SUMMARY:
These Indian researchers independently confirm the clear advantage to using a fractal design in a
dielectric resonating antenna. The authors note this fractal antenna has a superior performance matrix afforded by both smaller size with dramatically increased bandwidth –50%--using the fractal incorporated design. Gain exceeds 5-6 dBi.
- FRACTAL ADVANTAGE: substantially smaller size with remarkably wide bandwidth; no performance degradation.
- APPLICATION: small device antennas
- FRACTAL DESIGN: Sierpinski
- PATENTS AND PRIORITY DATE: FRACTAL owns the basic patents on fractal element antennas (patents 6,452,553, 7,750,856, and so on), with a patent priority (that is, filing date) of August 1995.
