MICROSTRIP FEEDING LINE Russian patent published in 2009 - IPC H01P5/02 H01P3/08 

FIELD: physics; radio.

SUBSTANCE: invention concerns electro-radio engineering area, in particular, to the antenna-feeding technique and can be used in equipment of communication and microwave devices and arrangements. The essence of the invention: the microstrip feeding line contains a dielectric substrate with a current-carrying conductor in the form of a zigzag-line executed on one side, and the metal screen with, at least, two longitudinal slots executed on the other side; width of the slots does not exceed width of conductors of the screen. According to the invention, distinctive feature of a microstrip feeding line is that it is supplied with, at least, two jumpers located against each other on distance, at least, of the one sixth length of the slow wave and connecting serially central and peripheral next conductors of the screen accordingly.

EFFECT: feeding line with an abnormal dispersion and distribution of electromagnetic waves with a phase velocity increasing with growth of fluctuations frequency.
