ULTRA BROADBAND ANTENNA RANGE DMV2 Russian patent published in 2018 - IPC H01Q9/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering, namely to broadband antennas of transceiver devices. Device contains two dipoles. Each of the dipoles is made of two radiating elements installed with a gap between them, which are electrically connected via a feeder line. Each of the radiating elements of the dipole is made in the form of the lower glass – inverted, and the upper glass, facing its bottom to the bottom of the lower glass. Each of the glasses is stepped, and the steps of smaller diameter are facing each other. Feeder line is made of three lengths of coaxial cable. First segment of the coaxial cable is selected with a characteristic impedance of 50 Ohms, and the second and third segments of the coaxial cable are selected with a characteristic impedance of 100 Ohms. First segment of the coaxial cable is passed along the longitudinal axis of the first dipole inside the glasses through their bottoms into the gap between the dipoles, its central core is connected with interconnected central cores of the second and third segments of the coaxial cable, and its braid with their braids. Second segment of the coaxial cable is passed along the longitudinal axis of the first dipole inside the upper glass through its bottom into the gap between the upper and lower glasses, its central core is connected to the bottom of the upper glass and the braid to the bottom of the lower glass. Third segment of the coaxial cable is passed along the longitudinal axis of the second dipole inside the bottom glass through its bottom into the gap between the upper and lower glasses, its central core is connected to the bottom of the upper glass and the braid to the bottom of the lower glass.

EFFECT: technical result consists in providing a radiation pattern without crushing the main lobe, reducing the SWR, reducing the longitudinal dimensions and simplifying the design.
