阅读说明：本技术 螺旋段天线 (Helical segment antenna ) 是由 塞德里克·马泰尔 杰罗米·马西奥特 奥利维厄·帕斯卡尔 娜撒莉·拉沃 于 2019-09-06 设计创作，主要内容包括：一种发射来自沿着引导路径传播的至少一个电磁行波的辐射的天线(100)设计成减少很可能在所述引导路径末端处发生的所述行波的反射。为此目的,所述引导路径具有呈螺旋段(11、12)形式的至少一个部分,所述至少一个部分连接到所述引导路径的呈环圈(13)形式的另一部分。可以此方式获得所述天线的反射系数增益,所述增益在所述天线的传输频带的下限频率限值附近尤其有效。(An antenna (100) emitting radiation from at least one electromagnetic travelling wave propagating along a guide path is designed to reduce reflections of the travelling wave likely to occur at the ends of the guide path. For this purpose, the guide path has at least one section in the form of a spiral section (11, 12) which is connected to another section of the guide path in the form of a loop (13). The reflection coefficient gain of the antenna, which is particularly effective around the lower frequency limit of the transmission band of the antenna, can be obtained in this way.)
