METHOD FOR INCREASING EFFECTIVE HEIGHT OF SMALL- SIZE ANTENNA ASSEMBLY AND SMALL-SIZE ANTENNA ASSEMBLY FOR IMPLEMENTING THIS METHOD Russian patent published in 2002 - IPC

FIELD: radio engineering; miscellaneous small-size antenna assemblies. SUBSTANCE: small-size antenna assembly has oscillatory circuit set up of reactance unit and inductance coil. Reactance unit is made in the form of capacitor with pair of metal plates, space between them being filled with material containing conducting substance particles separated by insulating filler; distance between plates is chosen to be smaller than λ/4, where λ is wavelength of effective signals; conducting substance is chosen proceeding from conditions (ωρ²εμ/x_o)•10^-11≥1,(1/ρω)10¹⁰≫ε, where ω is effective signal frequency; ρ is resistivity of conducting substance, ohm-m; ε, μ is, respectively, relative dielectric constant and magnetic permeability of conducting substance; x₀- is the least of cross-sectional areas of conducting substance particle perpendicular to effective electric field vector. Dimensions of this directional antenna assembly in direction of primary propagation of radiated and absorbed electromagnetic waves is much smaller than quarter-wavelength. EFFECT: enhanced effective height of antenna. 13 cl, 7 dwg
