Abstract

The device has a continuous radiating structure (10) formed by waveguides of a rectangular section presenting three sections (a, b, c) pierced with a series of slots (12, 14, 16) respectively. A microwave signal is injected into the slots. An energy transition unit transmits energy between the structure and a Yagi type directive antenna, where the sections are adjacent and consecutive to each other. Large dimension of the slots (14) progressively extends on length of the section (b).
