Abstract

As a result of extremely strong couplings, the element patterns of antennas in wideband phased arrays strongly depend on their position within the array. The differences with respect to the infinite-array solution are analyzed for dual-polarized arrays made of tapered-slot antennas. Exploiting the three symmetry planes of the arrays, MoM solutions are obtained for arrays containing up to 9×10×2 elements. The effects of array truncation are stronger for low frequencies and grazing angles. The phenomenon of waveguide anomaly is analyzed in finite arrays versus frequency and scan angle.
