Description
任意で、誘電体部材は、渦巻要素を備えてもよい。渦巻要素は、フィードケーブルの近位部分および/または遠位部分の内部導体の長手方向軸を中心とするらせんを形成してもよい。渦巻(またはらせん)形状を使用すると可撓性を提供することができる一方で、電気損失を低減し、内部導体と接合部材の内壁との間の一定の間隔を維持することも可能になる。 Optionally, the dielectric member may comprise a spiral element. The spiral element may form a helix about the longitudinal axis of the inner conductor of the proximal and/or distal portion of the feed cable. The use of a spiral (or spiral) shape can provide flexibility while also reducing electrical losses and maintaining a constant spacing between the inner conductor and the inner wall of the joining member.
一実施形態では、誘電体部材16は、渦巻要素16aを備えてもよい。渦巻要素は、フィードケーブルの近位部分および/または遠位部分の内部導体の長手方向軸を中心とするらせん形状を形成してもよい。渦巻形状は、可撓性の補助に寄与し得るが、インピーダンスを一定に保ち、かつ、電気損失を低減するのにも寄与する。接合部材内の空洞内のフィードケーブルの内部導体を取り囲んでいる渦巻要素の一例を図2bに示し、この図は、渦巻要素16aの巻きを断面で示している。 In one embodiment, dielectric member 16 may comprise a spiral element 16a. The spiral element may form a helical shape about the longitudinal axis of the inner conductor of the proximal and/or distal portion of the feed cable. The spiral shape may help with flexibility, but it also helps keep impedance constant and reduces electrical losses. An example of a spiral element surrounding the inner conductor of the feed cable within a cavity in the joining member is shown in Figure 2b, which shows in cross-section the turns of the spiral element 16a.
