成果简介	NOVELTY - The antenna has a dielectric substrate (1), a shielding layer, a coaxial feed line, and a radiating conductive pattern. The substrate is made in the form of a 1 mm thick FR-4 foil-clad fiberglass containing a radiating conductive pattern on both sides. The radiating conductive pattern of the upper layer is one Bow-Tie lobe with an elliptical rounding at the end and with a microstrip line of constant length, which is connected to central core of the coaxial transmission line. The radiating conductive pattern of lower layer is a mirror image of the radiating conductive pattern of the upper layer with a matching line (4) with an exponential transition, which is connected to the screen of the coaxial line. USE - Compact broadband bow-tie antenna for communication system with unmanned aerial vehicle of ground and air basing, and interference-resistant communication system. ADVANTAGE - The dynamic range and the use of the exponential matching line are expanded to significantly expand the frequency range, because the matching of the compact broadband bow-tie antenna with the source of electromagnetic waves is increased, while ensuring a small antenna profile which is especially important when used on highly mobile platforms-unmanned aerial vehicle (UAV). The antenna pattern consisting of two layers is applied to a two-layer rectangular foil dielectric, while the main lobes of the bow-tie antenna have roundings to align the fronts and trajectories of currents, and the use of an exponential transition ensures an increase in the matching of resistances, which ensures an expansion of the operating frequency range and an increase in the efficiency of the antenna. The use of the matching line with exponential transition allows for a smooth change in resistance, which leads to an expansion of the antenna operating frequency range, in addition, the alignment of current fronts is ensured by adding elliptical roundings on the conducting patterns of the upper and lower layers. The operating frequency range is expanded, as well as two additional operating ranges are formed due to the use of the matching line. The expansion of the dynamic range due to the use of a broadband exponential matching line is realized, the use of a substrate in the form of thin foil-clad fiberglass Fr-4 allows to reduce the antenna profile, which is especially important for highly mobile aerodynamic purposes, such as UAVs. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the antenna device based on printed double-sided dielectric with a wide range of operating frequencies based on bow-tie emitter. 1Dielectric substrate 2Top layer 3Bottom layer 4Matching line with exponential transition
