RFID systems in the UHF frequency band offer reading distances of tens of centimetres, allowing the localisation and identification of the queen bee inside the hive. With this purpose, this work proposes an analysis of an environment of propagation that consists of a honeycomb frame, where the reader is placed within the frame, and the tag is placed in different positions over it. A honeycomb frame consists of a wooden box containing a honey wax panel, supported by metallic wires. The environment is modelled theoretically using its S-parameters and simulated in CST Studio. An analysis of these results and empirical measurements is performed. The results show that a periodicity in the received power of the tag is found with respect to the distance to the reader when the tag is located in a direction parallel to the wire, where local maximum and minimum values are found. Additionally, when the tag is placed over a wire of the frame, a higher received power is obtained compared to the case where the tag is placed between two wires. Furthermore, it has been observed that the reading range has increased with respect to free space, covering the full frame.<\/jats:p>","DOI":"10.3390\/s24113356","type":"journal-article","created":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T11:37:13Z","timestamp":1716464233000},"page":"3356","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Propagation Analysis of an RFID System in the UHF Band in the Honeycomb Frame of a Beehive"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-0595-6596","authenticated-orcid":false,"given":"Jos\u00e9","family":"Lorenzo-L\u00f3pez","sequence":"first","affiliation":[{"name":"Department of Information and Communications Technology, Polytechnic University of Cartagena, 30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1046-3466","authenticated-orcid":false,"given":"Leandro","family":"Juan-Ll\u00e1cer","sequence":"additional","affiliation":[{"name":"Department of Information and Communications Technology, Polytechnic University of Cartagena, 30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"62","DOI":"10.17660\/ActaHortic.1991.288.4","article-title":"The value of honeybee pollination to society","volume":"228","author":"Gill","year":"1991","journal-title":"Acta Hortic."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"260","DOI":"10.17660\/ActaHortic.1991.288.39","article-title":"The importance of honeybee-pollination for the quality and quantity of strawberries","volume":"228","author":"Svensson","year":"1991","journal-title":"Acta Hortic."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1126\/science.1146498","article-title":"A metagenomic survey of microbes in honeybee colony collapse disorder","volume":"318","author":"Conlan","year":"2007","journal-title":"Science"},{"key":"ref_4","unstructured":"(2020, March 10).
