The paper concludes that the excess loss, i.e., the loss in addition to the free-space path loss, is very similar for 28, 58 and 143 GHz as long as the measurements are conducted in open areas or where only one or two reflections are needed to get coverage. In areas requiring multiple reflections or wall penetration to achieve coverage, the excess loss increases for the higher frequencies.","PeriodicalId":228461,"journal":{"name":"2022 16th European Conference on Antennas and Propagation (EuCAP)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123319523","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}

With full Joint Communication And Sensing (JCAS) support, increased bandwidth and higher frequency bands expected for sixth generation (6G) communication systems, a new horizon on the usage of cellular radio frequency (RF) signals for joint air-to-ground (A2G) communications and precise environment sensing is open. In this short paper, the basics of a Deep Learning (DL)-based approach for environment sensing from a UAV by using RF signals from terrestrial cellular deployments is presented. Preliminary results prove that the achieved accuracy of the location of scatterers on the environment is currently around 1 m. The proposed approach constitutes a totally autonomous JCAS solution for environment sensing whose accuracy could be even further improved by learning from previously captured data.","PeriodicalId":228461,"journal":{"name":"2022 16th European Conference on Antennas and Propagation (EuCAP)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122552327","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 semian-alytical methodology, avoiding full-wave optimization, enables replacement of the generally-large number of active radiating elements with passive capacitively-loaded wires (meta-atoms), without sacrificing array directivity. Contrary to common techniques to dilute arrays, relying mostly on optimization of active element distribution and excitation, our modular solution utilizes a standard array configuration with linearly-phased elements; grating-lobe suppression is achieved by proper engineering of the passive MG, harnessing Floquet-Bloch formalism to control power partition into diffraction orders. To facilitate dramatic dilution and comply with printed-circuit-board (PCB) design requirements, we extend our previous work, enabling inclusion of multiple meta-atoms per period within a multilayered dielectric substrate. This concept, verified via full-wave simulations, is expected to facilitate the development of low-cost, planar, low-loss, and highly-directive antenna systems for future cellular and satellite communication.","PeriodicalId":228461,"journal":{"name":"2022 16th European Conference on Antennas and Propagation (EuCAP)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122728851","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 latter are linked with the same roots of the equation mentioned, computed at other assumptions and have been defined and discussed by the authors in earlier studies.

It has been shown that, for a given reflection magnitude, capacitive PRS facilitates a larger antenna gain than inductive PRS, based on leaky-wave model and practical design examples. In this paper, we extend the classical ray-tracing approach to derive analytically that the superior gain is primarily due to the greater height of the capacitive PRS from the ground plane, which leads to a smaller phase delay and a more uniform magnitude distribution across the PRS. To verify the analytical study, the simulated phase and magnitude distributions of a capacitive and an inductive PRS antenna were produced and shown to agree with the predicted trends of the phase and magnitudes distributions from ray-tracing. The gain of the antenna with the capacitive PRS is 16.6 dBi, which is 1.8 dBi higher than that of the antenna with the inductive PRS. This insight on the effect of PRS height on phase delay gives more clarity to the operating principle of PRS antenna.","PeriodicalId":228461,"journal":{"name":"2022 16th European Conference on Antennas and Propagation (EuCAP)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122130410","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}
