  • Patent number: 8643550
    Abstract: A flexible antenna comprises a filmed layer, a flexible radiation conductor and a support member. The flexible radiation conductor has a crooked form and a feeder terminal. The filmed layer covers the upper surface of the flexible radiation conductor. The support member has a through-hole. The lower surface of the flexible radiation conductor is stuck to the upper surface of the support member. The feeder terminal is inserted through the through-hole to protrude from the lower surface of the support member. The flexible radiation conductor and the crooked feeder terminal thereof replace the conventional radiation conductor circuit layer and metallic contact terminal to overcome the problem that the conventional contact terminal damages the radiation conductor layer and protrudes the filmed layer. Further, the present invention integrates FPC and LDS technologies to enable the flexible radiation conductor to be arbitrarily stuck to complicated planes or complicated curved surfaces.
