Abstract

In one example embodiment, a magnetic shutter antenna is provided including at least one dipole magnet comprising a first end and a second end and 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. The antenna further includes a motor coupled to the shutter and 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. Alternation 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.
