RADIO COMMUNICATION SYSTEM Russian patent published in 1998 - IPC

FIELD: radio engineering, radio communication systems between control posts located in medium with losses, provision for communication between underground objects. SUBSTANCE: proposed system incorporates: at transmitting communication post- radio transmitter and at receiving communication post-radio receiver connected to antennas placed into medium with losses. Each communication post has source of bias field which outputs are connected to bias electrodes 8, 9 placed into medium with losses and insulated from it by dielectric shells. Bias electrodes can be additionally connected trough filters to inputs of antenna insulated from medium. Power increase is achieved in radio communication system thanks to decrease of losses in medium located immediately above antenna and thanks to enhanced efficiency of antenna owing to change of macroscopic parameters of local extent of medium bordering on points of installation of antenna. EFFECT: increased power of radio channel while communicating between posts positioned in medium with losses. 4 cl, 9 dwg
