Active wideband antenna for underwater tomography (1 GHz)
Résumé
A new active antenna has been designed to measure electromagnetic fields in water. It combines a differential wideband amplifier and a dipole, the characteristics of which have been designed to provide a constant gain on the bandwidth of the antenna. The small size of the dipole reduces the mask effect. The designed antenna is a symmetrical reception antenna for the electromagnetic field measurement in water in the frequency range of 100 MHz to 1 GHz and it introduces few disturbances. A possible application will be the microwave imaging of immersed objects.
