Classification: CPC G  H | IPC G  H

Claim 14:
15. A method applicable to 4.5G or 5G base station testing, wherein the method comprises the steps of:
arranging planarly or close to a planar arrangement a plurality of antenna elements into an antenna arrangement where a height of an antenna element can be individually tuned in view of other antenna elements,
controlling the amplitude and phase of the plurality of antenna elements by a test system processor, and
placing the plurality of antenna elements 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 method further comprises the steps of
dividing, by the test system processor, 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
controlling, by the test system processor, all the antenna elements in the same sub-array with a predetermined amplitude and phase, and
switching on and controlling, by the test system processor, dedicated sub-arrays among the whole antenna arrangement, and switching 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.
