Abstract
A reflector network antenna (A) comprising i) a source (S) delivering wave signals; ii) at least two reflector networks (RR1-RR9) which are different and independent and which both comprise at least two phase shifter cells which selectively phase shift the waves delivered by the source (S) and bring about a selected frequency phase dispersion thereof, said selective phase shifting and selective dispersion varying from one reflector network to another; and iii) a charging device (DC) which is coupled to the reflector networks (RR1-RR9) and which is used to place one of them in a selected position in relation to the source (S) such that the waves that it delivers are phase shifted and phase dispersed at a frequency imposed by said phase shifter cells in order to be reflected in a selected direction.
