技術說明

本發明係關於一種雙寬頻行動通訊裝置，其具有接地面及天線。天線及接地面位於電路板上，且天線位於電路板之一角落處，為接地面所圍繞，接地面與天線之外圍之最短距離小於3 mm，天線包括第一金屬部及第二金屬部。其中第一金屬部之一端為天線之饋入端，其另一端為開路。第二金屬部之一端短路至接地面，其另一端為開路，第二金屬部之長度係為第一金屬部之長度之1.25倍至1.75倍之間，且第二金屬部大致為天線之外圍，並包圍第一金屬部，使得第二金屬部與第一金屬部之間具有耦合間距，第二金屬部藉由耦合間距電容性耦合由第一金屬部激發。 The present invention is related to a dual-wideband mobile communication device which comprises a ground plane and an antenna. The antenna is located at a corner of the circuit board and surrounded by the ground plane. The distance between the ground plane and the boundary of the antenna is less than 3 mm. The antenna comprises a first metal portion and a second metal portion. One end of the first metal portion is the feeding port and the other end is open. One end of the second metal portion is short-circuited to the ground plane and the other end is open. The length of the second metal portion is 1.25 to 1.75 times that of the first metal portion. The second metal portion is substantially the boundary of the antenna. The first metal portion is surrounded by the second metal portion, and there are coupling gaps between the first metal portion and the second metal portion. The second metal portion is excited by the first metal portion through the coupling gaps.
