Finally, receiving the test signal, and acquiring its corresponding RF characteristics based on the identification tag generated by at least one of the power and phase of each RF amplified signal. This technology tests multiple antenna packaging modules at the same time, thereby shortening the test time.

[0004] The present application solves the problem of judging the influence of electromagnetic waves in various environments and directions on the basic performance of the target packaged antenna by collecting and analyzing the electromagnetic wave parameters in various environments and directions of the target packaged antenna, and then collecting and analyzing the basic performance parameters of the target packaged antenna in various environments and directions, and realizes the feasibility, comprehensiveness and objectivity of the analysis of electromagnetic wave parameters and basic performance parameters in various environments and directions of the target packaged antenna, ensures the reliability and authenticity of the analysis results of electromagnetic wave parameters and basic performance parameters in various environments and directions of the target packaged antenna, and thus provides a reliable basis for the subsequent targeted management of packaged antenna detection.

The specific testing and collection process is as follows: the target packaged antenna is placed on a turntable and placed in a test chamber. When all devices are connected normally and the internal environment of the test chamber meets the test requirements, the electromagnetic wave parameters of the target packaged antenna in various environments and directions are collected when the electromagnetic wave interference source does not emit an electromagnetic wave signal, and are recorded as initial electromagnetic wave parameters; the electromagnetic wave interference source is turned on to emit an electromagnetic wave signal, and the wavelength, frequency and amplitude of the electromagnetic wave are changed one by one according to the set values ​​of the electromagnetic wave, so as to enhance the interference intensity, adjust the environmental control equipment of the test chamber, and gradually rotate the turntable in each environment with an angle increment of 1 degree or less to collect the electromagnetic wave parameters of the target packaged antenna in various environments and directions. After the collection is completed, the test is terminated.

[0029] It should be noted that the turntable is a 360-degree freely rotating turntable controlled by a remote control.

[0030] It should be noted that the environmental control equipment of the test chamber is adjusted to simulate different environmental backgrounds; such as high temperature, freezing and heavy rain.

[0031] It should be noted that a wavelength meter is used to collect the wavelength of electromagnetic waves in various directions of the target packaged antenna in various environments, and an oscilloscope is used to collect the frequency and amplitude of electromagnetic waves in various directions of the target packaged antenna in various environments.

[0032] In this application, by collecting and analyzing various electromagnetic wave parameters of the target packaged antenna in various environments and directions as well as the basic performance parameters of the target packaged antenna in various environments and directions, the feasibility, comprehensiveness and objectivity of the target packaged antenna analysis are achieved, and the reliability and authenticity of the analysis results of various electromagnetic wave parameters of the target packaged antenna in various environments and directions as well as the basic performance parameters of the target packaged antenna in various environments and directions are guaranteed, thereby providing a reliable basis for subsequent packaged antennas to have good performance in practical applications and meet customer needs.

[0033] In a specific example, the analysis obtains the basic evaluation coefficient of electromagnetic waves in each direction of each environment of the target package antenna.

[0051] It should be noted that the impact of electromagnetic waves on the basic performance of the target packaged antenna in all directions and environments is divided into beneficial impact and harmful impact.

[0052] In this application, by simulating different environmental backgrounds, the parameters of frequency response, gain and radiation efficiency of the target packaged antenna in various environments and directions are analyzed, and then it is concluded whether the influence of electromagnetic waves on the basic performance of the target packaged antenna is beneficial or harmful, so as to more accurately understand the changes in the basic performance of the target packaged antenna.
