Abstract
A vehicle antenna for mobile telephones includes a portion, which shall interact with a second portion, as a capacity coupling for wireless signals transmitted by an antenna. A second portion is attachable on the outside of a window of the vehicle and includes the antenna means. The first portion is connectable to the mobile telephone within the vehicle via a lead. In order to arrange the first portion of the capacity coupling permanent on the window so that it is ready for use when the window is distributed for assembly in the vehicle, said first portion of the capacity coupling is an electric conducting pattern (2, 3), which forms a ground plane (2) and one part (3) of the capacitance. The pattern is applied on the surface of the window, and the lead (7) is conductively connectable with the conducting pattern (2, 3) by means of free terminals (4, 5) belonging to the pattern.
Description
GLASS ANTENNA
This invention relates to a vehicle antenna for mobile telephones including a portion, which shall interact with a second portion, as a capacity coupling for wireless signals, which second portion is attachable on the outside of a window of the vehicle and which includes an antenna means, said first portion being connectable to the mobile telephone within the vehicle via a lead.
The object of the invention is to arrange the first portion of the capacity coupling permanent on the window so that it is ready for use when the window is distributed for assembly in the vehicle. The arrangement should be so prepared that the lead to the mobile telephone easily can be connected to said portion.
In order to reach above stated object of the invention, the invention has the characterizing features stated in the following claims.
An embodiment of the invention will now be described with reference to enclosed drawings.
Fig. 1 a plan view showing the first portion of the capacity coupling according to the invention.
Fig. 2 is a perspective view of the second or outside portion of the capacity coupling including an antenna.
The wireless signals transmitted by an antenna, which can be applied on the outside of a window of a vechicle, are conducted to the inside of the window by means of a capacity coupling. The inside portion of said capacity coupling is shown in fig. 1 and consists of a ground plane 2 and a capacity plate 3. These two means are in the form of an electric conducting pattern, as can be seen from fig. 1, and are applied on the inner surface of the window. There is one terminal 4 going from the ground
plane and a second terminal 5 going from the capacity plate 3. These two conductors are free from the window and are thus connectable with the lead going to a mobile telephone.
The electric conducting pattern 2, 3 can be applied by several methods. One is by screen printing on the inner side of the window. A second method is to paint an electric conducting paint on the inside of the window' with the pattern shown in fig. 1. Further it is possible to apply the pattern by gluing or pressing it in the glass surface during a later stage of the glass manufacturing. It should also be noted that when the window is a multi-layer glass the pattern can be applied to an inner layer when forming the multi-layer glass.
Fig. 2 shows the second or outside portion of the capacity coupling. This portion does not form a part of the invention. Thus fig. 2 shows a conventional antenna 1, which is connected to a plate 6. This plate forms the other part of the capacitance and thus interacts with the electric conducting pattern shown in fig. 1. The plate 6 is applied to the outside of the window by gluing when the window has been assembled in the vehicle. The signals from the antenna are thus conducted through the window by the capacitive coupling formed by the plate 6 and the pattern 2, 3 in the glass. The signals are then conducted to the mobile telephone by the lead 7, which is connected to the terminals 4, 5 by a suitable connector means 8. This connector means can include a matching means for the matching between the antenna and the mobile telephone. It is thus very easy to complete the antenna arrangement as soon as the window is assembled in the vehicle. First the antenna 1 and 6 is glued to the outside of the window opposite to the place where the electric conducting pattern is applied. Then the lead and the connector means are connected with the terminals 4 and 5 and the mobile telephone is ready to be used.
