Magnetic shutter antenna

A magnetic shutter antenna comprising:

• at least one dipole magnet comprising a first end and a second end;
• a first shutter of magnetically soft material comprising at least one opening and disposed proximate the first end of the at least one dipole magnet;
• a second shutter of magnetically soft material comprising at least one opening and disposed proximate the second end of the at least one dipole magnet;
• and
• at least one motor coupled to the first and second shutters, the at least one motor configured to move the first and second shutters between a first closed position comprising the magnetic material of the first and second shutters being positioned adjacent the first and second ends of the at least one dipole magnet and a second open configuration comprising the openings of the first and second shutters being positioned adjacent the first and second end of the at least one dipole magnet,
• wherein alternation between the first closed position and the second open position modulates a magnetic flux emitting from the first and second ends of the at least one dipole magnet.

A method of transmitting a signal with an antenna, the method comprising:

• providing a magnetic shutter antenna comprising:
• at least one dipole magnet comprising a first end and a second end;
• at least one shutter of magnetically soft material comprising at least one opening and disposed proximate the first end of the at least one dipole magnet;
• and
• a motor coupled to the shutter, the motor configured to move the shutter between a first closed position comprising the magnetic material being positioned adjacent the first end of the dipole magnet and a second open configuration comprising the opening being positioned adjacent the first end of the dipole magnet,
• controlling the motor to alternate the at least one shutter between the first closed position and the second open position modulates a magnetic flux emitting from the first end of the at least one dipole magnet.
