ABSTRACT:
An improved calibration device for an antenna array, or an improved antenna array, is of simple construction. If the total number of antenna elements which are provided for a column is N, where N is a natural number, only N/2 or less coupling devices and/or probes are provided, the number of couplers or probes which are provided are associated with only some of the antenna elements; and a combination network is also provided, via which the coupling devices and/or probes which are provided are connected.
