The LL antenna consists of a metal reflective ground, seven hemispherical shells, and a corrugated horn. The approximate permittivity of each shell is realized by inserting air holes with different ratios of dielectric and air. The LLs with vertical and radial holes are designed and simulated, respectively. The corrugated horn antenna is utilized as the feed source for the lens due to its rotationally symmetric pattern. A Luneburg lens whose diameter is 240 mm is designed and manufactured by 3D printing technology. The simulation results confirm that a peak gain of 28.4 dBi with a 1.2 dBi gain fluctuation at 12.5 GHz of the LL antenna can be achieved.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121182967","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}

Using the ranging-based method for target localization only needs a single antenna, which is very suitable for size-constrained IoT devices. However, phase errors due to the lack of time synchronization between the transmitter and receiver and multipath effects usually seriously affect the accuracy of ranging. This paper uses the two-way channel response to eliminate the phase errors. Then, the generation of additional unknown multipath signals is suppressed by taking the square root of the two-way channel response. Finally, the orthogonal matching pursuit (OMP) algorithm is used to estimate multipath signals. Experiment results show that the proposed method can achieve high-precision ranging in indoor multipath environments.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132516263","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}
