The antenna is composed of two circular coplanar strips which enclose slot aperture of similar shape and is designed on a thin and flexible substrate. From the modeling and experimental tests the antenna shows good performance in 2-15GHz frequency range with return losses better than 10dB. It is shown that the proximity of different, non-metalic materials does not significantly affect antenna performance. The proximity of metalic screens deteriorates its radiation pattern and reflection coefficient. However with the correct choice of the distance between screen and antenna the required level of return losses can be provided.","PeriodicalId":22362,"journal":{"name":"The 8th European Conference on Antennas and Propagation (EuCAP 2014)","volume":"35 1","pages":"3097-3100"},"PeriodicalIF":0.0,"publicationDate":"2014-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73515845","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, we elucidate the relationship between superoscillation and the closely related concept of superdirectivity. Key similarities and differences are highlighted, which showcase windows of possibility for practical superoscil-latory waveform design. Thereafter, through the example of the Optical Super-Microscope - a far-field super-resolution microscope, we demonstrate how established antenna array theory can be leveraged to design a practical superoscillatory filter, which enables far-field sub-diffraction optical imaging. We end by reporting our current progress with the Optical Super-Microscope and suggest future directions to improve its imaging capability.","PeriodicalId":22362,"journal":{"name":"The 8th European Conference on Antennas and Propagation (EuCAP 2014)","volume":"28 1","pages":"1340-1344"},"PeriodicalIF":0.0,"publicationDate":"2014-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73655801","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 goal of the propagation work in METIS is to provide adequate propagation models for 5G. For this purpose corresponding deficiencies of present commonly used models are identified. Further, the lack of available channel models for several propagation scenarios has been assessed. Based on this assessment the framework of 5G channel modelling is sketched. As propagation measurement campaigns are a crucial part of this work they are illustrated with a few examples.","PeriodicalId":22362,"journal":{"name":"The 8th European Conference on Antennas and Propagation (EuCAP 2014)","volume":"12 1","pages":"219-223"},"PeriodicalIF":0.0,"publicationDate":"2014-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75792175","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}

Two different sensor locations are considered; one near the elbow and one on the chest.

Results show that accuracy in estimation of location of the sensor depends on the position it is placed on the human body, configuration of the base stations and the propagation phenomenon in the indoor environment in which localisation is taking place. The average accuracy in 3D localisation is around 2 to 3 cm for sensor placed on the elbow and 2.5 to 4 cm for the sensor placed on the chest.","PeriodicalId":22362,"journal":{"name":"The 8th European Conference on Antennas and Propagation (EuCAP 2014)","volume":"82 1","pages":"2097-2099"},"PeriodicalIF":0.0,"publicationDate":"2014-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73057395","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}
