The proposed device permits the evaluation of the cross-talk effect that, in conventional exposimeters, generates a mistake estimation of electromagnetic fields. The device was calibrated in an anechoic chamber for far-fields and was validated against a portable spectrum analyzer in a residential area. A strong correlation between the two devices with a confidence higher than 95% was obtained; indicating that the device could be considered as an important tool for electromagnetic field studies.<\/jats:p>","DOI":"10.3390\/s21217395","type":"journal-article","created":{"date-parts":[[2021,11,7]],"date-time":"2021-11-07T20:42:54Z","timestamp":1636317774000},"page":"7395","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Compact Exposimeter Device for the Characterization and Recording of Electromagnetic Fields from 78 MHz to 6 GHz with Several Narrow Bands (300 kHz)"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5996-1442","authenticated-orcid":false,"given":"Marco","family":"Rivera Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Center for Biomedical Technology (CTB), Escuela Tecnica Superior de Ingenieros de Telecomunicaciones (ETSIT), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4433-3707","authenticated-orcid":false,"given":"Nazario","family":"F\u00e9lix Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Center for Biomedical Technology (CTB), Escuela Tecnica Superior de Ingenieros de Telecomunicaciones (ETSIT), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9551-2241","authenticated-orcid":false,"given":"Isabel","family":"L\u00f3pez","sequence":"additional","affiliation":[{"name":"Center for Biomedical Technology (CTB), Escuela Tecnica Superior de Ingenieros de Telecomunicaciones (ETSIT), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Ochoa Zambrano","sequence":"additional","affiliation":[{"name":"School of Computer Systems Engineering (ETSISI), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8725-5089","authenticated-orcid":false,"given":"Andr\u00e9s","family":"Miranda Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Center for Biomedical Technology (CTB), Escuela Tecnica Superior de Ingenieros de Telecomunicaciones (ETSIT), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ceferino","family":"Maest\u00fa Unturbe","sequence":"additional","affiliation":[{"name":"Center for Biomedical Technology (CTB), Escuela Tecnica Superior de Ingenieros de Telecomunicaciones (ETSIT), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"},{"name":"Networking Research Center of Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN), Universidad Polit\u00e9cnica de Madrid (UPM), 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,7]]},"reference":[{"key":"ref_1","unstructured":"ITU (2021, January 21).
