第4圖係顯示根據本發明另一實施例所述之行動裝置200之天線結構之輻射效率(Radiation Efficiency)圖,其中橫軸代表操作頻率(MHz),而縱軸代表天線效率(dB)。根據第4圖之量測結果,行動裝置200之天線結構於第一頻帶FB1內之輻射效率可達約-3dB,而於第二頻帶FB2和第三頻帶FB3內之輻射效率可達約-5.5dB,此已可滿足一般行動通訊裝置之實際應用需求。Figure 4 shows a radiation efficiency graph of the antenna structure of the
在天線原理方面,第一輻射部130係激發產生第一頻帶FB1,第二輻射部140係激發產生第二頻帶FB2,而第三輻射部160係激發產生第三頻帶FB3,其中金屬機構件110之第一輻射部130係由位於縫隙120內之第二輻射部140所耦合激發。根據實際量測結果,短路部270之加入可微調天線結構之阻抗匹配(Impedance Matching),從而可最小化天線結構之整體尺寸。In terms of antenna principle, the
在一些實施例中,行動裝置200之元件尺寸可如下列所述。槽孔120或第一輻射部130之長度L1(亦即,由開口端121至閉口端122之長度L1,或是由第一端131至第二端132之長度L1)可以大致等於第一頻帶FB1之0.25倍波長(λ/4)。第二輻射部140之長度L2(亦即,由第一端141至第二端142之長度L2)可以大致等於第二頻帶FB2之0.25倍波長(λ/4)。連接部150於金屬機構件110上之高度H1可約介於1mm至3mm之間。第三輻射部160之長度L3(亦即,由第一端161至第二端162之長度L3)可以大致等於第三頻帶FB3之0.25倍波長(λ/4)。縫隙120之寬度W1可以大致等於第一輻射部130之寬度W2。第二輻射部140之寬度W3可以大致等於第三輻射部160之寬度W4。縫隙120之寬度W1可大致等於第二輻射部140之寬度W3之2倍,或是第三輻射部160之寬度W4之2倍。短路部270之寬度W5可約介於2mm至2.5mm之間。饋入點FP和第二短路點GP2之間距D1可小於5mm。行動裝置200之天線結構於Y軸方向上之總寬度(亦即,寬度W1和寬度W2之總和)可小於或等於4mm,以適用於窄邊框(Narrow Border)設計。以上尺寸範圍係根據多次實驗結果而求出,其有助於最佳化行動裝置200之操作頻寬(Operation Bandwidth)和阻抗匹配。第2A、2B、2C圖之行動裝置200之其餘特徵皆與第1A、1B、1C圖之行動裝置100類似,故此二實施例均可達成相似之操作效果。In some embodiments, the component sizes of the
本發明提出一種新穎之行動裝置,其包括一立體天線結構。當此天線結構應用於具有一金屬機構件之行動裝置時,由於金屬機構件可視為天線結構之一延伸部份,故能有效避免金屬機構件對行動裝置之通訊品質產生負面影響。另外,本發明之天線結構可不必依附於任何介質基板上,從而能提高天線設計之自由度。總而言之,本發明能兼得小尺寸、寬頻帶,以及美化裝置外型之優勢,故其很適合應用各種窄邊框之行動通訊裝置當中。The present invention provides a novel mobile device, which includes a three-dimensional antenna structure.
