In this paper, we propose a super-resolution algorithm based on sparse recovery to estimate the parameters of WiFi signal. Specifically, we first jointly esti-mate the Angle of Arrival (AoA) and Time of Flight (ToF) using sparse recovery. Then, we use time alignment and singular value decomposition with multiple channel state information packets to obtain more accurate parameters. We conduct experiments in an actual indoor environment, and the experimental results show that this method can obtain accurate parameters.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132977751","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}

An aperture coupled feed mechanism and dual-layer radiating patches are adopted to achieve wideband impedance matching. Due to the piled dielectric slabs, the performance of microstrip antenna arrays is normally deteriorated by surface waves when scanning to large angles. To solve this issue, the stacked slabs have been perforated to the greatest extent to suppress surface wave propagation. Additionally, two pairs of parasitic strips have been designed to improve the antenna performance in the lower band without increasing the antenna profile. The thickness of the array is only $0.19lambda_{h}(lambda_{h}$ refers to the wavelength at the highest operating frequency in free space), indicating the good potential for low-profile applications. The proposed array antenna has achieved relative bandwidths of 57.9% (active VSWR $leqslant 2.25$) and 44.4% (active VSWR $leqslant 2.75$) for $pm 45^{circ}$ scanning and $pm 60^{circ}$ scanning, respectively.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130705437","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}

Specailly, indoor localization using a single access point with the multipath triangulation has been obtained great attentions, in which the reflection path is considered as “friend” instead of “enemy” compared with the traditional localization methods. However, the prior systems do not dive into the impact of the shape of the multipath triangle on the localization accuracy. So, in this paper we investigate this factor deeply and propose a method that make better use of multipath triangles for improving the accuracy.

Flip chip packaging technology is used to complete the chip and Pcb substrate interconnection and the DC bias circuit is led out through metal holes. Simulation results show that by changing the state of S-PIN switch, the antenna can switch between horizontal polarization and vertical polarization, and can achieve frequency reconstruction from 7.45GHz to 16.5GHz respectively.
