Thus, miniaturized tags that achieve read ranges of several meters are of major interest for these applications. In this contribution, the design of a small antenna to tag metallic items is presented. It achieves a maximum read range of 13.3 meters and its dimensions are 14.3 × 25 × 3 mm3. The proposed design consists in a short-ended parallel plate. It is mounted on a ceramic substrate to obtain the required miniaturization. A comparison with the smallest tag designs found in the literature will be also carried out.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"7 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87995155","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}

Essential to its realization is a novel ultra-wideband array that incorporates suitable balanced feeds. Also, unique bandwidth reconfiguration technique is presented via simple tuning of the balanced feed behind antenna elements to null sensitive RF bands. Finally, a broadband beamforming is proposed with reduced power requirements using a much smaller number of analog-to-digital converters and on-site code division multiplexing technique.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"7 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80225311","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 purpose was to investigate the amount of attenuation due to precipitation, especially rain and wet snow, and its yearly variations. The attenuation of the radio link signal was measured. The measured attenuation results are compared to the models given by the International Telecommunication Union (ITU). The predominant cause of fading was rain and wet snow. The fading due to combined rain and wet snow is underestimated by ITU-R 530-15 [1]. Also measurements of fading speed, fade duration, number of fades and polarization correlation are presented.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"51 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91121422","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 frequency band of observation is from 1700MHz to 2700 MHz, covering the UMTS and LTE communication bands. This bandwidth is chosen to show the broadband effects on the scattering parameters as well as on the radiation patterns. For the radiation behavior the focus is on the differences between a constant and a frequency dependent half power beamwidth.

Theoretically, the new structure may be considered as a two layer shielded structure where the bottom layer consists of an array of periodic metallic pins which works as an artificial magnetic conductor (AMC). However, it is difficult to evaluate electromagnetic properties and performance of the new waveguide by using traditional waveguide ports or discrete ports in available full-wave simulator. In order to solve the problem, this paper proposes an effective method to determine dimensions of traditional waveguide ports in existing commercial full wave simulator to be used while simulating the inverted microstrip gap waveguide structures. The procedure includes the analysis of quasi-TEM mode of the inverted microstrip gap waveguide and the corresponding size of the waveguide port, as well as the location and boundary conditions used in the simulation software. The numerical port proposed in this work is much better than the ports used previously.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"220 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73814336","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 medical imaging applications, the illposedness and non-linearity of the electromagnetic (EM) inverse problem still represents a big challenge before moving to clinical trials. This paper applies a novel thresholding algorithm to the linear inversion at each iteration of the Distorted Born Iterative Method (DBIM), which is amongst the most popular algorithms that deal with the EM nonlinear problem.
