Variable position antenna shield

A variable position antenna shield (VPAS) is described that provides a mechanism for attenuating radio interference signals and other electromagnetic waves using a movable shield. The VPAS contains an antenna assembly, an antenna, and a patch variably positioned exterior to the antenna, wherein the patch attenuates passage of electromagnetic radiation such that the passage of electromagnetic radiation through the patch is substantially blocked, the patch being variably positioned to affect the directivity pattern of the antenna.
