ANTENNA Russian patent published in 2021 - IPC H01Q11/10 

FIELD: antenna engineering.
SUBSTANCE: invention relates to antenna engineering, in particular to antenna-feeder devices in the meter range of wavelengths for providing a wide range of radar and radio communication problems for stationary and mobile objects. The technical result is achieved in that in the antenna containing the «wave channel» antenna, which consists of four large passive single symmetric directors arranged on the dielectric bar, active vibration system of six parallel small symmetric vibrators, connected in parallel to the own two-wire collector line, single-wire end-symmetric reflector, unlike the prototype in conjunction with the antenna type «wave channel» a logo-periodic structure consisting of symmetric vibrators fed by its own two-wire distribution line is applied, the length of the shortest symmetrical vibrator of the speech periodical structure is approximately equal to one half of the wavelength of the highest frequency of the working range, and the length of the longest symmetric vibrator of the logo-periodical structure is approximately half the wavelength of the lowest frequency of the working range, with the reflector of the antenna type «wave channel» is structurally integrated with a logothermere structure vibrator, which is additionally mounted on the basis of the geometric length thereof, the geometric length of which is in turn equal to the length of the shortest symmetric vibrator of the logothermere structure, an additional vibrator, a dipole of the lower frequencies, which is arranged in parallel after the longest symmetric vibrator of the logographical structure and is equal to the geometric length thereof, is also mounted.
EFFECT: technical result of the invention consists in increasing several times the number of spare working frequencies in the high-frequency region of the working range, and also in eliminating an unacceptable reduction in the running-wave coefficient in the high-frequency region of the working range.
