Multiband antenna comprising a dielectric support, an aerial and an electronic circuit supported by the support

摘要

The aerial (1) has an electronic circuit (5) mounted on a rectangular shaped dielectric support (10). An aerial (20) made of a copper etched conductive wire is connected to the electronic circuit. Parts (21, 23) are symmetrically arranged on sides of a symmetrical longitudinal axis (15) of the support. The parts have a wire formed by meanders constituted by a pattern comprising transversal and longitudinal sections (21b-25b) located at interior of transversal and longitudinal sections (21a-25a). The pattern is repeated for twelve times in a centre direction (C) of the support. The support is made of glass fiber. The electronic circuit is protected by an overmolded plastic coating.
