The invention relates to an improved antenna which is distinguished by, among other things, the following features: the antenna has a monopole radiator (), 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 (), in front of which the at least two horizontally polarized radiators and the monopole radiator () are arranged at a distance (A); the at least two horizontally polarized radiators each comprise a Vivaldi antenna (); the Vivaldi antennas () have a central and/or feeding surface (), which forms a feeding plane ('), in which an electrically conductive layer () having slot lines (&#x2032;) that widen in a radiation direction is formed or provided, &#x2014;the feeding plane (&#x2032;) is arranged at a distance (A) from the reflector (); and the electrically conductive layer () is led out of the feeding plane (&#x2032;), wherein at least one arcuate and/or bent extension () is formed.

Broadband omnidirectional antenna

An improved nondirectional radiofrequency power divider is characterized by the following features: &#x2014;having an outer conductor () and/or outer conductor housing ('), with a first inner conductor (), wherein the first inner conductor () runs in the outer conductor () or in the outer conductor housing (&#x2032;), &#x2014;with a second inner conductor (), wherein the second inner conductor () runs in the space () which is formed between the first inner conductor () and the outer conductor () or the outer conductor housing (&#x2032;), &#x2014;the second inner conductor () is electrically connected to a branch line running away therefrom or is provided therewith, the second inner conductor () is relatively adjustable and/or positionable in terms of the distance of said second inner conductor from the first inner conductor () and/or in terms of the distance of said inner conductor from the outer conductor () or from the outer conductor housing (&#x2032;) so as to effect a variable power distribution.
