CIRCULAR-POLARIZATION MICROSTRIP ANTENNA Russian patent published in 2005 - IPC

FIELD: antenna engineering.

SUBSTANCE: proposed antenna that can be used in production of various receiving, transmitting, and transceiving antenna assemblies including phased antenna arrays has microstrip line with exciting structure on one end and ground conductor, on other that has slots functioning as radiators; these relatively perpendicular slots are disposed on adjacent sides of square radiator each of whose sides equals half-wavelength; radiator is coupled with slots through first and second insulating layers; dielectric constant of second insulating layer is twice as high as that of first insulating layer; slots are series-excited by means of one section of microstrip line.

EFFECT: enhanced efficiency.
