技術說明

本發明係關於一種行動通訊裝置天線，主要包含：一電路板、一接地面及一天線元件。該天線元件位於該電路板之無接地面區間上。該天線元件並包含：一介質基板、一輻射金屬部及一饋入部。該輻射金屬部及該饋入部均位於該介質基板上。該饋入部並包含：一第一金屬元件、一第二金屬元件及一短路金屬元件。該第一金屬元件其一端電氣連接至該輻射金屬部；該第二金屬元件，其一端經由ㄧ饋入金屬連接線電氣連接至一訊號源；該短路金屬元件其一端電氣連接至該第一金屬元件，另一端經由ㄧ短路金屬連接線短路至該接地面。 The present invention is related to a mobile communication device antenna. The antenna comprises a circuit broad, a ground plane, and an antenna element. The antenna element is located on the no-ground region of the circuit board. The antenna element consists of a dielectric substrate, a radiating metal portion, and a feeding portion. The radiating metal portion and the feeding portion are both on the dielectric substrate. The feeding portion comprises a first metal element, a second metal element, and a shorting metal element. One end of the first metal element is electrically connected to the radiating metal portion. One end of the second metal element is electrically connected to a source by a feeding metal connecting strip. One end of the shorting metal element is electrically connected to the first metal element, and the other end of the shorting metal element is short-circuited to the ground plane by a shorting metal connecting strip.
