Claims
- 1. A method for producing a magnetic alternating field for transmission of information units of an antenna array to a portable receiving module, which is freely movable in the magnetic alternating field, comprising the step of:supplying information units to frame antennas of an antenna array, said frame antennas comprising at least one winding whereby tiers defined by said antenna arrays are pair-wise but not plane-parallel, said information units are sequentially alternated between said frame antennas by via on/off modulation whereby a quasi-isotropic magnetic field is radiated from said antenna array.
- 2. The method according to claim 1, further comprising the step of:placing at least one of said frame antennas on a receiving module such that an induction for the reception of an information unit occurs on said at least one of said frame antennas.
- 3. The method according to claim 1, wherein said tiers defined by said frame antennas are essentially orthogonally adjustable towards each other and said frame antennas are interlaced.
- 4. The method according to claim 1, further comprising the steps of:connecting several antenna arrays to a coaxial cable; arranging said arrays so as to comprise cascading arrays; and producing a quasi-isotropic magnetic alternating field by a wiring which takes into account an opposite position of said antenna array.
- 5. The method according to claim 4, wherein said cascading arranged antenna arrays are constructively identical but that two sequential antenna arrays are positioned and turned by pi.
- 6. The method according to claim 5, further comprising the steps of:generating an information unit by a connected oscillator and modulator, and supplying said information unit to said coaxial cable.
- 7. The method according to claim 1, wherein said frame antennas comprise three frame antennas.
- 8. The method according to claim 1, wherein said tiers defined by said frame antennas are essentially orthogonally adjustable towards each other or said frame antennas are interlaced.
- 9. The method according to claim 1, further comprising the steps of:connecting several antenna arrays to a coaxial cable; arranging said arrays so as to comprise cascading arrays; and producing a quasi-isotropic magnetic alternating field by a geometrical positioning of individual antenna arrays.
- 10. The method according to claim 9, wherein said cascading arranged antenna arrays are constructively identical but that two sequential antenna arrays are positioned and turned by pi.
- 11. The method according to claim 10, further comprising the steps of:generating an information unit by a connected oscillator and modulator, and supplying said information unit to said coaxial cable.
