Abstract:
1. An antenna configuration which has a first antenna arm and a second antenna arm, wherein each of the two antenna arms is made of electrically conductive material and has a first end and a second end and has a longitudinal direction which runs from the first end to the second end, wherein the two first ends are arranged at a first distance from one another and adjacent to one another and are in each case intended and designed for electrically conductive connection to a terminal of a signal sink or a signal source, wherein the two second ends are arranged at a second distance from one another and remote from one another, said second distance being greater than the first distance, and wherein the two longitudinal directions of the two antenna arms enclose an acute opening angle (a) with one another, and wherein the acute opening angle has a value of between 15° and 90°, wherein at least one coupling web is provided in order to electromagnetically couple the two antenna arms, wherein the coupling web is made of electrically conductive material and extends at least over a region lying between the two antenna arms and is electrically isolated from the two antenna arms, the antenna configuration satisfying at least one of: (a) wherein the at least one coupling web has the form of a wide plate, (b) wherein the at least one coupling web extends over the region lying between the two antenna arms and beyond the two antenna arms, and (c) wherein the two antenna arms, with respect to a substrate for the two antenna arms, are provided together on a first side surface of the substrate and wherein the at least one coupling web is provided on the opposite, second side surface of the substrate.
