In our model, the features which needed for propagation loss prediction are automatically extracted from image maps. So, it is expected that our proposed model can also predict multipath channels. In this paper, we extend our proposed DCNN-based model to multipath channel prediction and clarify its performance.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"4 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":"114709156","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}

This model solves the problem of ineffectively transmitting the information in front of the drill pipe to the ground during lateral well drilling. This paper innovatively proposes a helical coil antenna in lateral wells. Compared with the traditional insulating gap structure, the helical coil antenna has a better transmission effect. Through the simulation analysis of this model, a series of transmission characteristic diagrams of lateral wells are obtained. The results show that the electromagnetic transmission model of the lateral well using the helical coil antenna has a better transmitting ability, providing a theoretical reference for solving practical engineering problems in the future.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"44 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":"132077169","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 simulated results showed that loading the proposed PEs and BLs onto the four PIFAs could reduce as well as maintain all mutual coupling for less than -10dB, which are acceptable levels for MIMO antennas, and simultaneously improve impedance matching.
