  • Publication number: 20170229780
    Abstract: The disclosure is related to a planar printed antenna and a system thereof. The antenna is characterized in that a signal feeding direction is essentially the same as the extended direction of antenna radiation member. For a layout space, the antenna is suitably applied to a product with limited space. The direction of feeding signals fed to the antenna is essentially the same as the extended direction of the radiation member of the antenna. Therefore, the signal loss can be reduced. Structurally, the planar printed antenna has a radiation member and a connection member. The connection member includes at least one transition portion. A feeding point is formed at a joining member between the radiation member and the connection member. In addition to the structural feature of the antenna, the feeding point and the grounding point are at different planar sides.
