技術說明

本發明提供一種無線射頻螺件天線，其包含一金屬輻射體及一迴圈電感性匹配電路，金屬輻射體包含一桿身、一頭部及一開口槽；桿身具有一徑向，頭部連接桿身，開口槽位於頭部，且開口槽的一長度方向平行徑向；迴圈電感性匹配電路設置於開口槽的一側壁。藉此，無線射頻螺件天線具有達到超高頻遠距離讀取的特性，且無線射頻螺件天線可直接鎖於物件上，具有安裝容易及方便應用之優點。 The present disclosure provides a radio frequency screw antenna which includes a metal radiant body and a loop circuit. The metal radiant body includes a shaft, a head, and a groove. The shaft has a radial direction. The head is connected to the shaft. The groove is positioned at the head, and a length direction of the groove is parallel to the radial direction. The loop inductive matching circuit is disposed at a side wall of the groove. Therefore, the radio frequency screw antenna can be operated in ultrahigh frequency and long range. In addition, the radio frequency screw antenna can be screwed into an article, and has advantages of easy installation and applicable convenience.
