Abstract
An apparatus and method for shielding an operator from electromagnetic fields emitted from an antenna in a portable communication device. A plurality of active shields are placed between the operator's earpiece and the antenna to dampen the effects of the electromagentic fields. The active shields are coupled to adjustment circuits which may include variable gain amplifiers and phase couplers to offset the antenna signal.
