“…It is however obvious from earlier measurements [3] that the 94 GHz region exhibits much worse propagation properties than the 35 GHz frequency band. The bands at 10 GHz and 35 GHz, however, do not show a big difference.…”

“…Investigations have been reported, which proof, that fire detection with radiometric sensors in the frequency region between 2 GHz to 40 GHz [3] and above [4] is possible. As for the application discussed above a distinctive parameter is the penetration through the leaves of trees a study was initiated to investigate the penetration capabilities at 10 GHz, 35 GHz and 94 GHz.…”

Propagation of electromagnetic waves through canopies of wood are of interest for he choice of operating frequencies for microwave based sensors of different kind. It is known that in general the propagation properties become worse with higher frequency. Especially the upper millimeterwave bands are severely attenuated by leaves. Measurements were conducted during a period in spring on a transmission path through an apple tree. The measurement period covered states of the tree ranging from leave-less over blooming to fully developed leaves on the branches. Three frequency bands were covered, namely 10 GHz, 35 GHz and 94 GHz. To allow a concise judgment of the data, meteorological measurements were done in parallel
