Abstract
Abstract A vehicle windscreen is provided with electrical antenna conductors in the form of a row of open loops connected to at least one straight horizontal arm. The loops lie in an area corresponding to the rear view mirror position. In situ in a vehicle the loops do not project below the lower edge of the rear view mirror and the loop do not project beyond the lateral edge of the mirror. Between three and 12 loops may be provided and they may be connected to a second horizontal conductor arm. A vertical conducting arm may also be connected to the row of loops. The conductors may lie on the inner surface of the windscreen.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
138 words
A vehicle windscreen provided with electrical antenna conductors, said conductors including a plurality of open loops located in the area corresponding to the rear view mirror position, said loops being joined in succession to form a row of loops extending along an upper part of the windscreen and spaced from the upper edge of the windscreen and at least one straight horizontal arm being connected to one end of the row of loops also extending along the upper part of the windscreen, the loops forming the antenna being located in the area behind the rear view mirror position so that the loops do not project substantially beyond the lateral edges of said area and the height of the loops in the row being such that they do not project substantially below the lower edge of the said area.
Claim 2
Dependent Claim
