Claim 0:
1. An arrangement applicable to 4.5G or 5G base station testing, wherein the arrangement comprises:
an antenna arrangement comprising a plurality of antenna elements in a planar arrangement or close to a planar arrangement where a height of an antenna element can be individually tuned in view of other antenna elements,
a test system processor controlling the amplitude and phase of the plurality of antenna elements, and
the plurality of antenna elements are placed in substantially symmetrical fashion in view of a center spot of the antenna arrangement or in view to a center line splitting the antenna arrangement in half,, wherein
the test system processor is configured to divide the plurality of the antenna elements into sub-arrays, where the sub-arrays locate in bands surrounding one another with a substantially mutual center spot, the antenna elements in a single sub-array forming a substantially symmetrical arrangement in view of the center spot or the center line, wherein
the test system processor is configured to control all the antenna elements in the same sub-array with a predetermined amplitude and phase, and
the test system processor is configured to switch on and control dedicated sub-arrays among the whole antenna arrangement, and to switch the rest of the sub-arrays off, applied in a predetermined use frequency, enabling reswitching of the sub-arrays on or off in a given time instant during wideband testing of a 4.5G or 5G base station.
