The existing MOR-based neuro-TF methods avoid the issue of order-changing in modeling the electromagnetic (EM) behavior, but introduce a new issue of “pole/zero-mismatch” for the neuro-TF with the pole-zero format. In this paper, two different methods are used to address this issue. The first method exploits the sensitivity-based pole/zero-matching technique to obtain the correct correspondence between poles/zeros and geometric parameters. The second method exploits the MOR-based rational neuro-TF format to naturally eliminate the issue of mismatch. Each method is verified with an application example. Both methods achieve better modeling accuracy within the same geometrical variations than the existing methods.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133194530","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}

Comparing the active standing-wave ratios of them, the introduction of dummy elements can effectively improve the characteristics of marginal excited elements, especially when the antenna scans at a large angle. Comparing the radiation performance of them, dummy elements weaken the radiation fields of marginal excited elements and reduce the gain because the energy coupling from marginal excited elements to dummy elements is largely absorbed by the load.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115708077","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}
