MICROSTRIP ANTENNA ARRAY Russian patent published in 2005 - IPC

FIELD: planar-array antennas.

SUBSTANCE: proposed array has two subarrays each incorporating line radiator chain, each radiator being made in the form of three-element filter with side half-wave stubs and quarter-wave microstrip communication lines; central stub is made in the form of radiating component incorporating provision for compensating for its returns by correcting configuration and size of side stubs and quarter-wave communication lines; distance between half-wave radiating components amounts to two thirds of radiated wavelength, and length of microstrip communication lines between them equals radiated wavelength including its shortening in insulating substrate.

EFFECT: facilitated beam shaping by normal to antenna curtain used for building around it phased antenna array scanning in one plane.
