Abstract

Radio communication device The invention concerns a radio communication device (10, 20) having a continuous radiating structure (a) pierced by a first series of slots (12), into which a microwave signal is injected, a directional antenna (c) and a means (b) for transition of energy between the continuous radiating structure (a) and the directional antenna (c) characterised in that said transition means (b) and said directional antenna (c) consist respectively of a second section and a third section of radiating structure.
