Design of a low noise, wide band, active dipole antenna for a cosmic ray radiodetection experiment

摘要

An active dipole antenna has been designed to measure transient electricfield induced by ultra high energy cosmic rays for the CODALEMA experiment. Themain requirements for this detector, composed of a low noise preamplifierplaced close to a dipole antenna, are a wide bandwidth ranging from 100 kHz to100 MHz and a good sensitivity on the whole spectrum.
