Detailed Description
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides an antenna module, which includes a circuit board, at least two antenna radiators 10, and at least one lumped element 20.
The operating frequencies of at least two antenna radiators 10 are different, for example, in a specific embodiment, the number of the antenna radiators 10 is two, where the operating frequency of one antenna radiator 10 is 617 and 2690MHz, and the operating frequency of the other antenna radiator 10 is 5150 and 5875 MHz.
At least one lumped element 20 is disposed on the circuit board, in a specific example, a lumped element disposition position is reserved on the circuit board, and the lumped element 20 matched with the antenna radiator 10 is disposed on the reserved lumped element disposition position, of course, when a certain antenna radiator 10 does not need to match the lumped element 20, the lumped element 20 may not be matched, and at this time, the lumped element disposition position is still reserved on the circuit board, so that the development cycle and the debugging cycle can be shortened.
At least two feed points 30 and at least one feed point 40 are provided on the circuit board, each antenna radiator 10 being connected to at least one feed point 30, and each feed point 40 being connected to one antenna radiator 10.
A lumped element 20 is disposed between the antenna radiator 10 and the feeding point 30 connected to the antenna radiator 10, or a lumped element 20 is disposed between the antenna radiator 10 and the feeding point 40 connected to the antenna radiator 10.
Lumped element 20 refers to an element or component of an actual circuit whose physical dimensions are much smaller than the wavelength of the electromagnetic wave signal passing through it. The lumped element 20 may be, for example, a capacitor 21 or an inductor 22. The reason why the capacitor 21 or the inductor 22 enables tuning the performance of the antenna radiator 10 is that: the capacitor 21 and the inductor 22 both have different degrees of influence on the performance of the antenna radiator 10 at the high-band operating frequency and the antenna radiator 10 at the low-band operating frequency, and selecting an appropriate capacitor 21 or inductor 22 can cause the antenna radiator 10 and the feed point 30 connected to the antenna radiator 10 to be in an open or short circuit state, and can cause the antenna radiator 10 and the feed point 40 connected to the antenna radiator 10 to be in an open or short circuit state, thereby reducing the mutual influence between the antenna radiators 10.
Specifically, as for the inductor 22, the inductor 22 is provided between the antenna radiator 10 and the feeding point connected to the antenna radiator 10 based on X ═ j ω L, ω ═ 2 pi f, (where X is a reactance value, L is an inductance value, and f is a frequency), the influence on the performance of the antenna radiator 10 at a low frequency operating frequency is small, and the influence on the performance of the antenna radiator 10 at a high frequency operating frequency is large; the inductor 22 is provided between the antenna radiator 10 and a feed point connected to the antenna radiator 10, and has a large influence on the performance of the antenna radiator 10 at a low frequency operating frequency and a small influence on the performance of the antenna radiator 10 at a high frequency operating frequency.
Specifically, as for the capacitor 21, the capacitor 21 is provided between the antenna radiator 10 and the feed point connected to the antenna radiator 10 based on X ═ 1/(j ω C), ω ═ 2 π f, (where X is a reactance value, C is a capacitance value, and f is a frequency), and the influence on the performance of the antenna radiator 10 at a low frequency operating frequency is large, and the influence on the performance of the antenna radiator 10 at a high frequency operating frequency is small; the capacitor 21 is provided between the antenna radiator 10 and the feed point connected to the antenna radiator 10, and has a small influence on the performance of the antenna radiator 10 at the low frequency operating frequency and a large influence on the performance of the antenna radiator 10 at the high frequency operating frequency.

By arranging the lumped element 20 between the antenna radiator 10 and the feeding point 30 connected to the antenna radiator 10, or by arranging the lumped element 20 between the antenna radiator 10 and the feeding point 40 connected to the antenna radiator 10, the performance of the antenna is adjusted by using the difference in the degree of influence of the lumped element 20 on the performance of the antenna in different operating frequency bands, so that the degree of influence of the performance of the antenna radiators 10 on each other is reduced, and the performance of each antenna is ensured.
