Wide-band fractal antenna
View Patent ↗An apparatus includes a discone antenna including a cone-shaped element whose physical shape is at least partially defined by at least one pleat.
1. An apparatus comprising:
a discone antenna including a cone-shaped element, the physical shape of which is at least partially defined by at least one pleat, wherein each pleat includes two faces joined at a vertex having an included angle of less than 180 degrees as directed away from a principal axis of the cone-shaped element, and wherein the two faces of the pleat do not substantially overlap one another in a direction transverse to a bisector of the included angle.
2. The apparatus of claim 1 wherein the discone antenna includes a disc-shaped element whose physical shape is at least partially defined by a fractal geometry.
3. The apparatus of claim 1 wherein the physical shape of the cone-shaped element includes a least one hole.
4. The apparatus of claim 1 wherein the physical shape of the cone-shaped element is at least partially defined by a series of pleats that extend about a portion of the cone.
5. An apparatus comprising:
a bicone antenna including two cone-shaped elements, the physical shape of at least one of which is at least partially defined by at least one pleat, wherein each pleat includes two faces joined at a vertex having an included angle of less than 180 degrees as directed away from a principal axis of the cone-shaped element, and wherein the two faces of the pleat do not substantially overlap one another in a direction transverse to a bisector of the included angle.
6. The apparatus of claim 5 wherein the physical shape of one of the two cone-shaped elements is at least partially defined by at least one hole.
7. The apparatus of claim 5 wherein the physical shape of one of the two cone-shaped elements is at least partially defined by a series of pleats that extend about a portion of the cone.
