Embodiment Construction

[0029] figure 1 An antenna designed according to the invention is shown for use in a receiver or transmitter in a motor vehicle, here in a tire condition monitoring system. The antenna has a conductive loop 1 which, as shown in the exemplary embodiment, is mounted on a base body 2, for example made of plastic. The base body 2 has a substantially cylindrical shape, wherein two flat sides 2.1 and 2.2 facing away from each other are arranged across its outer circumference. In the present case, the flat side 2.1 is designated as the front side and the flat side 2.2 as the rear side. The base body 2 also has an upper end face 2.3 and a lower end face 2.4. The upper end face 2.3 is closed, while the lower end face 2.4 is open, see figure 2 , figure 2 Front view showing lower end face 2.4.

[0030] The electrically conductive loop 1 now extends diagonally across the lower end face 2.4, for which purpose a web 5 is passed through the lower end face 2.4, which runs in a diagonal...

Abstract

The invention relates to an antenna for a receiver or transmitter in a motor vehicle, comprising an electrically conductive loop, which surrounds an area for the passage of electromagnetic waves, which interact with an electric current flow through the loop. The loop has a connection side, via which an electric current can be introduced into the loop or drawn from the loop inductively or by means at least one electrical connection. The antenna according to the invention is characterized in that the area surrounded by the loop is twisted over a twist axis that is perpendicular to or at an angle to the connection side.

Description

technical field [0001] The invention relates to an antenna for use in a receiver or transmitter in a motor vehicle, in particular for a tire condition monitoring system, for example for recording air pressure and / or temperature and / or Other state variables, such as direction of rotation or rotational speed (number of revolutions per unit time). Background technique [0002] Tire condition monitoring systems, particularly tire pressure monitoring systems, are known in various embodiments. By positioning sensors in or on the tire so that conditions in the tire, such as pressure or temperature, can be monitored, the sensor records the desired state variable, such as the air pressure of the tire, and sends it via an attached or integrated transmitter to A receiving device on the outside of a tire in a vehicle. The receiving device can relay the transmitted data or evaluate itself, so that undesired states of the tires, such as tire pressure that is too low, can be registered a...
