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

摘要： 一种主动偶极天线已被设计用于测量超高能宇宙射线引起的瞬态电场，用于CODALEMA实验。 该探测器的主要要求是包含一个靠近偶极天线的低噪声前置放大器，其带宽范围从100 kHz到100 MHz，并在整个频谱上具有良好的灵敏度。 显示英文摘要

摘要： 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.
