“…The Fig. 9, top, represents a pulse generated by a high energy cosmic ray coming from the zenith, detected by a Butterfly antenna and acquired by an autonomous, self-triggered station [9] of the CODALEMA experiment. This pulse is numerically filtered within a 20-87 MHz band to suppress RFI.…”

“…This is a very preliminary work since this first result is based only on one event, so the shape of induced electric field will have to be investigated with more statistics and more accuracy, for example in order to answer the question whether it is bipolar. Figure 9: Top, an event acquired by the autonomous station [9]. Bottom, the induced electric field generated from the deconvolution of the top curve by the antenna vector transfer function.…”

International audienceAn active dipole antenna is in operation since five years at the Nançay radio Observatory (France) in the CODALEMA experiment. A new version of this active antenna has been developed, whose shape gave its name of "Butterfly" antenna. Compared to the previous version, this new antenna has been designed to be more efficient at low frequencies, which could permit the detection of atmospheric showers at large distances. Despite a size of only 2 m×1 m in each polarization, its sensitivity is excellent in the 30-80 MHz bandwidth. Three antennas in dual polarization were installed on the CODALEMA experiment, and four other have been recently installed on the Auger area in the scope of the AERA project. The main characteristics of the Butterfly antenna are detailed with an emphasis on its key features which make it a good candidate for the low frequency radioastronomy and the radio detection of transients induced by high energy cosmic rays
