Specifically, the number of transmitting unit sub-arrays can be set according to actual antenna gain requirements. The antenna array shown in FIG. 1 includes two transmitting unit sub-arrays, but this embodiment is not limited thereto. The transmitting unit sub-array includes a sub-array 01 and a sub-array 02; the two transmitting unit sub-arrays are arranged in parallel, and the high-frequency vibrator a1 in the sub-array 01 and the high-frequency vibrator a2 in the sub-array 02 are misaligned in the vertical direction of the central axis MN, that is, adjacent The high-frequency vibrator a1 and the high-frequency vibrator a2 in the sub-array 01 and sub-array 02 are arranged alternately. There are at least two high-frequency oscillators a1 between the low-frequency oscillators b1 in the sub-array 01, and the same arrangement is adopted for the sub-array 02; the low-frequency oscillator b1 in the sub-array 01 and the low-frequency oscillator b2 in the sub-array 02 are not on the same vertical line Above, the low-frequency vibrator b1 and the low-frequency vibrator b2 in the adjacent sub-array 01 and sub-array 02 are arranged in a triangular grid.

In practical applications, a high-frequency vibrator may or may not be nested within the caliber of the low-frequency vibrator in the antenna array. In the antenna array, a high-frequency vibrator can be embedded in the aperture of all low-frequency oscillators, or a high-frequency oscillator can be nested in the aperture of some low-frequency oscillators, or no high-frequency oscillator can be nested in the aperture of all low-frequency oscillators; In each sub-array, a high-frequency vibrator can be embedded in the aperture of all low-frequency oscillators, or a high-frequency oscillator can be nested in the aperture of some low-frequency oscillators, or no high-frequency oscillator can be nested in the aperture of all low-frequency oscillators. frequency vibrator.

Because the installation area of the vibrator in the antenna structure is limited, the addition of the low-frequency vibrator must be simple and convenient, and the installation space can be fully utilized. Therefore, sub-arrays of emitting units can be arranged in sub-arrays of multiple columns of high-frequency oscillators. In the antenna array, two adjacent columns of sub-arrays are selected, and the low-frequency oscillators are nested with high-frequency oscillators and arranged in a triangular grid to form two columns of transmitting unit sub-arrays.
