 技術摘要 / Our Technology： |
本發明為一種渦狀天線結構，其具有一基板、一饋訊網路以及一渦狀天線層。該基板之第一表面與第二表面上分別彼覆有金屬導電層。該饋訊網路係該基板第一表面金屬導電層所形成之一微帶線及終端，該饋訊網路具有兩個電氣端點分別形成一第一饋訊端；且具有一電氣端點連接一傳輸埠，用以提供該饋訊網路之訊號輸出入。該渦狀天線層係該基板第二表面金屬導電層所形成之一渦狀槽線；且為配合對應前述饋訊網路之各個第一饋訊端，該渦狀部具有兩個電氣端點分別形成一第二饋訊端。其中，該饋訊網路之第一饋訊端與渦狀天線層之第二饋訊端相互對應，並形成一傳遞電場以及磁場訊號之轉換器，用以傳輸該饋訊網路與渦狀天線層之間的電氣訊號。
The invention hereof is one kind of antenna, consisting of one substrate, one feeding network, and one layer of slot spirals. The two surfaces of substrate are conducting layers. The feeding network is made of microstrip lines and fan-stubs on the first surface. There are two feeding points of class 1 near the two fan-stubs, respectively. Another feeding point is used as the signal input/output. Two slot spirals are formed on the second surface of the substrate. Two fan-slots near the ends of slot spirals are designed as the feeding points of class 2, with one fan-slot matching one fan-stub on the opposite side. The fan-stubs and fan-slots form the transitions to relay the signals between the slot spirals and the feeding network.
