Abstract
An antenna apparatus for calibrating one or more of a plurality of antenna elements of an antenna array using one or more probes is disclosed. The apparatus includes an upconverter and/or downconverter (UDC) circuit and a calibration arrangement that includes a switching circuit. The switching circuit is configured to enable operation of the UDC in a first mode or in a second mode. When the UDC is in the first mode, the one or more probes are electrically disconnected from the UDC circuit and the UDC may be connected to at least one of the antenna elements. When the UDC is in the second mode, at least one of the one or more probes is connected to the UDC circuit.
