  • Dual-band very low frequency antenna
    Patent number: 11784399
    Abstract: Disclosed is a dual-band very low frequency antenna, which comprises positive and negative electrodes, silicon substrates, piezoelectric material units, stress-electromagnetic conversion material units and an insulator. The piezoelectric material units are arranged between the positive and negative electrodes; the stress-electromagnetic conversion material units and the silicon substrates are respectively arranged at both ends of the positive and negative electrodes. The positive and negative electrodes are used for driving the piezoelectric material units; the piezoelectric material units are used for generating flutter and conducting the flutter to the stress-electromagnetic conversion material units; the stress-electromagnetic conversion material units are used for converting vibration waves generated by flutter into electromagnetic wave radiation.
    Type: Grant
