Problems solved by technology

For the 5G frequency band, due to its large frequency band span, in order to fully cover the 5G frequency band, the traditional broadband base station antenna can only achieve this goal by increasing the antenna size, but increasing the antenna size has nothing to do with saving the base station Site resources have conflicting purposes

specific Embodiment

[0036] Such as Figure 1-6As shown, a 5G broadband dual-polarized base station antenna based on a multimode resonant structure includes a main radiating unit (1002), a first resonant structure (1001), two feeding baluns (1003) (1004) and a metal reflector (1005); The main radiation unit (1002) has two resonant structures (10021) (10022) for adjusting different resonant points, wherein the resonant structure (10021) controls the resonant point at the high frequency, and the resonant structure (10022) Control the resonance point at the low frequency, and at the same time, there are four via holes (1100) (1101) (1102) (1103) on the main radiation unit (1002) respectively connected to the feed balun (1003) (1004); The first resonant structure (1001) is located above the main radiating unit (1002), the first resonant structure (1001) controls the position of the third resonant point, and there are four via holes (1200) on the first resonant structure (1001) ) (1201) (1202) (1203) ...

Abstract

The invention discloses a 5G broadband dual-polarization base station antenna with a multimode resonant structure. The 5G broadband dual-polarization base station antenna comprises a first resonant structure, a main radiation unit, a feed balun group and a metal reflecting plate, wherein the feed balun group is arranged on the metal reflecting plate, the main radiation unit is arranged on the first feed balun and the second feed balun, and the first resonant structure is arranged on the main radiation unit; the main radiation unit comprises a second resonance structure and a third resonance structure, the first resonance structure is used for controlling a resonance point at a high frequency, and the third resonance structure is used for controlling a resonance point at a low frequency; and the feed balun group is used for providing balance current for the main radiation unit and the first resonant structure. The purpose that the resonance points are adjustable is achieved by changing the structural parameters of the antenna, the first resonance structure is loaded above the antenna to generate the third resonance point, and under the combined action of the three resonance points, the designed base station antenna achieves the broadband characteristic.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a 5G broadband dual-polarized base station antenna with a multi-mode resonance structure. Background technique [0002] With the advent of the 5G era, the Ministry of Industry and Information Technology of my country has allocated new and higher frequency bands for 5G development and use for operators, and the 5G frequency bands allocated by each operator are different. Among them, China Mobile's 5G frequency band is 2.515-2.675GHz and 4.8-4.9GHz; China Telecom's 5G frequency band is 3.4-3.5GHz; China Unicom's 5G frequency band is 3.5-3.6GHz. In order to save the site resources of the base station, how to use one antenna to cover all the above-mentioned 5G frequency bands becomes the key to saving the site resources of the base station. For the 5G frequency band, due to its large frequency band span, in order to fully cover the 5G frequency band, the traditional broadband base ...
