Abstract

This paper contributes the dielectric properties
measurements on five mixture of biocomposite antenna substrates
in water immersion condition. The fabrications process of the
biocomposite antenna substrate uses the compounding flat press
method between the Polypropylene acting as laminator and stem
three of Leucaena Leucocephala as a filler. The dielectric
properties measurements conducted by using the KEYSIGHT
85070E coaxial probe method, with the observe frequency range
of 1 GHz to 20 GHz and ASTM D570 procedure for water
immersion process. The percentages of the water absorption rate
reported 0.026 % (PP100), 0.18 % (PB9010), 0.22 % (PB8020),
0.28% (PB7030) and 0.35 (PB6040), while the changes of the
dielectric properties reported increase 10.31 % (PP100), 11.16 %
(PB9010), 15.48 % (PB8020), 23.60 % (PB7030) and 36.35 %
(PB6040) when compared with the dielectric properties
measurements before 24 Hours ASTM D570 water immersion
procedure. The changes of the water absorption rate and dielectric
properties percentages in line with the increments of filler
composition mixture. The data from this measurement useful to
observe the aging shielding capability of the material against water
and moisture content absorption for antenna substrate material.
