which makes the highest cross-polarized components around -15 dB over the whole operation bandwidth. A grounded metal strip is introduced to compensate the increase in working frequency due to the T-shaped feed.
