• An antenna for automobiles is also known for example from DE 298 21 723 ul.
• the antenna comprises an antenna base, which consists of a housing or hood-shaped protective cover and a base plate that can be mounted on the car roof.
• Various electrical devices are housed between the hood and the base plate.
• a line 12 leads to the actual radiator devices projecting outwards from the foot part.

• antenna base in order to finally be able to receive different frequency ranges via one or more high-frequency lines.
• Such antennas are said to be suitable, for example, for the mobile radio range in the different networks (for example D network or E network, but also for the new UMTS frequency range from approximately 1900 MHz to 2170 MHz).
• a two-range antenna is from US 6 191 747 in Bl known. It is a multi-range antenna using phase shift coils to build a monopole gain antenna.
• the object of the present invention is therefore to create an improved multi-range antenna arrangement based on the generic state of the art.
• a very well-proven motor vehicle antenna can now also be used, for example, for the UMTS standard, that is to say generally speaking, for a significantly higher frequency band, and this without reducing the overall height or size.
• the extension can be implemented in such a way that the supply lines are extended beyond a connection or contact point, via which the radiator is electrically contacted with the supply line, and preferably ends freely. If the electrical feed line is formed by an electrically conductive bracket, the bracket can be extended beyond the contact point with the first radiator, the contact point also serving as a connection or even fastening point for the radiator.
• the extension does not necessarily have to be provided continuously and continuously on the electrical wire or bracket, but can also be formed in the form of a returned line section. It is also possible to use the connection point between the electrical feed line or bracket and the electrical radiator provided for the higher frequency range, which extends shortly before the motor vehicle roof.
• Extensions are also suitable, e.g. are designed in the form of a disk or a plate, and are preferably provided at the connection point between the electrical supply line or bracket and the radiator provided for the higher frequency range.

• the transmitting and / or receiving device comprises an antenna base 3 which is designed in the manner of a housing 5.
• the housing 5 preferably comprises a hood-shaped protective cover 5a and a base plate 5b which can be attached to the body panel 1 by suitable measures, for example using adhesive layers, insulating materials, etc.
• At least one opening 9 is generally provided in the body panel 1, via which electrical connecting lines, coaxial cables, etc. to the antenna can be laid from the interior of the motor vehicle.
• the base plate of the antenna housing is correspondingly placed on the motor vehicle roof, usually (which is not shown in the drawings but is sufficiently known), a threaded dome designed as a hollow threaded rod is used, which is anchored in the base plate and into the motor vehicle roof via the opening 9 Vehicle interior protrudes into it. Through the inside of the thread doms are then routed inwards. A central nut can then be screwed onto the threaded dome from the inside of the car in order to firmly anchor the antenna to the motor vehicle roof.

• the first radiator 17 can consist, for example, of a metallically conductive bolt or have a bolt structure.
• the second radiator 21 should be as elastic as possible and can consist, for example, of a glass fiber core which is wrapped with a corresponding coil-shaped, electrically conductive arrangement. All possible antenna designs are conceivable that are suitable and suitable for the respective application.
• the entire antenna arrangement including the antenna bracket acts as an antenna.
• the antenna bracket and the lower part of the actual radiator arrangement ie usually the radiator pin provided for this purpose, together with part of the coil mentioned, act as radiator.
• the frequency is raised further, namely in the GSM 1800 and GSM 1900 bands (corresponds to 1710 MHz to 1990 MHz), only the antenna bracket and the lower antenna bolt act as radiators.
• the antenna bracket and its extension act as a radiator.
• the coil 19 blocks for high frequency ranges, for example in the E network (approximately 1800 MHz) or, above all, for the UMTS standard (approximately 1900 to 2170 MHz), so that only the first radiator 17 together with the electrical one acts as the radiator element for this purpose Connection line 13 act.
• connection line 13 mentioned can preferably also consist of an at least slightly elastic or partially elastic bracket 13 ', which is preferably biased in the direction of the radiator.
• the radiator arrangement 15 can usually be connected to the antenna housing 5 by means of a screw connection, so that the antenna, in particular when motor vehicles are being driven into a washing system, can be unscrewed beforehand without problems and then screwed on again.
• the actual radiator arrangement 15, which can be screwed onto the housing, is ultimately held and supported via the housing itself.
• the first radiator preferably in the form of a bolt 17, but also the electrical connection line 13 would have to be matched for the high frequency band range. be wrested.
