Abstract:
An antenna system may include a first metamaterial antenna having a first resonant frequency and a second metamaterial antenna having a second resonant frequency. The first resonant frequency may be different from the second resonant frequency. A first feed point may be connected to the first metamaterial antenna, and a second feed point may be connected to the second metamaterial antenna. A signal may be applied to the first and second feed points so that the first and second metamaterial antennas radiates electromagnetic energy while the signal is being applied and so that the antenna system is configured to send or receive signals over both the first and second resonant frequency bands.
