摘要：

<p>A directive antenna (Ai) of reduced size for emission in the FM band comprises a supplied source (1) of the half-wave dipole type and a non supplied source (2). The non supplied source comprises at least one elongate conductor element (21, 22) extending along a lontitudinal axis (H1-H1, H2-H2) secant with the longitudinal axis (D-D) of the half-wave dipole (1). The lengthes of the dipole and of the elongate element as well as their relative positions are adapted to the desired radiation diagram of the antenna. For example, two or four elongate elements are connected to the ends (34) of an insulation leg (3) perpendicular to the center of the dipole, and to the ends (116, 126) of the dipole by means of insulation cables (41, 42).</p>
