Description

天線模組
本發明涉及一種天線模組,尤其涉及一種輻射性能較佳之天線模組。
用於行動電話、個人數位助理(personal digital assistant,PDA)等無線通訊裝置之單極化天線於使用時,其下方必須有面積足夠大之淨空區,以確保該天線之輻射特性良好。然,習知之無線通訊裝置為節省裝設空間,經常將高清晰度多媒體介面(High Definition Multimedia Interface,HDMI)連接器、通用串列匯流排(Universal Serial BUS,USB)連接器、揚聲器等多種金屬器件設置於單極化天線附近。如此,很容易破壞單極化天線之淨空區,影響該天線之輻射特性。
針對上述問題,有必要提供一種輻射性能較佳之天線模組。
一種天線模組,包括載體及天線,該載體中部位置設置有開口,所述天線包括第一輻射單元、第二輻射單元及饋入單元,該第一輻射單元及第二輻射單元分別用以激發出相應之低頻模態及高頻模態,所述饋入單元連接至所述第一輻射單元及第二輻射單元,且穿過所述開口,並卡持於所述開口之側壁。
上述天線模組藉由將所述饋入單元及接地單元從習知之載體之側 面移動至所述載體之中部位置,即移至所述HDMI連接器、USB連接器等多種金屬器件之背面,以背離該等金屬器件,獲得較佳之隔離效果,進而有效改善該天線模組之輻射效率。

圖3為圖1所示天線模組之返回損失示意圖。
請一併參閱圖1及圖2,本發明提供一種天線模組100,裝設於行動電話、個人數位助理(personal digital assistant,PDA)等無線通訊裝置內,並於複數個頻段進行發射、接收無線電波以收發無線電訊號。
該天線模組100包括載體10及天線20。該載體10用於承載該天線20。該載體10大致呈矩形罩體狀,包括水平之承載面11、與該承載面11垂直相連之側面12、13、14。該承載面11與該側面12、13、14共同圍成一大致呈矩形之容置部15,用於容置高清晰度多媒體介面(High Definition Multimedia Interface,HDMI)連接器、通用串列匯流排(Universal Serial BUS,USB)連接器、揚聲器等金屬器件。該承載面11之中部位置開設有大致呈矩形之開口111,該開口111與該容置部15相通。
該天線20為一單極化天線,由金屬等導電材料製成之片體製成。該天線20包括第一輻射單元21、第二輻射單元22、共振單元23、饋入單元24及接地單元25。
該第一輻射單元21沿該承載面11靠近側面12之邊緣位置設置,且部分佈設於該側面12、13上,用於激發出一相應之低頻模態。為獲得更佳之低頻通訊品質,如圖所示,第一輻射單元21之末端寬度還可適當增大。
該第二輻射單元22與該第一輻射單元21相連,且沿遠離該第一輻射單元21之方向延伸,並且部分佈設於與該側面12相鄰之另一側面14上。該第二輻射單元22之長度小於該第一輻射單元21之長度,用於激發出一相應之高頻模態。
該共振單元23為一條狀片體,整體設置於該承載面11上,用於激發出一相應之高頻共振模態。該共振單元23與該第二輻射單元22設置於該第一輻射單元21之同一側,且與該第二輻射單元22之延伸方向一致並構成一定之夾角。該共振單元23之長度小於該第二輻射單元22之長度。
該饋入單元24大致呈鉤狀,與該第一輻射單元21及第二輻射單元22相連,且沿遠離該第二輻射單元22之方向延伸,並經過彎折,以穿過該開口111,進而斜向延伸至與承載面11相背之平面內,以卡持該開口111之側壁。該饋入單元24與設置於無線通訊裝置內部之電路板上之習知之訊號傳輸端(圖未示)電性連接,以為所述天線模組100起訊號饋入作用。
該接地單元25連接於該共振單元23之端部,且與該饋入單元24平行設置。該接地單元25之形狀及結構與該饋入單元24之形狀及結構相當,於此不再贅述。該接地單元25可與電路板上之習知之接地部分相連,以為所述天線模組100提供接地作用。
請參閱圖3,所示為本發明天線模組100之返回損失(return loss,RL)測量結果示意圖。由圖中可看出,該天線模組100可涵蓋至GSM850、EGSM900、DCS1800、PCS1900、WCDMAI、WCDMAII、WCDMAIV、WCDMAV及WCDMAVIII等複數個通訊系統。
請參閱表1,所示為本發明天線模組100之平均效率。由表1可知,該天線模組100於平均效率均滿足天線工作設計要求。
顯然,本發明之天線模組100藉由將所述饋入單元24及接地單元25從習知之載體10之側面移動至所述載體10之中部位置,即移至所述HDMI連接器、USB連接器等多種金屬器件之背面,以背離該等金屬器件,獲得較佳之隔離效果,進而有效改善該天線模組100之輻射效率。另外,該天線模組100藉由設置該共振單元23,以激發出相應之共振模態,有效拓寬天線模組100之高頻及低頻範圍,使得天線模組100可具備足夠寬之訊號收發頻率。
