Embodiment 1

[0046] In Embodiment 1, the first plate surface is the upper surface of the dielectric substrate, and the second plate surface is the lower surface of the dielectric substrate.

[0047] like figure 1 As shown, a three-frequency common-aperture fusion antenna includes a low-frequency unit 1, a non-uniform surface 2, an intermediate frequency unit 3, a high-frequency unit 4, and a reflector 5 from top to bottom. The working frequency band of the low-frequency unit is 690- 960MHz, the working frequency band of the intermediate frequency unit is 1700MHz-2200MHz, and the working frequency band of the high frequency unit is 4800MHz-5000MHz.

[0048] The high-frequency unit 4 is located above the reflector 5, and the distance between the two is 19 mm in this embodiment. The intermediate frequency unit is located above the high frequency unit. In this embodiment, the distance between the two is 17mm. The low frequency unit is located above the intermediate frequency unit. In this emb...

Abstract

The invention discloses a three-frequency common-caliber fusion antenna, a fusion method and communication equipment. The three-frequency common-caliber fusion antenna sequentially comprises a low-frequency unit, a non-uniform surface, an intermediate-frequency unit, a low-frequency unit and a reflecting plate from top to bottom; the low-frequency unit includes a + / -45 degree dual-polarized planar oscillator antenna and comprises low-frequency radiation arms, a low-frequency dielectric substrate, a low-frequency feeder line structure, a low-frequency coaxial line, resonant structures and choke flow structures, the resonant structures are arranged between the adjacent low-frequency radiation arms, one ends, far away from the central point of the low-frequency dielectric substrate, of the low-frequency radiation arms are disconnected, and the choke flow structures are arranged at the disconnected positions of the low-frequency radiation arms. According to the antenna, the coupling problem between different frequency band units is solved by adopting a mode of combining a choke structure and a non-uniform surface, and the antenna can normally work in different frequency bands.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a triple-frequency common-aperture fusion antenna, a fusion method and communication equipment. Background technique [0002] The continuous development of mobile communication technology has brought great changes to our life. The antenna is an important part of the communication system, and its performance directly affects the performance and communication quality of the wireless communication system. With the increase of communication demand, the frequency band of mobile communication continues to expand, and the communication standard is constantly changing. In the Sub 6GHz frequency band, the broadband coverage demand from 690-5000MHz has been formed, and various communication systems coexist. Currently, the communication systems in use in my country are: 2G, 3G, 4G, and 5G communication standards, among which the antennas of the standard before 4G are mostly arranged in a...
