Over-the-air test system and method for testing a device under test

A method for testing a device under test with an over-the-air test system for testing a device under test in a wireless communication environment, comprising the following steps:

• providing a device under test;
• providing a signal processing unit connected to a measurement antenna having a radiation pattern with a main lobe;
• providing a reflector that is positioned in a signal path between said device under test and said measurement antenna;
• transmitting a first signal via said device under test or said measurement antenna, said first signal being reflected by said reflector;
• receiving said first signal transmitted by said measurement antenna or said device under test under a first incident angle;
• controlling said measurement antenna such that the direction of said main lobe is varied;
• transmitting a second signal via said device under test or said measurement antenna, said second signal being reflected by said reflector;
• and
• receiving said second signal transmitted by said measurement antenna or said device under test under a second incident angle.
