Abstract
Antenna system composed of (N+1) virtually identical radiating structures with N greater than or equal to 1, said (N+1) structures being arranged parallel to each other and each radiating structure being connected to a power supply and impedance matching device. Use for frequency ranges between 1.5 to 30 MHz.

An antenna system composed of (N+1) virtually identical radiating structures with N greater than or equal to 1, said (N+1) structures arranged parallel to each other, each radiating structure is connected to a power supply and impedance matching device wherein it comprises at least a processor equipped with control logic Cm adapted to tune the “master” radiating structure and vary at least one of the tuning parameters so that they converge towards the values leading to tuning and logic Cs for transferring the parameters corresponding to the tuning of the “master” radiating structure to the “slave” radiating structure(s).
A method to tune an antenna system comprising (N+1) virtually identical radiating structures, with N greater than or equal to 1, comprising at least a step where each of the radiating structures arranged parallel to each other is powered and matched in impedance for a given operating frequency value wherein it comprises at least the following steps:
- associate to one radiating structure a master function and to the other radiating structures a slave function, transmit the tuning parameters of the master radiating structure to the slave radiating structures, vary at least one of the tuning parameters so that they converge and to obtain tuning.
