Abstract
A multi-panel base station test system includes a base station radio unit configured with a plurality of antenna panels positioned at a first end of a test chamber of the multi-panel base station test system. The multi-panel base station test system includes a plurality of test antennas positioned at a second end of the test chamber opposing the first end. The multi-panel base station test system includes a microwave lens positioned between the plurality of antenna panels and the plurality of test antennas in the test chamber. The microwave lens is configured to focus respective beams transmitted from each of the plurality of antenna panels toward respective focal points associated with each of the plurality of test antennas based on steering of the plurality of antenna panels.
Claims20
A system, comprising:
- a base station radio unit configured to transmit a plurality of beams towards a plurality of far-field focal points;
- a plurality of test antennas associated with a plurality of near-field focal points,
- a first test antenna associated with a first set of near-field focal points of the plurality of the near-field focal points, and

- a microwave lens configured to focus the plurality of beams towards the plurality of near-field focal points,
- wherein the microwave lens is configured to focus a first beam, of the plurality of beams, towards the first set of near-field focal points in a first position, and
- wherein the microwave lens is configured to focus a second beam, of the plurality of beams, towards the second set of near-field focal points based on steering to a second position;
- and
- a testing device in communication with the plurality of test antennas and configured to execute one or more tests, on the plurality of beams received by the plurality of test antennas, to determine a performance of the base station radio unit.
A method, comprising:
- transmitting, by a base station, a plurality of radio frequency (RF) signals to a plurality of far-field focal points,
- a first test antenna associated with a first set of near-field focal points of a plurality of the near-field focal points, and
- a second test antenna associated with a second set of near-field focal points of the plurality of the near-field focal points;
- focusing, by a microwave lens or a microwave reflector and based on transmitting the plurality of RF signals, the plurality of RF signals towards the plurality of near-field focal points,
- wherein the microwave lens is configured to focus a first RF signal, of the plurality of RF signals, towards the first set of near-field focal points in a first position, and
- wherein the microwave lens is configured to focus a second RF signal, of the plurality of RF signals, towards the second set of near-field focal points based on steering to a second position;
- receiving, by a plurality of test antennas, associated with the plurality of near-field focal points, and based on focusing the plurality of RF signals, the plurality of RF signals;
- sending, by the plurality of test antennas and based on receiving the plurality of RF signals, the plurality of RF signals to a testing device;
- and
- performing, by the testing device, one or more measurements, on the plurality of RF signals, to determine a performance of the base station.
A system, comprising:
- a radio unit configured to transmit a plurality of radio frequency (RF) signals to a far-field focal point;
- a microwave lens, or a microwave reflector, configured to focus the plurality of RF signals towards a near-field focal point,
- wherein the microwave lens is configured to focus the plurality of RF signals towards the near-field focal point in a first position, and
- wherein the microwave lens is configured to focus a second plurality of RF signals towards another near-field focal point based on steering to a second position;
- and
- a plurality of test antennas associated with the near-field focal point and configured to:
