dimension>
D (wire diameter) : 0.6 mm Rh0 (helix 0 radius) : 12 mm
Hh0 (helix 0 height) : 24 mm Rh1 (helix 1 radius) : 12.9 mm
Hh1 (helix 1 height) : 25.8 mm
N (number of turns) : 0.4
Material>
wire from copper 0.6 mm
nah, saya bingung di realisasinya.. udah saya buat prototype sih, freq masih geser disekitaran 2.1, 2.3, 2.5 GHz soalnya bener2 handmade jadi ga kokoh.. (gambar nyusul deh)
temen2 sekalian ada yang tau dimana yang bisa manufactur antenna gituan??
terimakasih sangat.. mohon2
