Abstract
This paper presents the application of a genetic algorithm (GA) to adapt an antenna array´s response in order to reject interference. Since the GA reduces the total power output of the array, constraints are used to prevent nulling of the desired signal received by the main beam. Constraints take the form of using only the least significant bits or a subset of the elements to perform the nulling. Examples demonstrate adaptive nulling using amplitude and phase, phase only, and amplitude only weights
