LOW-PROFILE VERTICALLY-POLARIZED OMNI ANTENNA

摘要

An omni-directional antenna including a plurality of stacked omni-directional antenna core assemblies. Each antenna core assembly comprises a conductive ground plane defining an axis normal to the ground plane and a plurality of conductive plates projecting orthogonally from the conductive ground plane and angularly spaced about the axis. Each of the plates defines an edge extending radially outboard from the central axis and diverging away from the conductive ground plane as the radial distance increases from the central axis. The edge defines a first region defining an acute angle relative to the conductive ground plane and a second region, radially outboard of the first region defining an arcuate shape.
