Embodiment 1

[0041] In order to improve the test efficiency of the total radiated power (TPR) of the array antenna of the 5G active antenna system, an embodiment of the present invention provides a method for measuring the total radiated power of the array antenna.

[0042] 3GPP stipulates that the active antenna system base station is divided into two types of 1-O and 2-O equipment. The difference between the two is that the operating frequency is different, but the overall structure is almost the same. The 1-O and 2-O equipment have been recorded before. I won't go into details here. 3GPP stipulates that the radio frequency test for 1-O and 2-O equipment must use the radiation test method, that is, OTA test.

[0043] Generally speaking, a darkroom environment is required for OTA testing. At present, there are mainly three types of darkroom environments, namely far-field, compact-field and near-field darkrooms. Due to the limited test items of the near-field darkroom, 3GPP is still in t...

Embodiment 2

[0079] On the basis of the above-mentioned embodiments, the embodiment of the present invention will further describe the method for testing the total radiated power of the array antenna in detail by taking the independent partition mode as an example.

[0080] Figure 6 It is an embodiment of calculating the total radiated power TRP of an array antenna in an independent partition manner, wherein the array antenna is divided into four antenna sub-arrays, namely A1, A2, A3 and A4. Maximum dimension D in the vertical direction z,max is the size corresponding to the antenna sub-arrays A1 and A2, and the maximum size D in the horizontal direction y,max is the size corresponding to the antenna sub-array A3. The Rayleigh resolution in the y- and z-directions and the resulting sampling points are given by the dimension D y,max and D z,max Decide.

[0081] see Figure 7Shown is the flow chart of the test method for calculating TRP using the independent partition method, as follo...

example 1

[0110] In this example, the size of the array antenna is 8λ×8λ, where λ represents the wavelength. The array antenna to be tested is divided into two antenna sub-arrays, specifically composed of two identical antenna sub-arrays on the left and right, and the TRP sampling is performed in the angle space.

[0111] S701. Divide the entire array antenna to be tested into N areas to form N antenna sub-arrays, where N is greater than or equal to 2.

[0112] Specifically, the 8λ×8λ array antenna to be tested is divided into two 4λ×8λ sub-arrays with the same left and right sides, and N is determined to be 2.

[0113] S702. Determine the Rayleigh resolution according to the maximum size of the N antenna subarrays, and determine the sampling interval according to the Rayleigh resolution.

[0114] Specifically, since the full-array antenna consists of two identical antenna sub-arrays on the left and right, the antenna sub-array corresponds to the maximum size D in the y direction and t...
