The transponder is designed to oper- ate with FMCW-based radars, commonly found in automotive and other civil applications. In particular, the device is designed such that it is very agnostic in terms of the radar sensor waveform details. The transponder can be used for different purposes, but two main application areas are presented in this paper: 1. Usage as an artificial target with applications in radar calibration and 2. Usage to simultaneously localize (using the radars ordinary functions) a target and receive small packages of data, similar to RFID, but operating together with mm-wave FMCW radars.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"249 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131920455","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}

Its radio access is random at time and frequency, and can degrade the network performance. We propose to apply signal combining and interference cancellation technologies across multiple base stations in UNB networks, in order to take advantage of their spatial diversity. We evaluate and compare the performance enhancement of each technology, compared to single BS case. These technologies exploiting multi-BS diversity are proved to be significantly beneficial in improving UNB networks’ scalability. We can gain until 28 times better performance with one iteration global SIC. We highlight that these results provide us a choice among the technologies according to the improvement needs and the implementation complexity.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128315197","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}

It is principally based on Uzkov’s theory, who define the possibility to obtain a high directivity in order of $N^{2}$ in a desired direction by linearly associating a large number N of radiators closely spaced. A first study is made by exciting monopoles by specific currents excitation in magnitude and phase to obtain a superdirectivity reconfigurable in a desired direction. Secondly, to reduce until eliminate mutual coupling between monopoles, we excite one of monopole by a & [1]. However, the most significant works for a large number of associating radiators is from I.Uzkov [2], who states in 1946 the possibility to make a superdirectivity, meaning a directivity in order of $N^{2}$, by linearly associating a larger number N of closely spaced radiating elements. Then, he showed from equations (1) and (2) defined below that this directivity can be in a desired direction $(theta ,varphi )$ when radiating elements are properly excited. unit current and loaded the other one by an impedance determined from uzkov’s theory. Simulator Ansys HFSS is used to calculated impedance matrix $H_{mn}$ of monopoles antennas array and then currents excitation coefficients $a_{{0} {n}}$ used after to determine impedance $Z_{load}$. Simulations show approximately similar results in the 2 cases with a reconfigurable directivity a least in around of $8 . 5 dB$ in a desired direction.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128668667","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}

This method is called Spectral Ray Tracking (SRT) and uses the PWS of the source fields truncated by the guide or cavity aperture. Fields at any observation point in any complex media are expressed as a discrete sum of all contributions from ray tubes, which are tracked within the propagation environment following the usual Geometrical Optics rules. The calibration uses an adaptive calculus method in the context of the multiple reflections that is faster and less hungry in memory space than fixed sampling rate used in classic methods. Moreover, it shows promising of numerical efficiency and precision.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132750663","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 integration of antennas and electronics means that measurements at antenna connectors are not possible. Regulatory limits for unwanted Radio Frequency (RF) emissions are currently set in terms of Total Radiated Power (TRP). With no antenna connectors, Over-the-Air (OTA) methods for TRP of unwanted emissions are needed. Major challenges are: large number of angular points for electrically large devices at mm-wave frequencies, and large number of possible antenna configurations per frequency. Herein, an OTA TRP measurement method based on power density measurements on a spherical surface in an anechoic chamber is investigated.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125867359","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}

In this paper, it is proposed to explore the implementation of a computational interferometric imaging solution in the millimeter band, making it possible to limit the number of signals to be measured by a multiplexing operation carried out passively and in the physical layer with the use of electrically large cavities. This approach is studied within the framework of a numerical study then of a proof of experimental concept in the W band.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"111 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126103233","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}

This sensor could be able to sense changes in the composition of the different tissues in the upperhemisphere of the head by noticing a difference in the propagation of the microwaves, as the bone injury from the craniotomy heals over time.
