Antenna testing device

Technical Field

The utility model discloses be applied to antenna test technical field, in particular to antenna testing arrangement.

Background

The compact range measurement technology is a measurement mode provided for solving the problems of difficult alignment, poor confidentiality, high requirement of measurement on weather conditions and the like in outdoor far-field measurement. The condition for measuring the far-field antenna is to make the maximum phase difference of the antenna surface reach 22.5 degrees, namely to make the minimum distance of the antenna to be measured larger than a critical value. This distance increases as the operating frequency of the antenna increases. The compact field measurement technology is a solution to high frequency antenna measurement proposed in this background.

It can be seen by above-mentioned scheme that the feed source, reflection module, rotation module and visual detection module all set up the inside of shielded cell, the feed source to reflection module sends the detected signal, and this detected signal is in reflection under the effect of reflection module is to the product that awaits measuring tests. The shielding box plays a role in isolating external base station signals and external interference signals in the testing process, an interference-free testing environment is provided, the product can be driven to rotate under the action of the rotating module, a plurality of parts and a plurality of angles of the product are tested, the visual detection module is used for photographing and detecting the testing state of the product, the testing reliability is greatly improved, and the testing result is more accurate.

Furthermore, the reflection module includes support frame and reflecting plate, the support frame is fixed the lateral part of shielded cell, the reflecting plate with the feed source is all fixed on the support frame, the transmitting terminal of feed source with the reflecting plate sets up relatively. Therefore, the reflecting plate reflects the detection signal emitted by the feed source to the product, so that the product is tested.

Further, rotatory module includes supporting seat, Y axle rotary platform, Z axle revolving stage and location carrier, the supporting seat sets up on the bottom plate of shielded cell, Z axle revolving stage sets up on the supporting seat, Y axle rotary platform sets up the expansion end of Z axle revolving stage, the location carrier sets up the expansion end of Y axle rotary platform, the product setting of awaiting measuring is in on the location carrier. It can be seen from this that, the product setting of awaiting measuring plays the fixed action to the product on the location carrier, avoids appearing the off normal or problem that drops at rotatory in-process, through the drive of Z axle revolving stage, the product that awaits measuring can rotate certain angle round the Z axle, through the drive of Y axle rotary platform, the product that awaits measuring can rotate certain angle round the Y axle, is convenient for test a plurality of positions, a plurality of angle of product.

Furthermore, the visual inspection module comprises an industrial camera and an LED light source, the industrial camera and the LED light source are arranged at the top of the shielding box, and the shooting end of the industrial camera is arranged opposite to a product to be tested. Therefore, the LED light source provides enough brightness for the interior of the shielding box, and the industrial camera is used for photographing and detecting the testing state of the product.

Furthermore, the shielding case includes box and a plurality of inhale the ripples bubble cotton, a plurality of inhale the ripples bubble cotton all set up on the inner wall of box. Therefore, the wave-absorbing foam can absorb or greatly reduce the electromagnetic wave energy received by the surface of the wave-absorbing foam, so that the interference of the electromagnetic wave is reduced.
