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...

Abstract

The invention provides a high-frequency radiation unit and a multi-frequency array antenna, and relates to the field of mobile communication. The high-frequency radiation unit comprises two pairs of cross polarization oscillator arms, wherein the four sequentially-arranged oscillator arms are respectively a first oscillator arm, a second oscillator arm, a third oscillator arm and a fourth oscillator arm, the sizes of the first oscillator arm and the second oscillator arm are same, the size of the third oscillator arm and the fourth oscillator arm are same, the size of the same-polarization first oscillator arm is smaller than the size of the third oscillator arm, the size of the same-polarization second oscillator arm is smaller than the size of the fourth oscillator arm, the sizes of thefirst oscillator arm and the second oscillator arm are same, and the size of the third oscillator arm and the fourth oscillator arm are same. By the high-frequency radiation unit, the cross polarization and the front-to-rear ratio index of the high-frequency radiation unit are improved, and the integral characteristic of medium- and high-frequency radiation of a multi-band antenna is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a high-frequency radiation unit and a multi-frequency array antenna. Background technique [0002] With the rapid development of mobile communication, the performance requirements of the mobile communication system are getting higher and higher, and the performance of the antenna directly affects the overall performance of the mobile communication system, so the design requirements of the antenna are becoming more and more important and stricter. Multi-frequency base station antennas provide the possibility for one antenna to support multiple frequency bands of communication, and have the incomparable advantages of single-frequency antennas, becoming a hot trend in the research and development of base station antennas. [0003] At present, radiation units working in different frequency bands are generally used to form arrays to realize multi-frequency base station antennas. Ho...
