The antenna, made of a special material, works as a magnetic emitter and converts vibrations into low-frequency electromagnetic waves between 3 and 30 kHz.
This new device differs from traditional antennas in its versatility. This device, which is 10-15 cm in size, can be used in maritime navigation, communication with submarines and ionospheric research at an altitude of over 100 km above the earth’s surface. This antenna works underwater and underground, unlike antenna towers that work in the air.
Scientists carried out a successful experiment on signal transmission at low frequencies and achieved a transmission range of up to 100 meters. Now they are trying to increase the signal transmission range to increase the efficiency of this portable device.
