Abstract

A shield for blocking radiation emanating from an antenna within a predetermined radial spectrum. The inventive device includes an arcuate shield positionable along an exterior of an antenna. A securing mechanism is coupled to the shield for securing a position thereof relative to the antenna such that radiation is excluded from a predetermined radial spectrum to protect a head of a user from the radiation.

Claims

1. A communication device antenna shield, comprising:

a shielding means comprising an arcuate exterior body having an arcuate shielding plate concentrically oriented, the arcuate shielding plate extending through an arc of less than about one hundred and eighty degrees around a center of the arcuate exterior body;

a securing means comprising a semi-cylindrical member extending between diametrically opposed longitudinal edges of the shielding means, wherein an antenna can be positioned between the semi-cylindrical body and the arcuate exterior body of the shielding means such that the securing means and the shielding means surround the antenna while blocking less than one hundred and eighty degrees of the radial spectrum of radiation from the antenna; and

a viewing window directed through the arcuate exterior body of the shielding means so as to permit a visual ascertaining of an alignment of the arcuate shielding plate therewithin relative to the antenna.
