技術說明

一種具有表面黏著槽孔天線之行動通訊裝置，主要包含一接地面，該接地面為該行動通訊裝置之系統接地面，在該接地面之一長邊具有一缺口，且該缺口不在該接地面之一角落處；一槽孔天線，該槽孔天線置放於該接地面之該缺口上，該槽孔天線具有一介質基底，在該介質基底之一表面上具有一金屬部，該金屬部電氣連接至該接地面，該金屬部內具有一開口槽孔，該開口槽孔之長度少於該槽孔天線最低操作頻率之1/5波長，且具有至少一彎折，於該介質基底之另一表面上，具有一饋入微帶線，該饋入微帶線跨過該開口槽孔，用以激發該槽孔天線，該饋入微帶線之另一端為該槽孔天線饋入端。 The present invention is related to a mobile communication device with surface-mount slot antenna. It comprises a ground plane and a slot antenna. There is a notch at a longer edge of the ground plane, and the notch is not at the corners of the ground plane. The slot antenna is surface-mounted at the notch of the ground plane, and the slot antenna has a dielectric substrate. On a surface of the dielectric substrate, there is a metal portion, and a monopole slot is embedded therein. The metal portion is electrically connected to the ground plane. The length of the monopole slot is less than one-fifth wavelength of the lowest operating frequency of the slot antenna. The microstrip feedline is disposed on the opposite surface of the dielectric substrate to the surface on which the metal portion is disposed. One end of the microstrip feedline passes over the monopole slot to excite the monopole slot, and the other end of the microstrip feedline is a feeding point of the slot antenna.
