Dielectric measurements of tropical wood

Measurement, 2010
The aim of this paper is to determine the dielectric characteristics of tropical wood species at microwaves frequency in order to use them as planar antenna substrate. The measurements have been done on dried wood in the frequency range 8.2-12.4 GHz The suitability of wood as a microwave printed antenna substrate will be determined by the values taken ...
