More structure broadband monopole antenna for two by a frequency gap separate frequency bands in the decimeter for vehicles

Vertical multi-texture broadband monopole antenna for vehicles for two by a frequency gap separate frequency bands, namely a sub-band for lower frequencies and a top belt for higher frequencies, both located in decimeter, for transmission and / or reception with terrestrial broadcast vertically polarized radio signals over a substantially horizontal conductive surface area than vehicle mass at a base point located in the monopole antenna connection point, comprising the following features: - the multi-texture broadband monopole antenna is formed of a first and a further electrically conductive structure which is oriented in each case above the base surface (6) substantially perpendicular to this - the first electrically conductive structure comprises at the lower end of the multi-structure broadband monopole antenna at least one standing on a top triangular structure having a substantially horizontally oriented base line whose tip forms an antenna connection point of the antenna connection point - the first electrically conductive structure comprises adjacent the upper end of the multi-texture broadband monopole antenna including a substantially rectangular structure is designed as a first first roof capacity - the triangular structure and the first rectangular structure are inductively coupled to high impedance by at least a first conductor strip for the separation of radio signals in the high band - the further electrically conductive structure comprises a further substantially configured as a rectangular structure, for capacitively coupling to the first roof capacity in a roof capacitor coupling distance - <λ / 30 at the lowest frequency of the sub-band U - substantially parallel to the first rectangular structure guided more top-loading capacity, - the further electrically conductive structure comprises at least one connected with the other rectangular structure and the conductive base surface and extending conductively connected with this at its lower end, for the separation of radio signals in the high band O inductive high impedance further conductor strips;
