技術說明

本發明係關於一種多頻行動通訊裝置天線，包含：一電路板、一接地面及一天線元件。該天線元件並包含：一介質基板、一輻射金屬部及一饋入金屬部。該介質基板位於該電路板之無接地面區間附近。該輻射金屬部及該饋入金屬部均位於該介質基板上。該饋入金屬部並包含：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，其一端連接至一訊號源，且該第二金屬元件並與該第一金屬元件之間具有ㄧ特定間距；該短路金屬元件其一端電氣連接至該第一金屬元件，另一端則短路至該接地面。 The present invention is related to a multiband mobile communication device antenna. The antenna comprises a circuit broad, a ground plane, and an antenna element. The antenna element consists of a dielectric substrate, a radiating metal portion, and a feeding portion. The dielectric substrate is located at near the no-ground region of the circuit board. 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, and there is a specified distance between the second metal element and the first metal element. 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.
