Problems solved by technology
[0002] In the antenna design stage, antennas with good performance can often be obtained, but in the actual use process, the antennas that performed well before often have poor communication and serious signal loss, and the power consumption of the antenna will also decrease. large fluctuations
[0003] After analysis, it can be determined that the above problems are caused by frequency offset, but how to accurately detect frequency offset is still a problem that is difficult to solve, and the antenna performance and power consumption fluctuations caused by frequency offset cannot be satisfactorily resolved.

Embodiment 1
[0032] The invention provides a frequency offset testing method for equipment antennas, such as figure 1 As shown, the frequency offset testing method includes:
[0033] 11. Build a test platform including a directional coupler for testing the antenna of the equipment, and obtain the path loss level of the communication line including the antenna under test;
[0034] 12. Obtain the frequency offset of the antenna under test during the communication process under each path loss level;
[0035] 13. Replace the antenna under test in the product under test, obtain the communication performance parameters of the product under test installed with different antennas under test, and adjust the structure of the product under test based on the performance parameters.
[0036] In practice, for an ideal omnidirectional antenna, the radiation pattern is uniform over 360 degrees. When the antenna is placed in the product to be tested, the electromagnetic wave radiation pattern generated b...

The invention provides a frequency deviation testing method for an equipment antenna, belonging to the antenna detection field. The frequency deviation testing method comprises the following steps: establishing a testing platform for detecting the equipment antenna, and acquiring path loss grades of communication lines including the tested antenna; acquiring the frequency deviation of the tested antenna under each path loss grade in the communication process; and replacing the tested antenna in a to-be-tested product so as to obtain communication performance parameters of the to-be-tested product provided with different tested antennas, and adjusting the structure of the to-be-tested product based on the performance parameters. According to the frequency deviation testing method, the frequency deviation conditions and the relation between the frequency deviation and the power loss under different path losses are acquired in the antenna communication process of the tested product; and meanwhile, by replacing the tested antenna, the influences caused by a structure and a circuit environment to the frequency deviation resonance of the antenna are obtained in the communication processof the product in which different antennas are mounted, and factors which influence the communication performance of the antennas are judged according to a radiation pattern corresponding to a standard omnidirectional antenna relative to the obtained radiation pattern, thereby finishing the testing of the frequency deviation of the antennas.
Description
technical field [0001] The invention belongs to the field of antenna detection, in particular to a frequency deviation test method for equipment antennas. Background technique [0002] In the antenna design stage, antennas with good performance can often be obtained, but in the actual use process, the antennas that performed well before often have poor communication and serious signal loss, and the power consumption of the antenna will also decrease. Large fluctuations occur.
