技術說明

本發明係一種電容耦合饋入手機天線，包含：一接地部、一輻射部、一短路金屬線及一饋入連接線。該輻射部大致位於該接地部之一短邊附近，並包含：一介質基板、一輻射金屬片及一耦合部；該介質基板具有一第一表面及一第二表面；該輻射金屬片位於該介質基板之第一表面上，並具有一短路點；該耦合部位於該介質基板之第二表面上，並具有一饋入點；該短路金屬線之一端電氣連接至該接地部，另一端則電氣連接至該輻射金屬片上之短路點；該饋入連接線之一端電氣連接至該耦合部之饋入點，另一端則電氣連接至位於該接地部上之一信號源。 The invention is related to a mobile phone antenna having a capacitive feed. The antenna comprises a ground portion, a radiating portion, a shorting metal strip and a feeding connection line. The radiating portion is located at about a short edge of the ground portion, and consists of a dielectric substrate, a radiating metal plate and a coupling portion. The dielectric substrate has one first surface and one second surface. The radiating plate having a feeding point is on the first surface of the dielectric substrate. One end of the shorting metal strip is electrically connected to the ground portion, and another end is electrically connected to the shorting point of the radiating metal plate. Meanwhile, one end of the feeding connection line is electrically connected to the feeding point of the coupling portion, and another end is electrically connected to a signal source on the ground portion.
