Abstract
A testing system and a testing method with multiple antennas are provided. The system comprises an anechoic chamber for containing a device under test, at least two feed antennas, a movable shaped reflector, and a reflector positioner rotationally coupled to the shaped reflector. The reflector positioner provides a rotation mechanism that rotates the shaped reflector and directs its focal point towards a field generated by each of the at least two feed antennas.
Claims21
A testing system with multi antennas comprising:
- an anechoic chamber for containing a device under test,
- at least two feed antennas,
- a movable shaped reflector, and
- a reflector positioner rotationally coupled to the shaped reflector,
- wherein the reflector positioner provides a rotation mechanism that rotates the shaped reflector and directs a focal point of the shaped reflector towards each of the at least two feed antennas, and
- wherein the rotation mechanism provided by the reflector positioner allows for rotational movement of the shaped reflector, whereby the shaped reflector rotates along an axis orthogonal to a plane wave front radiated by each of the at least two feed antennas.
