LINEAR ANTENNA ARRAY Russian patent published in 2007 - IPC H01Q21/08 

FIELD: antenna engineering.

SUBSTANCE: newly introduced in original strip of N super-broadband longitudinally radiating components spaced d = λ_max/2 apart, operating frequency range of strip being F_l to F_h constituting M octaves, are P = M - 1 strips of super-broadband longitudinally radiating components similar to those of original strip and disposed between longitudinal axes of original-strip extreme components in same plane, with tops uniformly disposed along common line, their high value of boundary frequency F_h being common with that of original strip. Low values F_li of newly introduced strips grow with strip number obeying F_li - 2iF_l law, where i = 1, 2, 3 ...; M -1 is number of introduced strip at initial moment of reading from disposition line of bases of super-broadband longitudinally radiating components of original strip to their top. Quantity of n_i components in newly introduced strips grows with strip number obeying n_i = (N - 1)2^{(i - 1)} law.

EFFECT: enlarged operating frequency range, enhanced gain with frequency increase at same linear dimensions.
