[0033] In the mobile Internet era, the functions of terminal devices such as smart phones are increasingly rich, the performance is increasingly superior, and the degree of dependence and use frequency of users on terminal devices are also greatly improved. While the mobile Internet technology brings the above conveniences to terminal devices, it also puts forward certain requirements for the hardware used for communication of terminal devices, such as antennas.

[0034] In the related art, the antenna is often formed by reusing the middle frame of the terminal device, but the size of the middle frame of the terminal device is limited, and the number of antennas configured by the terminal device is increasing, which makes the radiation ability of the antennas formed by the limited middle frame poor, and further leads to poor communication effect of the terminal device.

[0035] Therefore, in a first aspect, at least one embodiment of the disclosure provides an antenna combination which can be arranged in a terminal device to enhance the radiation ability of a plurality of antennas formed by the limited size middle frame of the terminal device.

[0036] Please refer to the accompanying drawings Figure 1 to the accompanying drawings Figure 4 which exemplarily show the preferred structure of the antenna combination. It can be understood that the accompanying drawings Figure 1 to the accompanying drawings Figure 4 shown are not a limitation on the structure of the antenna combination provided by the disclosure.

The radiation frequency of the first antenna is adapted to its function, for example, the radiation frequency of a 2.4G antenna for radiating Bluetooth signals and wireless network signals is 2.4G. Preferably, the length of the first antenna is related to the radiation frequency of the first antenna, for example, the length of the first antenna and the radiation frequency of the first antenna satisfy the following relationship:

[0046] It should be understood that if the length of the middle frame that can be allocated to the second antenna is greater than or equal to the length determined in the preferred mode, the length of the second antenna is configured as the length; if the length of the middle frame that can be allocated to the second antenna is less than the length determined in the preferred mode, the length of the second antenna is configured as the length of the middle frame that can be allocated to the second antenna.

[0047] The parasitic branch between the first antenna and the second antenna is a suspended branch on the middle frame that is not used as an antenna. The parasitic branch is not directly grounded, for example, through inductance, capacitance and the like.

[0048] Optionally, the preset range in which the length of the parasitic branch is located is related to the working wavelength of the first antenna and the working wavelength of the second antenna, wherein the working wavelength of the first antenna is related to the radiation frequency of the first antenna, and the working wavelength of the second antenna is related to the radiation frequency of the second antenna.

[0049] For example, the working wavelength of the first antenna and the radiation frequency of the first antenna satisfy the following relationship:

[0050]

[0051] In the above formula, f1 is the radiation frequency of the first antenna, λ ∈1 is the working wavelength of the first antenna, ε r is the dielectric constant of the plastic of the terminal device, and c is the speed of light.

[0053]

[0054] In the above formula, f2 is the radiation frequency of the second antenna, λ ∈2 is the working wavelength of the second antenna, ε r is the dielectric constant of the plastic of the terminal device, and c is the speed of light.

[0056] For example, the preset range is a left-closed right-open interval from 1 / 8 times the working wavelength of the second antenna to 3 / 4 times the working wavelength of the first antenna. That is:

[0057]

[0058]

[0059] In the above formula, L3 is the length of the parasitic branch, λ ∈1(2) is the operating wavelength of the first antenna (i.e. the operating wavelength of the second antenna), f1 is the radiation frequency of the first antenna, ε r is the plastic dielectric constant of the entire terminal device, and c is the speed of light.

[0060] Optionally, when the radiation frequency of the first antenna is lower than the radiation frequency of the second antenna, the lower limit of the preset range is related to the radiation frequency of the second antenna, and the upper limit of the preset range is related to the radiation frequency of the first antenna.

[0061] For example, the preset range is the left-closed and right-open interval from 1 / 8 times the working wavelength of the second antenna to 3 / 4 times the working wavelength of the first antenna. That is:

[0062]

[0063]

[0064]

[0066] It should be understood that when When , the aperture enhancement effect of the second antenna is the best; when When the third harmonic frequency of the second antenna falls within the band of the first antenna, the third harmonic frequency of the first antenna falls within the band of the second antenna. Then there will be pits in the bands of both the first and second antennas, and the radiation efficiency will be very poor.

[0067] Preferably, when the radiation frequency of the first antenna is lower than the radiation frequency of the second antenna, the lower limit of the preset range is related to the radiation frequency of the second antenna, and the upper limit of the preset range is related to the radiation frequency of the second antenna.

[0068] For example, the preset range is a left-closed and right-open interval between 1 / 8 times the working wavelength of the second antenna and 3 / 4 times the working wavelength of the second antenna.

[0069]

[0070]

[0071]

[0072] In the above formula, L3 is the length of the parasitic branch, λ ∈1 is the operating wavelength of the first antenna, λ ∈2 is the operating wavelength of the second antenna, f1 is the radiation frequency of the first antenna, f2 is the radiation frequency of the first antenna, ε r is the plastic dielectric constant of the terminal device, and c is the speed of light.

[0073] It should be understood that when , the aperture enhancement effect on the second antenna is the best; when , the third harmonic of the second antenna will fall within the band of the first antenna, and the third harmonic of the first antenna will fall within the band of the second antenna, so that there are pits in the bands of the first antenna and the second antenna, and the radiation efficiency is poor; when , the third harmonic of the second antenna will fall within the band of the first antenna, forming a pit and affecting the radiation efficiency of the first antenna.
