Foliage is modeled in the radiative transfer equation as a medium of random scatterers. However, other phenomena in the wireless channel may also occur. In this work, vegetation attenuation measurements are presented for a single tree alley for 26\u201332 GHz. The results show that vegetation loss increases significantly after the second tree in the alley. Measurement-based foliage losses are compared with model-based, and new tuning parameters are proposed for models.<\/jats:p>","DOI":"10.3390\/s24103190","type":"journal-article","created":{"date-parts":[[2024,5,17]],"date-time":"2024-05-17T06:53:49Z","timestamp":1715928829000},"page":"3190","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Vegetation Loss Measurements for Single Alley Trees in Millimeter-Wave Bands"],"prefix":"10.3390","volume":"24","author":[{"given":"Krzysztof","family":"Cicho\u0144","sequence":"first","affiliation":[{"name":"Institute of Radiocommunications, Poznan University of Technology, 60-965 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maciej","family":"Nikiforuk","sequence":"additional","affiliation":[{"name":"Tietoevry, al.
