Abstract
Abstract A sheet composed of two superimposed laminae of electrically non-conductive synthetic plastic foil material has a pair of triangular antenna elements of metallic foil sandwiched between them. The apices of the metallic foil elements are adjacent but spaced from one another and their bases are remote from and at least substantially parallel to each other. Antenna conductors are connected with the antenna elements in the region of the apices thereof and have free ends for connection to a user device.

Claim 1
Independent Claim
151 words
A high frequency aNtenna, comprising a sheet composed of two superimposed laminae of electrically non-conductive synthetic plastic foil material; a pair of triangular antenna elements of metallic foil sandwiched between said laminae and having respective apices adjacent but spaced from one another and respective bases remote from and at least substantially parallel to each other; signal conductors connected with the respective antenna elements in the region of the apices thereof, and having free ends for connection to a user device; and connecting terminals connecting said conductors with said antenna elements and each having a portion piercing the respective laminae so as to make electrical contact with the respective antenna element from the exterior of said sheet, said laminae being provided outside the outline of said elements with a plurality of holes; and wherein said conductors extend through said holes alternately at one side and at the opposite side of said sheet.
