RADIATING SYSTEM OF LINEAR PHASED ARRAY WITH VERTICAL FIELD POLARISATION Russian patent published in 2009 - IPC H01Q1/38 

FIELD: physics.

SUBSTANCE: radiating system of the linear phased array (PA) with vertical field polarisation comprises a radiator rigidly fixed on one of the sides of the angular screen (2), with the angle between the said sides varying from 65° to 135°. On the same side of the angular screen are additionally arranged 2n-1 radiators (1) with the spacing period not exceeding 0.52λ_U. The height of all radiators does not exceed 0.2λ_l, while the wavelength ratio makes λ_l/λ_U≥1.5, where λ_l is the operating frequency lower band wavelength, λ_U is the wavelength of the upper band, n is the number of radiators. Note that n=1, 2, 3, 4.... 2 n radiators of radiating system. Note also that the radiators can represent metal plates furnished with slots or holes.

EFFECT: control over radiation pattern.
