Class Information
Number: 343/841
Name: Communications: radio wave antennas > Antennas > With electrical shield
Description: Subject matter wherein a conductive or low reluctance structure, such as a wire, plate, or grid, is combined with the antenna to reduce, as by dissipation through a resistance or by conduction to ground, undesired radiation, or electric or magnetic fields, which are directed toward the antenna from an external source, or which emanate from the antenna.
