The Axial Ratio of Planar Arrays with Random Element Errors
By
Progress In Electromagnetics Research Letters, Vol. 87, 1-6, 2019
Abstract
Characterizing the random errors at the elements of a phased array antenna leads to equations that estimate the associated performance degradation. The increase in sidelobe level and decrease in gain due to random errors is well established. This paper derives an expression that predicts the axial ratio degradation due to random errors in the circularly polarized elements of an array. In the case of small errors in an array of crossed dipoles, we found a simple expression for the axial ratio of the array under random errors at broadside.
