Adaptive antennas are advanced communication devices that can automatically adjust their radiation patterns to improve signal quality. They use algorithms to analyze incoming signals and determine the best way to focus on desired signals while minimizing interference from unwanted sources. This capability enhances the performance of wireless systems, such as cellular networks and Wi-Fi. These antennas are particularly useful in environments with multiple users or obstacles, as they can dynamically adapt to changing conditions. By optimizing the direction and strength of the signal, adaptive antennas help maintain reliable connections and increase overall network efficiency, benefiting technologies like 5G and satellite communications.
