The main drawback of this type of measurement is the acquisition time that, depending on the electrical size of the Antenna Under Test (AUT), could be very long. This is due to the fact that, in order to correctly evaluate the Far Field (FF) with the NF/FF transformation [1]-[3], the NF has to be sampled over the full sphere with a sampling density that increases with the dimension of the so called AUT minimum sphere [3]. In many spherical NF measurement scenario, it is not possible to locate the AUT in the origin of the measurement sphere resulting in a larger minimum sphere, which implies a denser sampling and a longer acquisition time. An innovative NF/FF technique that allows to drastically reduce the samples density in offset spherical NF measurement is presented in this paper.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"61 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76581533","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}

Universidad Carlos III de Madrid has developed a new topology to cover them. The new receiver topology is based on a log-spiral antenna printed on a conical surface. Two interesting characteristics are presented: the first one is the dual circular polarization compared with the dual linear polarization recorded in the state of the art [2]. The other comes from the fact that the new topology uses the self-complementary antenna concept, so constant and almost real part of input impedance is obtained, simplifying the design of Low Noise Amplifier (LNA.) An array of four elements is presented for getting all the mentioned requirements. A single ended LNA covering the whole band is also presented together with the proper balun for feeding the antenna.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"34 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77603902","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}

A 2.5 D TLM based modal algorithm is developed and used to model several tunnel environments, namely an arched tunnel, a metallic tunnel and loaded tunnels with traffic. To analyse wave propagation in these context, a modal nomenclmature is proposed. Depolarisation effects have been demonstrated for arbitrary cross-sections. This effect, often observed during measurement campaigns has been shown with a numerical model.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"34 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79440947","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}

At the first step we introduce the mobility model on the example of the pedestrian motion and discuss its parameters for different environments. The impact of mobility on the system performance is estimated by comparison of channel properties vs. mmWave IEEE 802.11ad system parameters. The considered channel characteristics are calculated on the base of the Quasi-Deterministic (Q-D) channel model developed in MiWEBA project and available experimental measurement data. It is shown that mobile pedestrian channel is frequency-selective but stationary on the signal frame duration. The long-term mobility impact on the communication system performance is investigated on the PHY layer for signal bandwidths 500-2000 MHz. It is demonstrated that the system with wider bandwidth demonstrates 2-4 dB gain over the narrow-band one.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"19 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85214314","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 cloaking metasurface consists of an array of closed ring resonators, which allow an efficient phase manipulation along the edge of the bump. The numerical results at operation frequency f0 = 80 GHz demonstrate a good performance of the designed cloak in both near field and far field.

The antennas are designed using groove gap waveguide, ridge gap waveguide and inverted microstrip gap waveguide technology. All these three antenna designs are based on the cavity-backed slots as the core radiating elements. There exists a coupling slot in the cavity layer which allows the excitation of the radiating slot elements using three different types of feeding waveguide section. The designed three antennas have 16×16 radiating slot elements and these antennas operate over 15% relative bandwidth from 57-66GHz frequency range with -13 dB reflection coefficient. The simulated directivity for these slot arrays are about 33.3 dBi at the center of the band.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"7 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85617913","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}
