Embodiment 1

[0035] Example 1 Plastic vibrator standing wave test system

[0036] The embodiment of the present invention proposes a plastic vibrator standing wave test system, which can be used for plastic vibrator standing wave testing in high and low temperature environments, including a high and low temperature test box 10, a microwave shielding dark box 20, a test tool 30 and a network analyzer 40; The high and low temperature test chamber 10 has an inner cavity capable of accommodating the microwave shielding dark box 20 for accommodating the microwave shielding dark box 20; the microwave shielding dark box 20 is used for accommodating the testing tool 30 and the plastic vibrator M to be tested; The plastic vibrator M to be tested is placed on the test tool 30 for standing wave testing; the network analyzer 40 is used to record standing wave test data.

[0037] The high and low temperature test box 10 is preferably a high and low temperature test box 10 capable of withstanding a weight of...

Embodiment 2

[0055] Example 2 Plastic vibrator standing wave test method

[0056] The embodiment of the present invention also provides a method for performing a standing wave test on a plastic vibrator by using the plastic vibrator standing wave test system, which includes the following steps:

[0057] S1. Place the microwave shielding dark box 20 in the high and low temperature test box 10 so that the distance between the outer wall of the microwave shielding dark box 20 and the inner wall of the high and low temperature test box 10 is not less than 50mm to ensure a good internal circulation during heat exchange;

[0058] S2. Electrically connect the network analyzer 40 and the SMA connector 331 on the test tool 30;

[0059] S3. Place the plastic vibrator M to be tested on the test tool 30, so that the feed pin M1 on the plastic vibrator M to be tested contacts the probe fixed on the impedance matching circuit board 33 of the test tool 30, so that the two are electrically connected;

[0060] S4. P...

Abstract

The embodiment of the invention relates to a plastic oscillator standing wave test system and test method. The plastic oscillator standing wave test system comprises a high-low temperature test box, amicrowave shielding dark box, a test tool and a network analyzer; the high-low temperature test box is provided with an inner cavity capable of accommodating the microwave shielding dark box and is used for accommodating the microwave shielding dark box; the microwave shielding dark box is used for accommodating the test tool; a to-be-tested plastic oscillator is placed on the test tool for standing wave test; and the network analyzer is electrically connected with the test tool and is used for recording standing wave test data. The standing wave testing system can carry out standing wave testing on the plastic oscillator in high and low temperature environments.

Description

Technical field [0001] The invention belongs to the technical field of antenna testing, and specifically relates to a plastic vibrator standing wave testing system and testing method. Background technique [0002] With the advent of the 5G era, antenna oscillators manufactured by traditional sheet metal and die-casting processes are limited by process accuracy and are prone to directional deviation, which can no longer meet antenna performance requirements. The plastic vibrator is molded into a complex 3D three-dimensional shape by injection molding, and then the plastic surface is metalized through a plastic electroplating process. Plastic vibrators are used in 5G mobile communication base stations. While ensuring that the antenna meets the electrical performance of 5G communication, the weight of the product is greatly reduced, dangerous processes are reduced, and costs are saved. This has become a major trend in 5G antennas. [0003] Since plastic vibrators are generally used o...
