54099465 antenna

  1. 2. Over view <ul><li>Introduction </li></ul><ul><li>Need of fractal antenna </li></ul><ul><li>History </li></ul><ul><li>Features </li></ul><ul><li>Examples </li></ul><ul><li>Creation </li></ul><ul><li>Applications </li></ul>
  2. 3. Antenna <ul><li>A transducer that send and receive Em waves </li></ul><ul><li>Covert Em radiations to electric current or vice versa </li></ul><ul><li>Used in broadcasting, point to point communication, cell phones space craft communication </li></ul>
  3. 4. Fractal <ul><li>Benoit Mandelbrot 1975 Latin fractus – broken or fractured </li></ul><ul><li>Geometric shape that can be split into parts each of which is reduced size copy of the whole </li></ul>
  4. 5. Fractal Antenna <ul><li>Antenna that self-similar design to maximize the length, or increase the perimeter of material that can receive or transmit electromagnetic radiation within a given total surface area or volume. </li></ul><ul><li>Multi level space filling curves </li></ul><ul><li>Iterations </li></ul><ul><li>A good example of a fractal antenna as a space filling curve </li></ul>
  5. 6. Why Fractal Antenna <ul><li>Compact </li></ul><ul><li>Wide band application </li></ul>
  6. 7. History <ul><li>Euclidean geometry </li></ul><ul><li>Area directly proportional to perimeter </li></ul><ul><li>Emphasis on frequency resonance and power patterns </li></ul><ul><li>First order iteration </li></ul><ul><li>No attempts to exploit multiple scale self similarity or real fractals </li></ul>
  7. 8. Equations <ul><li>Fractal ratio limit direction D=logL/logr </li></ul><ul><li>Premature compression parameter </li></ul><ul><li>Pc= full size antenna element length </li></ul><ul><li>Pc=A log [N(C+D)] </li></ul>
  8. 9. Area of creation <ul><li>Adding the reflector </li></ul><ul><li>Drill holes and add mounting points </li></ul><ul><li>Measure, cut, and strip wire </li></ul><ul><li>Create fractals </li></ul><ul><li>Create dipoles </li></ul><ul><li>Mount dipoles and mount transformer </li></ul><ul><li>Testing verses store bought antenna </li></ul>
