Abstract
An active dipole antenna has been designed to measure transient electric field induced by ultra high energy cosmic rays for the CODALEMA experiment. The main requirements for this detector, composed of a low noise preamplifier placed close to a dipole antenna, are a wide bandwidth ranging from 100 kHz to 100 MHz and a good sensitivity on the whole spectrum.
