Abstract
An antenna array for at least one of generating and receiving a plane wave in a certain distance is described, the antenna array comprising a plurality of antennas which are movable with respect to each other. The antenna array is configured such that plane waves are at least one of generated and received in the near field of the antenna array. Further, a test system and a method for testing a device under test are described.
Claims18
An antenna array for generating and/or receiving a plane wave in a certain distance, said antenna array comprising a plurality of antennas which are movable with respect to each other, said antenna array being configured such that plane waves are at least one of generated and received in the near field of said antenna array, said antenna array being configured to adapt the plane wave zone distance of said antenna array by adjusting the distances and/or spaces of said antennas with respect to each other.
An antenna array comprising a plurality of antennas which are located in at least two different layers, said antennas of each layer being of the same kind of antenna, said different layers each comprising different types of antennas, said antenna array being configured to adapt the plane wave zone distance of said antenna array by adjusting the distances and/or spaces of said antennas with respect to each other.
A method for testing a device under test, comprising:
- using one of an antenna array for testing said device under test, said antenna array selected from the grouped consisting of:
- an antenna array comprising a plurality of antennas which are movable with respect to each other, said antenna array being configured such that plane waves are at least one of generated and received in the near field of said antenna array;
- an antenna array comprising a plurality of antennas which are located in at least two different layers, said antennas of each layer being of the same kind of antenna, said different layers each comprising different types of antennas;
- and
- adapting the plane wave zone distance of said antenna array by adjusting the distances and/or spaces of said antennas with respect to each other.
