Non-stationary parameters (direction to the sources of oscillations, their intensities and localization) have been studied and estimated. The wave field distribution in elastic solid medium is recorded by the array of strain sensitive units. Every strain detector represents the laser interferometer with base-length 1–400 m, which measures the distant difference between two points of the solid medium. In this way spatial and temporal distribution of a strains field is being evaluated. The output signals of every laser sensors supplies the consequent inputs of multi-channel analog-to-digital converter and the obtained data are stored and subjected to the processing in the PC. The procedure of numerical treatment is based on the Fourier spectral analysis, which results to the tracks of non-stationary source motions to be displayed. The examples of described procedure for laser interferometers being apart up to 140 km and obtained data are presented.","PeriodicalId":433613,"journal":{"name":"2011 VIII International Conference on Antenna Theory and Techniques","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122776647","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 paper by Lucien Poincaré contained information that Marconi was the author of radio engineering's term \"antenna”.

Main topic is focused on the hardware supporting European standard that assumes the use of the total UWB frequency band with 5GHz band (4.8–6.3 GHz) cut-off. Typical realization of the front-end part uses single full-band antenna, bandpass filter (BPF) and bandstop filter (BSF). The antenna with the BPF provide frequency selection of total UWB band (3.1–10.6 GHz), while the BSF cuts off the unwanted frequency band at 5 GHz. A solution proposed in this paper is alternative to the typical one. The idea is based on double antenna architecture, where each of the antennas covers correspondent frequency band (low and high bands). Signals from the antennas are combined together either with power combiner or diplexer/duplexer. An analysis and a comparison have been made with these types of the combiners.","PeriodicalId":433613,"journal":{"name":"2011 VIII International Conference on Antenna Theory and Techniques","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123752132","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}
