ANTENNA CORE AND ANTENNA Russian patent published in 2011 - IPC H01Q7/08 H01F1/26 

FIELD: radio engineering.

SUBSTANCE: antenna core is made by formation of soft magnetic metal powder by using resin as binding agent. At that, soft magnetic metal powder is amorphous soft magnetic metal powder corresponding to common formula (1): (Fe_1-x-yCo_xNi_y)_100-a-b-cSi_aB_bM_c (1), and resin used as binding agent represents thermoreactive resin. M represents at least one element chosen from the group consisting of Nb, Mo, Zr, W, Ta, Hf, Ti, V, Cr, Mn, Y, Pd, Ru, Ga, Ge, C, P, Al, Cu, Au, Ag, Sn and Sb. Each of x and y represents atomic ratio, and each of a, b and c represents percentage atomic ratio meeting the following relations: 0≤x≤1.0, 0≤y≤0.5, 0≤x+y≤1.0, 0≤a≤24, 1≤b≤30, 0≤c≤30 and 2≤a+b≤30. Soft magnetic amorphous metal powder forms crystallites of nanocrystals, the size of which does not exceed 100 n.m.

EFFECT: increasing elasticity modulus of antenna core, its stability at increased temperatures.
