Abstract
Antenna system comprising at least two radiating elements, a first line for neutralizing electromagnetic coupling between the at least two radiating elements, at least one radiofrequency power supply line for each radiating element and at least one short-circuiting line to a ground plane of the antenna system per radiating element, characterized in that the antenna system further comprises: at least one second line for neutralizing electromagnetic coupling between said at least two radiating elements; elements for activating at least some of the neutralization lines; and in that the activation elements are configured to selectively activate or deactivate at least some of the neutralization lines, in such a way that depending on the activation/deactivation thereof the neutralization lines provide a maximum neutralization of the electromagnetic coupling of the radiating elements for a plurality of different frequencies.
