Patent ID: 7138954

Claim:
An antenna arrangement having a flat dipole which is arranged on a substrate, comprising: dipole halves including end areas, the end areas which point towards one another each being electrically connected to respective connecting line, plural amplifiers, the connecting lines leading to said plural amplifiers, a transformer; the plural amplifiers having outputs, the outputs of the plural amplifiers being connected to the two inputs of the transformer, the output of the transformer being at least indirectly electrically connected to a coaxial connection point, plural filters, the dipole halves being arranged on the substrate together with the plural amplifiers and the plural filters, the plural filters being arranged between the connecting lines which lead to the dipole halves, and the connection point, the filters being provided for suppression of mobile radio frequency ranges and/or as protection for broadcast radio signals, a low-pass filter connected between the outputs of the plural amplifiers and the connection point in order to suppress mobile radio frequencies (cellular telephone frequencies), and a bandstop filter connected between the outputs of the plural amplifiers and the connection point.
