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
