Example Embodiment
[0051] Example 1
[0052] See Figure 4 , Splice the square modules into a 12*20 antenna array by randomly selecting from the optional set of modules. Each square module has 8*8 antenna units, so 15 modules are required. Calculate the far-field pattern of the array antenna to determine the antenna array layout plan.
[0053] See Figure 5~6 , The figure is a rectangular array, that is, the antenna array in the case of the antenna element spacing λ / 2 (half the working wavelength) of the two main section angle of view. Theoretically, the spacing between the sub-arrays is approximately 1.4 wavelengths, which is greater than the theoretical cell spacing where the grating lobes cannot be scanned by the pattern. The grating lobes will appear after the pattern is scanned, but no grating lobes are found in the calculation results, indicating that this scheme is feasible.
Example Embodiment
[0054] Example 2
[0055] See Figure 7 , Similar to Embodiment 1, the square modules in the optional module set are used to splice into a 16*16 antenna array. Each square module has 4*4 antenna units, so 16 modules are required.
[0056] See Figure 8-9 , The figure is a rectangular array, that is, the antenna array in the case of the antenna element spacing λ / 2 (half the working wavelength) of the two main section angle of view. Theoretically, the spacing between the sub-arrays is approximately 1.4 wavelengths, which is greater than the theoretical cell spacing where the grating lobes cannot be scanned by the pattern. The grating lobes will appear after the pattern is scanned, but no grating lobes are found in the calculation results, indicating that this scheme is feasible.
[0057] To sum up, the present invention proposes a modularized 8-unit L-shaped sub-array application method, selecting 8 8-unit L-shaped sub-arrays, and using a suitable splicing method can achieve more tha...
