Abstract
The omnidirectional multiband antenna is a variant on a monocone antenna, particularly including a corrugated extending surface for lowering the low frequency cutoff of the monocone antenna. The omnidirectional multiband antenna includes an electrically conductive conical surface, having a vertex end and a base end, and at least one electrically conductive annular member mounted on the base end. The at least one electrically conductive annular member is formed from a plurality of stacked segments and has a corrugated exterior surface. The vertex end of the electrically conductive conical surface is positioned adjacent to, and spaced apart from, a first surface of a ground plane plate. A plurality of cylindrical rods is provided, a first end of each rod being secured to the at least one electrically conductive annular member, and a second end of each rod being mounted on the first surface of the ground plane plate.
