Abstract
The invention relates to an antenna far-field measuring system which comprises a directional antenna, a first light generator, a second light generator, a fixing device, a bearing device and a microwave darkroom. The first light generator is used for emitting a first plane light beam. The second light generator is used for emitting a second plane light beam. The fixing device fixes the first light generator and the second light generator on the side of the directional antenna, and the first plane light beam and the second plane light beam intersect at a first straight line. When the object to be measured is arranged on the object to be measured bearing device, the first plane light beam and the second plane light beam project a cross shape on the object to be measured, so that the directivity antenna and the measured object to be measured can be aligned to each other by utilizing the cross shape.
Description
Technical Field
The present invention relates to a measuring system, and more particularly, to an antenna module with an alignment function and an antenna far-field measuring system including the antenna module.
Background technology
Referring to fig. 1, a conventional antenna far-field measurement darkroom system includes a darkroom 11, a standard antenna 12 and a turntable 13.
The standard antenna 12 is fixed to the side wall 111 of the darkroom 11. The object 14 is placed on the turntable 13, but this technique has the disadvantage that the object 14 is not aligned with the standard antenna 12 exactly when the measurement is not determined, especially when the distance between the standard antenna 12 and the device 14 is far from the near field measurement when the measurement is far field, and a slight position deviation of the device 14 mounted on the turntable 13 may cause a significant error in the final measurement result. In order to solve the disadvantage, the present invention proposes an antenna module having an alignment function (fig. 2) to replace the conventional standard antenna 12 without the alignment function.

The first light generator is used for emitting a first plane light beam. The second light generator is used for emitting a second plane light beam. The fixing device fixes the first light generator and the second light generator on the side of the directional antenna, and the first plane light beam and the second plane light beam intersect at a first straight line.
Preferably, the main beam of the directional antenna propagates along a first straight line.
Preferably, the first and second planar beams are laser beams.
Preferably, the directional antenna is a horn antenna.
Preferably, the directional antenna is an array antenna.
The invention relates to an antenna far-field measuring system, which comprises a directional antenna, a first light generator, a second light generator, a fixing device, a bearing device and a microwave darkroom.
The first light generator is used for emitting a first plane light beam. The second light generator is used for emitting a second plane light beam. The fixing device fixes the first light generator and the second light generator on the side of the directional antenna, and the first plane light beam and the second plane light beam intersect at a first straight line. The bearing device is used for bearing an object to be lateral, and when the object to be lateral is arranged on the bearing device, the first plane light beam and the second plane light beam project a cross shape on the object to be lateral. The bearing device, the first light generator, the second light generator and the fixing device are arranged in the microwave darkroom.
Preferably, the main beam of the directional antenna points to an intersection point of the cross shape, and the intersection point overlaps with the geometric center of the object to be measured.
Preferably, the first and second planar beams are laser beams
Preferably, the directional antenna is a horn antenna or an array antenna.
The effect of the invention is: the first light generator and the second light generator are fixed on the side of the directional antenna, so that the position of the device to be tested can be adjusted by utilizing the cross-shaped intersection point projected by the first plane light beam and the second plane light beam on the object to be tested, the device to be tested can be aligned to the main beam of the directional antenna, and the measurement error caused by the fact that the device to be tested in the prior art is not aligned to the directional antenna is avoided.

The first light generator 3 is configured to emit a first planar light beam 6. The second light generator 4 is arranged to emit a second planar light beam 7. The fixing device 5 fixes the first light generator 3 and the second light generator 4 at the side of the directional antenna 2, and the first planar beam 6 and the second planar beam 7 intersect at a first straight line 8. The carrying device 9 can be a turntable or a robot arm, and is used for carrying the object 20 to be held, such as a mobile phone.
In the preferred embodiment, the first planar beam 6 and the second planar beam 7 are both laser beams, the directional antenna 2 is a horn antenna, the main beam 21 of the directional antenna propagates along the first straight line 8, and when the object 20 to be inspected is disposed on the carrying device 9, the first planar beam 6 and the second planar beam 7 project a cross shape on the object 20 to be inspected, the main beam of the directional antenna 2 points to the intersection point 67 of the cross shape, and the intersection point 67 overlaps with the geometric center of the object 20 to be inspected.
Referring to fig. 4, an embodiment of the directional antenna 2 is described in which a planar array antenna is used instead of a horn antenna.
The invention has the beneficial effects that: the first light generator 3 and the second light generator 4 are fixed on the side of the directional antenna 2, so that the position of the device under test 20 can be adjusted by using the cross-shaped intersection point 67 projected by the first planar light beam 6 and the second planar light beam 7 on the object under test 20, so that the device under test 20 can be aligned to the main beam 21 of the directional antenna 2, thereby avoiding the measurement error caused by the prior art that the device under test 20 is not aligned to the directional antenna 2.
The above description is only an example of the present invention, and is not intended to limit the scope of the present invention.
