Resonance and non-resonance forms of near-field magnetic communication system transmitters are investigated. The transmitters can be used for magnetic communications when widespread electromagnetic communication systems are not effective. For example, it is useful for transmitting data between underground or underwater objects; for communications with objects in reinforced concrete constructions, in basements and in other cases. Resonance and non-resonance constructions of transmitter are discussed with direct connection between power amplifier and transmitting loop and with connection trough a transformer. Advantages and disadvantages of presented transmitter forms are shown with recommendations for practical application.
