Wide band antenna for mobile communications.

摘要

In order to provide an increased resonant band width for an antenna device for vehicles on a ground plate (2) having a flat surface a L-shaped radiator plate (5) is attached having one leg (5a) of L arranged parallel to said ground plate (2) with the other leg (5b) being positioned perpendicular to said ground plate (2), said radiator plate being disposed having a narrow gap (6g1) between the lower end (5c) of said vertical leg (5b) and the upper surface of said ground plate; further a sub-radiator element (7) formed by a L-shaped plate is rigidly mounted on said ground plate (2) at a position in close proximity to said radiator plate (5) the free ends (5d, 7b) of said radiator plate (5) and of said sub-radiator element (7) having a given distance (8g2).
