Description

Debugtable radiating element and antenna

Technical field

The present invention relates to the field of mobile communication antennas, and in particular to a debugtable radiation unit and an antenna.

Background technique

With the development of antenna technology, miniaturization and multi-frequency have become an important development trend of antennas. The high and low frequency nesting scheme is an important method to realize multi-frequency antenna. In the high and low frequency nesting scheme, the antenna isolation index is difficult to implement due to the interaction between high and low frequencies. The currently known multi-polarized antenna isolation adjustment method is typically characterized by adding decoupling loading components around the radiating element and between the radiating elements. These decoupling loading components are located around the radiating element or between the radiating elements. The first current induced between the coupling component and the corresponding radiating element (ie, the induced current generated by the radiating element on the corresponding decoupling component) can most effectively cancel the mutual induction between adjacent radiating elements of the antenna array. The second current.

In the high-low frequency nesting scheme, the well-known isolation debugging method, the low-frequency decoupling debugging component has a great influence on the high-frequency isolation while optimizing the low-frequency isolation, and easily causes the high-frequency isolation to deteriorate; Decoupling and debugging components also have an effect on the isolation of the low frequencies, causing the low frequency isolation to deteriorate. Due to the above phenomenon, the low-frequency high-frequency adjustment is adjusted, the high-frequency low-frequency adjustment is repeated, and the debugging phenomenon is repeated, and the decoupling debugging used is complicated and large in number, which causes debugging time-consuming, poor debugging consistency, and a large amount of decoupling.

Specifically, the antenna 500 includes three configurable radiation units 10 and five high frequency radiation units 20 that are spaced apart as low frequency radiating elements. Two of the high frequency radiating elements 20 are located between two adjacent debuggable radiating elements 10, and the other three high frequency radiating elements 20 are enclosed by the feed balun 124 of the debuggable radiating element 10 and are located in the debuggable radiating element 10.

As such, the third coupling loading portion 166 can be used together with the vibrator arm 1262 as the radiating arm of the second tunable radiating element 10, and also as the decoupling loading component of the antenna 500, which can change the two polarizations of the tunable radiating element 10. Energy coupling between the energy and the energy coupling between the adjacent tunable radiating element 10 and the high frequency radiating element, thereby improving the overall isolation of the antenna 500 without loading the decoupling loading component, minimizing the low frequency decoupling loading component The effect of frequency isolation deterioration ensures good isolation of the high frequency initial state.

At this time, the second coupling load portion 164 having a larger length serves as the radiation arm of the tunable radiation unit 10 together with the vibrator arm 1262, and also serves as a decoupling loading member of the antenna. The coupling loader 16 is equivalent to increase the size of the tunable radiation unit 10, effectively reducing the energy coupling between the tunable radiation unit 10 and the high frequency radiation unit 20 as a unit of low frequency radiation, and improving the high and low frequency Inter-frequency isolation. At the same time, the lengthening of the radiating arms of the tunable radiating element 10 also improves the energy coupling between the high frequency radiating element 20 nested within the tunable radiating element 10 and the high frequency radiating element 20 located outside the tunable unit, and finally The isolation of the high frequency antenna is improved, the use of the high frequency decoupling loading component is reduced, and the influence of the high frequency debugging component on the low frequency isolation is reduced.

As such, the second coupling loading portion 164 and the third coupling loading portion 166 serve both as the coupled oscillator arm 1262 of the debugable radiating element 10 and also as a decoupling loading component of the antenna 700. The second coupling loading portion 164 is equivalent to the third coupling loading portion 166 to increase the size of the debuggable radiating unit 10 as a low frequency radiating unit, effectively reducing the between the debuggable radiating unit 10 and the high frequency radiating unit 20. Energy coupling improves inter-frequency isolation between high and low frequencies.

At the same time, the third coupling loading portion 166 can change the energy coupling between the two polarizations of the second tunable radiation unit 10, reducing the use of high frequency, low frequency decoupling loading components, and reducing the low frequency isolation of the high frequency debugging components. The degree of influence and energy coupling with the adjacent tunable radiating element 10 ultimately improves the antenna low frequency isolation. In addition, the use of high frequency and low frequency decoupling loading components is reduced, the influence of high frequency debugging components on low frequency isolation and the influence of low frequency decoupling loading components on high frequency isolation are reduced, and the decoupling loading components are greatly reduced.
