Abstract (en)

[origin: EP2784874A2] The antenna (0) has an upper band monopole (1), a lower band monopole (2) and an electrically conductive structure i.e. electrically conducting foil, oriented above a conducting base surface (6). A triangular structure (4) is formed at a lower end of the antenna. A roof capacitor (10) designed as a rectangular structure (16) is arranged below an upper end of the antenna. The triangular structure and the rectangular structure are connected inductively with high impedance by a conductor strip (15) for separating radio signals in the upper band.
