Number: 343/767
Name: Communications: radio wave antennas > Antennas > Slot type
Description: Subject matter including a conducting surface, such as a metallic sheet which may be flat or curved, and an aperture in the surface, which may be completely surrounded by the surface or extended inwardly from an edge of the surface, together with coupling means which establishes a potential difference at spaced points along the aperture or extracts received energy from these points, these points usually being across the aperture, the surface furnishing a conductive path between these spaced points to permit current to flow therebetween.
