Abstract
The present disclosure generally relates to an anechoic chamber for testing a device under test over-the-air, a system, and a method. The anechoic chamber includes at least one reflecting surface being configured to variably manipulate in a defined manner at least one reflection process of at least one electromagnetic wave usable for testing the device under test.

An anechoic chamber for testing a device under test over-the-air, the anechoic chamber comprising at least one reflecting surface being coupled to a control circuit and being configured to variably manipulate in a defined manner at least one reflection process of at least one electromagnetic wave usable for testing the device under test, wherein a variable manipulation of the reflection process is caused by at least one property of the at least one reflecting surface being variably controlled in-field by a control signal of the control circuit, and wherein at least a direction of the at least one electromagnetic wave is manipulatable based on the variable manipulation of the reflection process.
A system for testing a device under test over-the-air, the system comprising the anechoic chamber and a device under test,
- wherein the anechoic chamber comprises at least one reflecting surface being coupled to a control circuit and being configured to variably manipulate in a defined manner at least one reflection process of at least one electromagnetic wave usable for testing the device under test,
- wherein the anechoic chamber comprises a testing area,
- wherein the system has at least one transmission antenna element and/or at least one reception antenna element, and
- wherein the device under test and the at least one reflecting surface are arranged within the testing area, and
- wherein a variable manipulation of the reflection process is caused by at least one property of the at least one reflecting surface being variably controlled in-field by a control signal of the control circuit, and wherein at least a direction of the at least one electromagnetic wave is manipulatable based on the variable manipulation of the reflection process.
A method of testing a device under test over-the-air, the method comprising:
- providing an anechoic chamber having a testing area with the device under test and at least one reflecting surface arranged therein and being coupled to a control circuit, the anechoic chamber comprising at least one transmission antenna element and/or at least one reception antenna element,
- emitting at least one electromagnetic wave,
- variably manipulating, using the at least one reflecting surface, at least one reflection process of the at least one electromagnetic wave in a defined manner, wherein a variable manipulation of the reflection process is caused by at least one property of the at least one reflecting surface being variably controlled in-field by a control signal of the control circuit, and wherein at least a direction of the at least one electromagnetic wave is manipulatable based on the variable manipulation of the reflection process, and
- receiving the at least one electromagnetic wave reflected by the at least one reflecting surface.
