Nonlinear distortion reduction in active arrays taking advantage of their spatial power-combining properties

In this article, a linearity‐improving technique for active antennas and arrays, based on spatial power combining, is presented. An auxiliary branch is employed to cancel the radiation pattern at the intermodulation distortion (IMD) components, either in the main‐beam direction for a subarray or in...
