Abstract
An antenna installation for radio and television reception in motor vehicles in the meter and decimeter frequency wave ranges with a first antenna and-at least one additional antenna on the vehicle. The receiving signal available at each connection point of the antennas are combined in a collecting network. The signal then flows out of the collecting network to a reception point to form an overall receiving signal. The line and collecting network is designed to select the highest possible reception quality for a motor vehicle moving through a reception field based upon a statistical average.
Claims22
An antenna installation for radio and television reception in motor vehicles in the meter and decimeter wave ranges, comprising:
- a first antenna for receiving signals;
- at least a second antenna for receiving signals;
- a collecting network for receiving signals from said first antenna and said at least a second antenna;
- at least one electrical connection line with each line connecting said first antenna and said at least a second antenna to said collecting network said at least one connection line for transmitting the signals received from said antennas;
- at least one connection point formed where said at least one connection line contacts said first antenna and said at least a second antenna;
- a reception line connected to said collecting network said reception line for transmitting signals received by said collecting network;
- and
- a collecting connection point formed by the connection of said reception line to said collecting network wherein the received signals available at each of said at least one connection point of the antennas are combined in an overall receiving signal and the collecting network is designed to select the highest possible reception qualities from said signals based upon a statistical average of the signals in the moving vehicle, and transmit this resultant signal through said collecting connection point to said reception line.
An antenna installation disposed on a motor vehicle windowpane glass said antenna installation for radio and television reception in the meter and decimeter wave ranges, comprising:
- a first antenna for receiving signals;
- at least a second antenna for receiving signals;
- a collecting network for receiving signals from said first antenna and said at least a second antenna;
- at least one electrical connection line with each line connecting said first antenna and said at least a second antenna to said collecting network said connection lines for transmitting the signals received from said antennas;
- at least one connection point formed where said at least one connection line contacts said first antenna and said at least a second antenna;
- an electrically conductive frame surrounding the windowpane;
- a ground point forming a HF-reference ground on the frame;
- an antenna connection point formed by the connection of said ground point and said at least one connection point;
- a heating field formed by a series of wire-shaped electrical conductors disposed on said windowpane glass wherein said electrical conductors extend substantially perpendicular to said first and said at least a second antenna;
- a plurality of coupling points disposed where antennas contact an edge of the heating field wherein said coupling points are formed near the point of contact of the cross conductor and the outermost heating conductor on an edge of the heating field;
- a reception line connected to said collecting network said reception line for transmitting signals received by said collecting network;
- and
- a collecting connection point formed by the connection of said reception line to said collecting network, wherein the received signals available at each of said connection points of the antennas are combined in an overall receiving signal and the collecting network is designed to select the highest possible reception qualities from said signals based upon a statistical average of the signals in the moving vehicle, and transmit this resultant signal through said collecting connection point to said reception line.
