The antenna structure is made up of two layers of substrate, an ellipse radiating shape, and an ellipse slotted parasitic patch. Circular polarization is generated by rotating the ellipse 45 degrees relative to the y axis. In this proposed antenna, a single proximity feed has been adopted. The finite element method (FEM) was operated to optimize the design and achieve good circular polarization at the center frequency of 5.3 GHz. The proposed antenna dimension was optimized with a relative dielectric constant of 2.17, a loss tangent of 0.0005, and a substrate thickness of 1.6 mm. The simulated impedance bandwidth and axial ratio bandwidth are 610 MHz and 475 MHz, respectively. Based on the simulated results, the design of proposed antenna can be implemented for the CP-SAR sensor.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"27 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":"129983058","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 MLAT system uses the Time Difference of Arrival (TDOA) technique to estimate aircraft positions. Consequently, the receiving status of each receiver station differs corresponding to the allocation of receivers and actual aircraft positions. In this paper, we show the amounts of signals detected at MLAT receiver stations. Furthermore, it demonstrates that the receiving status and the estimated position accuracy depend on the propagation path between the receiver and the aircraft.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"169 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":"132685865","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 attain these characteristics, we operated PIN diodes in the region below the threshold. By employing this method, the required DC voltage and current to control PIN diodes are dramatically reduced. Consequently, the proposed broadband absorber provides not only a switchable absorption property but also a low DC power consumption characteristic. In addition, it also possesses a polarization-insensitivity due to its symmetric structure and well-isolated bias lines from an RF signal. The measured results agree well with the simulated ones, which provides the validity of our design method.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"42 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":"126378897","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}
