Claims9
Antenna (1), especially motor vehicle antenna for mobile telephony, with radiating means for receiving and sending high frequency signals, characterized in that as the radiating means a conductive area (4 to 6) which is open on both sides and which is slit lengthwise is excited to radiate in several frequency ranges.
Antenna (1) as claimed in one of the preceding claims, wherein the areas (4 to 6) are shielded in the direction in which emission is not to take place, by a metal housing body, especially a bent metal sheet (2).
Antenna (1) as claimed in one of the preceding claims, wherein the areas (4 to 6) are arranged as a copper surface on the board (3).
Dependencies are inferred from the claim text.
