Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] In the prior art, radiation units of different frequency bands are generally used to form arrays to realize multi-frequency base station antennas. However, in multi-frequency array antennas, the sub-array where the high-frequency radiation unit is located is easily affected by the radiation units of its adjacent sub-arrays. Taking the multi-frequency array antenna of high-frequency and low-frequency array as an example, the radiation...
