Calibration apparatus for a switchable antenna array, as well as an associated operating method

Calibration device for a switchable antenna array, distinguished by the following improvements: at least two inputs (19.1, 19.2, 19.3, 19.4) of two or more available inputs (19) of the beam forming network (17; 17') are fed simultaneously and/or jointly and/or in the same phase, and the antenna...

Summary:Calibration device for a switchable antenna array, distinguished by the following improvements: at least two inputs (19.1, 19.2, 19.3, 19.4) of two or more available inputs (19) of the beam forming network (17; 17') are fed simultaneously and/or jointly and/or in the same phase, and the antenna elements (3, 3') have been trimmed in advance in order to produce intermediate lobes (20) or further different azimuth beam directions, such that the individual lobes (16, 116) which are produced when at least two inputs (19.1, 19.2, 19.3, 19.4) are connected can be added with the correct phase.
