宽带的全向的天线
摘要：
一种改进的天线，其具有以下特征：包括一个单极辐射器(11)，所述单极辐射器是垂直极化的；包括至少两个水平极化的并且绕中心轴线(Z)在圆周方向上彼此错开的辐射器；包括一个反射器(1)，在该反射器之前隔开间距(A)地设置所述至少两个水平极化的辐射器以及所述单极辐射器(11)；所述至少两个水平极化的辐射器分别包括一个维瓦尔第天线(5)；所述维瓦尔第天线(5)具有构成馈电平面(123′)的中心面和/或馈电面(123)，在所述馈电平面中构成或设置导电层(27、127)，所述导电层具有在辐射方向上扩宽的槽线(29′)；所述馈电平面(123′)相对于所述反射器(1)隔开间距(A)地设置；以及所述导电层(27、127)在构成有至少一个弧形的和/或折弯的延长部(27a、127a)的情况下从所述馈电平面(123′)伸出。
摘要（英）：

The invention relates to an improved antenna which is distinguished by, among other things, the following features: the antenna has a monopole radiator (11), which is vertically polarized; the antenna has at least two horizontally polarized radiators, which lie offset from each other in a circumferential direction about a central axis (Z); the antenna has a reflector (1), in front of which the at least two horizontally polarized radiators and the monopole radiator (11) are arranged at a distance (A); the at least two horizontally polarized radiators each comprise a Vivaldi antenna (5); the Vivaldi antennas (5) have a central and/or feeding surface (123), which forms a feeding plane (123′), in which an electrically conductive layer (27, 127) having slot lines (29′) that widen in a radiation direction is formed or provided, —the feeding plane (123′) is arranged at a distance (A) from the reflector (1); and the electrically conductive layer (27, 127) is led out of the feeding plane (123′), wherein at least one arcuate and/or bent extension (27a, 127a) is formed.
