Abstract
The present disclosure provides a system and methods for mitigating, or reducing, the intermodulation of an adaptive antenna array's radiating elements. A tunable element or tunable material, such as a phase change material or a state change material, may be used to increase linearity of the RF transmission properties. These phase or state change materials may modify a radiating element's electromagnetic response. In some embodiments, variable couplers may further be added to a system to reduce intermodulation. An adaptive antenna array using the techniques described herein may have all or some of the elements co-located.
