技術說明

本發明係有關於一種可抑制頻帶之十字形單極天線，其係設一中央具有穿孔的接地金屬面，於穿孔處對應穿設接頭以組裝天線主體，而該天線主體為兩矩形金屬片交叉重疊成立體十字形狀，並針對該十字形單極天線嵌入小h形槽孔之設計，使十字形單極天線俱有帶拒功能，將不需要的頻帶5.25GHz~5.85GHz加以濾除，另外還有一高頻帶拒特性可操作。故擁有抑制雙頻之效果，並且可改善主體結構在高頻時會產生漣波效應，進而達成全方向性的效果。 The band-rejected design of the cross monopole antenna is proposed. That is fabricated from a copper twin sheets and vertically mounted on a finite square ground plane. And, a via-hole in the ground plane at the center of the monopole’s lower edge for easy connection to a 50Ω SMA connector for signal transmission. Finally, by embedded four small h-shaped slots on each lobe of cross monopole antenna, the dual-band rejected operation is obtained. Furthermore, which can be easily varied to control rejected band by varying the size of small h-shaped slots and the antenna also maintain omnidirectional radiation. In this proposed, we varied the first rejected band to conform WLAN band (5.25GHz~5.85GHz) to decline the interference between WLAN and UWB system, another rejected band also can be used to decline the interference from the other wireless system.
