ABSTRACT:
Systems and methods for a dual-band antenna and methods for manufacturing the same are described. One system and method includes a plurality of antenna elements. Groups of the antenna elements cooperate to form directional antennas at various frequencies. Using an active element, configurable at different frequencies and reflectors tuned to different frequencies, directed transmission or direction of positive gain for the antenna system is achieved. The system can be used for various wireless communication protocols and at various frequency ranges.
