Patent ID: 7106263

Claim:
A window-integrated antenna for LMS and FM reception in a mobile motor vehicle, comprising: a window pane in the motor vehicle; a metallic frame enclosing the window pane; and a first antenna, the window pane, line structures of the first antenna and the metallic frame being used as an antenna for reception of LMS and USW signals, a first point of the first antenna being situated in a region of one of the corners formed by the metallic frame, in proximity to which a mechanical component used as a USW/LMS antenna unit is also positioned; wherein the first antenna includes four conductor sections positioned perpendicularly to one another, the first antenna being integrated into the window pane of the motor vehicle for both LMS and FM reception, a first short one of the conductor sections of the first antenna originating from a first-connection point on an upper horizontal frame part of the metallic frame in a region of one of two upper corners formed by the metallic frame and being positioned at a distance to a first lateral frame part of the metallic frame situated closest thereto, three further ones of the conductor sections adjoining the first one of the conductor sections forming one of: i) an angle of 90° in each case, or ii) a radius which is implemented as a quarter circle having a small radius, the four conductor sections forming a loop, and wherein the mechanical component is connected to the first connection point via a signal path and accommodates passive or active assemblies which provide reception functions for an LMS or a USW receiver, and wherein a resonance response in FM range is provided by the formation of the loop in connection with a capacitive effect of the metallic frame.
