  1. Investigation of a Curtain Antenna Array for TIGER Quang Nguyen, Dr John Devlin Electronics Engineering Dept La Trobe University Australia

  2. Problems of currently used antennas • Structural problem • 1. Broken long elements (wind 47 m/s) • 2. Tower bent along wind direction • 3. Twisted of horizontal boom • Questioning of antenna performance

  3. Objectives • Modification of the Log periodic antenna • to achieve a robust structural that requires • minimal maintenance. • Implementation of frequency independent • array to ensure a broadband operation.

  4. Possibility of compact LPDA

  5. L/Alpha/Bs relationship

  6. A Different Approach

  7. Bs/Tau/N/S1/L relationship

  8. Broaden Structure Bandwidth

  9. Control of electrical height
