Abstract

The invention relates to radio engineering, and can be suitably used for designing small-size antenna devices of diverse applications. The technical result is a significant increase in the antenna effective height and a possibility to provide a directional effect antenna device having the dimensions, in the direction of the predominant propagation of the emitted and absorbed electromagnetic waves, that are much less than quarter of wavelength. Said small-size antenna device comprises an oscillating loop that consists of a reactive element (8) and inductance coil. The reactive element (8) is implemented as a capacitor having a pair of metallic plates (11), the space between said plates being filled with a material (9) containing particles (10) of a conductive substance, which particles are separated by a dielectric filler, the distance between the plates (11) being selected to be less than value lambda /4, where lambda is wavelength of operating signals, the conductive substance being selected such that to satisfy the conditions of ( omega rho <2> epsilon mu /xo) • 10<-11> ≥ 1, (1/ rho omega ) 10 <10> >> epsilon , where omega is frequency of the operating signal; rho is specific conductance of the conductive substance (Ohm • m); epsilon , mu are, respectively, relative electric and magnetic permeabilities of a medium; xo is the least one of dimensions of cross-section of a conductive substance particle, which cross-section is perpendicular to direction of the acting electric field vector. <IMAGE>
