Abstract
A calibration device for a switchable antenna array, distinguished by the following improvements provides at least two inputs of two or more available inputs of the beam forming network fed simultaneously and/or jointly and/or in the same phase. The antenna elements have been trimmed in advance in order to produce intermediate lobes or further different azimuth beam directions, such that the individual lobes which are produced when at least two inputs are connected can be added with the correct phase.
