WIPO Patent Application WO/2021/000476
Kind Code:
A1
Abstract:
Provided is a multi-frequency narrow beam antenna with a good convergence and a high gain. The multi-frequency narrow beam antenna comprises a first high-frequency column, a second high-frequency column, a third high-frequency column, and a fourth high-frequency column respectively formed by a plurality of first high-frequency radiation units, second high-frequency radiation units, third high-frequency radiation units, and fourth high-frequency radiation units correspondingly located along a first reference line, a second reference line, a third reference line, and a fourth reference line; and a first low-frequency column and a second low-frequency column respectively formed by a plurality of first low-frequency radiation units and second low-frequency radiation units correspondingly located along the first reference line and the third reference line, wherein the first reference line, the second reference line, the third reference line and the fourth reference line are sequentially arranged at intervals and are parallel to each other, the first high-frequency column and the second high-frequency column form a first high-frequency narrow beam array, the third high-frequency column and the fourth high-frequency column form a second high-frequency narrow beam array, the first low-frequency column and the second low-frequency column form a low-frequency narrow beam array, and the low-frequency narrow beam array comprises first low-frequency radiation units and second low-frequency radiation units adjacent to each other in a pairwise manner, and second low-frequency radiation units that are not adjacent to the first low-frequency radiation units, and/or first low-frequency radiation units that are not adjacent to the second low-frequency radiation units.
