AIRCRAFT ANTENNA NOZZLE Russian patent published in 2019 - IPC H01P1/26 

FIELD: antenna equipment.

SUBSTANCE: invention relates to radio engineering and specifically to antenna engineering and antenna measurement techniques. Aircraft antenna nozzle comprises a coaxial connector shielding the housing, inside of which there is a conducting bushing installed by means of an insulator coaxially to the screening housing, and a communication element electrically connected to the coaxial connector, according to invention shielding housing is open at one end, insulator and sleeve are arranged under communication element installed perpendicular to axis of nozzle and made in form of printed circuit board with two conductors located in one plane and bent at angle of 90° with formation of pairwise equal short and long sections, length and width of which are selected so that difference of current phases in them is 90°, wherein the bend of one conductor is connected to the central conductor of the coaxial connector, the longitudinal axis of which is parallel to the axis of the housing, and the bend of the other conductor – with the bushing, in which along the direction to the coaxial connector a cut is made for performing current balancing, wherein the coaxial connector is installed coaxially nozzle.

EFFECT: maintaining aircraft antenna matching characteristic when performing checks for reliable evaluation of radio communication equipment operability, providing protection against unauthorized signal reception.
