Abstract
An antenna for a communications device with a design to minimize human exposure to emitted electromagnetic energy. The antenna incorporates a shield wall and directing buds having the property of reflecting, deflecting or absorbing RF frequency waves. The shield wall and directing buds direct transmitted communication signals away from the immediate user and other bystanders in the vicinity of the communications device while simultaneously directing a stronger signal towards a receiver. Alternative embodiments of the antenna include the ability to extend or swivel. These features allow the antenna to be positioned to maximize transmission/reception while simultaneously minimizing human exposure.
