Dipole antenna with a modified fractal structure

摘要

The utility model refers to an antenna technique and can be used as an element for creating phased antenna arrays in conditions of limited placement conditions, for example, on moving objects. The dipole antenna with a modified fractal structure has two arms in the form of Sierpinski triangles, where the initial arm is formed from an isosceles triangle with a height h and a basea, in which triangular notches are made in the form of a Sierpinski fractal with the vertices of triangles indicated by , , , a₁= 1 for a fractal of the 1st iteration, , , , a₁= 1, a₂= 1; 2; 3 for the second iteration fractal;, , , a₁= 1, a₂= 1; 2; 3,a₃= 1; 2; 3 for the third iteration,, , , a₁= 1, a₂= 1; 2; 3,a₃= 1; 2; 3, ...,a_n= 1; 2; 3 for the nth iteration fractal, the sides, , ..., are parallel to the base a. At the same time, at each vertex of the Sierpinski fractal, , ..., the electrical contact is broken, and the symmetrical arm is obtained by rotating the initial arm by 180 ° relative to the axis passing through the vertex of the original isosceles triangle opposite the base a and perpendicular to the plane of the original arm. The technical result consists in reducing the resonant frequency of the antenna, which ensures its operation both in the reception mode and in the transmission mode. 10 yl.
