ANTENNA MODULE

摘要

PURPOSE:To adjust the frequency and to attain a broad band by providing an adjustment member inserted between an antenna element sheet conductor and an end folded as a V-shape. CONSTITUTION:A ground conductor 2 and an antenna element conductor 3 are formed by a flexible printed circuit board formed by adhering a copper foil on a plastic film. That is, the flexible printed circuit board is adhered to a bottom face of a dielectric board 1 to form the antenna element conductor 3 and the tip of the antenna element conductor 3 has a nearly V-shaped folded part 30. Then an adjustment member 4 as a post-mount component is inserted into the nearly V-shaped part 30. Then the adjustment member 4 is inserted to the folded part 30 of the antenna element conductor in nearly V-shape to short-circuit electrically both ends of the nearly V-shaped folded end 30 by a conductor 41 of the adjustment member 4 to adjust effectively the length of the antenna element conductor 3.
