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 may be used with a bias component to increase linearity of the system. These tunable elements may modify a radiating element's capacitance or damping rate. Adjusting the shape of the radiating element or using switches may also modify the resonance strength. 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.
