In the proposed 3D Tempered Glass-Covered Metasurface Antenna-in-Package (MSAiP), tempered glass is covered on the AiP, and the metasurface is inserted between the AiP and the glass. The inserted metasurface is made through 2-port circuit modeling, and its physical size is small considering the narrow smartphone mounting space. In order to minimize the performance degradation caused by glass when AiP is mounted in a smartphone, performance optimization is carried out while AiP, metasurface, and glass are all combined. The peak gains of MSAiP are 13.5 dBi (27 GHz) and 13.1 dBi (38.5 GHz), whereas those of AiP without metasurface are 10.1 dBi (27 GHz) and 9.4 dBi (38.5 GHz). Besides, the peak EIRP (dBm)/tilting degree (°) of chip-coupled MSAiP are 6.59/0, 5.87/12, and 3.37/27. However, the results of chip-coupled AiP without metasurface are 2.01/0, 1.6/12, and −0.95/30. All these results indicate that beam coverage of AiP is improved by the inserted metasurface.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"19 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":"128221936","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}

However, the unique antenna and low power constraints as a result of the small satellite package means that an antenna solution specific to this application is necessary. In this paper, we propose practicable antenna requirements that enable Ionospheric remote sensing using a 3U CubeSat. The requirements consist of gain, polarization, phase center, and mechanical parameters. To demonstrate the practicality of the requirements, simulation results of a preliminary antenna design are presented.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"7 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":"129315482","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}

Beamforming can be used in these phased arrays to receive desired radar returns and to suppress unwanted returns and interfering signals. Usually, the number of interferers and their location is not known or may vary. Also, the distance from interferers to the SAR varies. Here, a new robust beamforming algorithm is proposed for the case when the interferers are distributed with a specific distribution. This algorithm is applied to a satellite case study and the results are compared with the equi-sidelobe beamformer.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"29 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":"129362833","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 proposed gap waveguide consists of a top conductor plate, a bottom dielectric substrate with mushroom-like EBG elements, and an air layer between them. EBG elements prevent a leakage from the gap waveguide in the air layer and can be manufactured cost-effectively with PCB processes. Transmission loss of the gap waveguide is analyzed by numerical simulation with ANSYS HFSS at 4.7 GHz. It reveals by the simulation that smaller transmission loss of the gap waveguide of less than 1 dB/m is obtained for the cases of a large distance of the EBG elements, a large width of the ridge conductor, and a small height of the air layer in comparison with a microstrip line with the same dielectric substrate.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"26 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":"124974040","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}
