^w Motor vehicle antenna with antenna conductors on or in a transparent pane «"

Duroh the! Firing has solved the problem «powerful antennas for motor vehicles in as simple a catfish as possible spend «which are located inside the vehicle and already used for other purposes *

The hiring consists in the antenna conductor on or in one transparent disc are arranged, which are attached to a fesstevselielfe of the motor vehicle is to be attached *

The newly improper antenna is primarily sifen Rundfunkevpfsmg In motor vehicles, «Ba the dog radio waves penetrate the metal body of the vehicle only a little, is the effect« «· an antenna installed inside the car on the window is better than in the interior «

In an advantageous embodiment of the new antenna are the antenna conductors on or in a transparent pane «dt Heating conductors attached and the heating conductors are not conductively connected to the antenna conductors. Well-known hot plates are e.g. Rear window of the vehicle attached to fogging and in winter also to prevent the hay from freezing over. You could think of it now think of using the heating conductor soloher Soheiben as an antenna conductor -

Then you would have to use the Heizgleiehstrom and the Hoohfrequenzetrom by separating a switch from one another «This switch can consist of a capacitor in the high-frequency conductor and a choke in the heating conductor The choke in the heating conductor would have to be made of thick copper wire wound so that the voltage drop it causes is not too great. Such chokes would, however, be too large and too expensive. Therefore it is better to use separate conductors for the heating and for the antenna, which are not connected to each other «

In another advantageous embodiment of the invention »

According to the antenna, the antenna conductors are on or in a through · » visible disc attached, which is at a small distance from the

The window pane of the motor vehicle is to be attached to the loading

to prevent hitting the window pane "

For this purpose, panes without antenna conductors are preferred -

wisely attached to the inside of the rear window «

An advantageous embodiment of the antenna according to the invention is

it says that several antenna conductors parallel to each other are provided to make the antenna as sensitive as possible «

These antenna conductors can conductively with one another at both ends

connected «A connection line can be connected to one end of the

Antenna conductors can be connected * But it is also possible that the Antenna conductors in the middle to be conductively connected to each other and

to connect the connection line in the middle «

It is advantageous to use antenna conductors that are so thin that they

do not significantly impair the view through the transparent pane "

They Fig «show basic sketches of two embodiments of the

antenna according to the innovation "FIGS. 1 and 2 each show a view of two embodiment examples «Figures 3 and 4 are a longitudinal section and a cross section through the second embodiment «

In the embodiment according to FIG. 1, 1 is on a window pane

preferably the Heok disc of a motor vehicle a second transparent Disc 2 placed and fastened in the usual way, e.g. glued on "

In the lower part of the disk 2 there is a meandering back and forth

attached heating conductor 3, the ends 4 and 5 »n the (The vehicle's direct current battery must be connected «

In the upper part of the base 2 there are seven antenna conductors 6,

extending at a small distance from each other in a horizontal direction parallel to each antenna conductor 6 · They are by cross -> Compounds 7 and θ connected to each other at both ends ·

At the cross connection θ is a feed line 9 ^{to the} inner conductor of a

as a connection line serving coaxial cable Io attached «

In the embodiment according to FIGS. 2-4, a window -

pane H ₉ preferably on the Heok pane of a motor vehicle, a second thermoset pane is attached, the middle part of which is lowered in the shape of a plate relative to the outer edge 13. The edge is attached to the window pane 11 in any way, e.g.

The middle pane part 12 is approximately to the window pane 11

parallel and has a small distance from it * Through the through «· visible soleplate 12/15, the fogging of the rear soleplate becomes one

Motor vehicle prevents the view through the rearview mirror after

to get in the back "

Seven antenna conductors 14 are provided in the middle pane part 12.

see those parallel to each other at a small distance from each other in run horizontally · The antenna conductors 14 are connected to each other at both ends by cross connections 15 «

A third cross connection 16 in the middle of the antenna conductors 14

continues in a connecting conductor 17, which is connected to the inner conductor of a coaxial cable 18 · the coaxial cable 18 serves as a connection cable for a radio receiver *

Terbund washers are used as transparent panes with heat conductors

used where a thin wire in the plastic layer is used as the heating conductor is embedded between two panes of glass. The antenna conductors of the first

Embodiment are embedded «on glass panels or

transparent plastic panes, however, heating conductors are also applied as narrow strips in a similar way to the known ones printed circuit boards of electrical devices «In this way, the antenna conductors of the two exemplary embodiments can be produced will*

Well-known panes that prevent the vehicle windows from misting up without affecting prevent heating, made of transparent plastic «
