Abstract

An apparatus includes a discone antenna including a cone-shaped element whose physical shape is at least partially defined by at least one pleat.

Claims

1. An apparatus comprising:

an antenna including a flat disc-shaped element including a conductive pattern disposed on a surface of the disc-shaped element, wherein the physical shape of the conductive pattern is at least partially defined by a fractal geometry and that is configured and arranged to receive and transmit electromagnetic radiation; and

a conical portion connected to the flat-shaped disc element.

2. The apparatus of claim 1 wherein the physical shape of the disc-shaped element is at least partially defined by a hole.
