Detailed Description
To better illustrate the present invention, a preferred embodiment is described in detail with reference to the accompanying drawings, in which:
as shown in fig. 1, the metal frame mobile phone antenna provided in this embodiment is disposed on one side of the slot of the metal frame 400 of the mobile phone, the metal frame on the side is provided with a first slot 401 and a second slot 402, and the antenna includes the diversity antenna portion 200 and the WIFI antenna portion 300 disposed on the PCB 100. Wherein the highest position of the antenna main body part is 4mm away from the upper surface of the PCB board 100. I.e. the PCB is seen from the side, the antenna body portion is larger than 4mm of the thickness of the PCB.
As shown in fig. 2 and 3, the diversity antenna portion 200 includes a diversity antenna ground branch 202 and a diversity antenna feed portion 201 connected to the PCB board 100, and the diversity antenna ground branch 202 and the diversity antenna feed portion 201 connected to the PCB board 100 have a diversity ground point and a diversity feed point, respectively. The diversity antenna ground branch 202 and the diversity antenna feed portion 201 are connected to a diversity antenna feed first branch 205, the diversity antenna feed first branch 205 is a metal frame located on one side of the first slot 401 close to the second slot 402, i.e. on the right side of the first slot 401 in fig. 2, and the metal frame on the other side (left side in fig. 1) of the first slot 401 is a diversity antenna parasitic first branch (204); the WIFI antenna portion 300 includes a WIFI antenna ground branch 302 and a WIFI antenna feed portion 301 connected to the PCB board 100, the WIFI antenna feed portion 301 is further connected to a WIFI antenna feed first branch 303 and a WIFI antenna feed second branch 304, the WIFI antenna feed first branch 303 is not in contact with the metal frame, and the WIFI antenna feed second branch 304 is a metal frame located on one side of the second slot 402 away from the first slot 401, that is, located on the right side of the second slot in fig. 2.
The diversity antenna part 200 further comprises a diversity antenna tuning branch 203, one end of the diversity antenna tuning branch 203 is connected to the diversity antenna grounding branch 202, the other end is connected to the PCB board 100, and a radio frequency tuner is connected in series between the diversity antenna grounding branch 202 and the PCB board 100, and when the antenna is applied, the capacitance value of the radio frequency tuner can be adjusted according to the low frequency length, so as to change the frequency value of the low frequency signal.
The position of the upper frame point at which the diversity antenna feeding portion 201 in this embodiment is connected to the diversity antenna feeding first branch 205 is not fixed, and the position of the upper frame point is adjustable along the metal frame direction, specifically, along the left-right direction of the metal frame in fig. 2. In addition, the position of the diversity grounding point of the diversity antenna grounding branch 202 in this embodiment is also not fixed, and the position of the diversity grounding point can be variably adjusted for a desired resonant frequency position. When the low-frequency resonance frequency is lower, the grounding point moves to the left side for adjustment, and conversely, moves to the right side for adjustment. The position of the grounding point of the parasitic first branch 204 of the diversity antenna is fixed, but the grounding position can be adjusted according to the length of the GPS frequency band so as to achieve the purpose of adjusting the length of the parasitic first branch of the diversity antenna, and the length can be determined according to the inverse conversion relation between the wavelength of the GPS frequency band and the resonant frequency.
The distance between the position of the upper frame point connected with the WIFI antenna feed part 301 and the WIFI antenna feed second branch 304 and the slit of the metal frame is 0-8 mm, preferably 5mm, and the distance is relatively close to the slit.
The grounding point of the WIFI antenna grounding branch 302 is not fixed, and is 0-8 mm, preferably 6mm, away from the feeding point of the WIFI antenna feeding portion 301.
The length of the WIFI antenna feed first branch 303 is the same as the resonance length at which WIFI2.4GHz is located, or the same as the resonance length at which WIFI5GHz is located. The specific length calculation can be obtained according to the inverse conversion relation of the wavelength and the resonant frequency.
When the antenna works, a low-frequency resonance is coupled out by the diversity antenna feeding first branch 205 and the diversity antenna parasitic first branch 204, and the length of the diversity antenna feeding first branch 205 determines the position of the low-frequency resonance; while the low frequency resonance position can be adjusted by changing the capacitance value of the radio frequency Tuner (RF-Tuner) in series with the diversity antenna tuning branch 203.
The diversity antenna parasitic first branch 204 creates a first high frequency resonance whose length determines the location of the first high frequency resonance. The diversity antenna feed first branch 205 is slot coupled to the metal frame to generate a second high frequency resonance in cooperation with its own intrinsic resonance. The location of the upper box point of the diversity antenna feed portion 201 affects the location of the second high frequency resonance while the coupling between the diversity antenna parasitic first branch 204 and the diversity antenna feed first branch 205 enhances the radiation performance of the high frequency first resonance.
The WIFI antenna feed first branch 303 couples with the WIFI antenna feed second branch 304 to generate a WIFI2.4ghz resonance, and the coupling of the two helps to enhance the radiation performance of the WIFI2.4 ghz. The length of the WIFI antenna feeding first branch 303 determines the position of the resonance of wifi2.4 ghz.
The position of the grounding point of the WIFI antenna grounding branch 302 determines the resonant position of WIFI5GHz, and the position of the grounding point of the WIFI antenna close to the diversity antenna feeding portion 201 greatly improves the isolation between the diversity antenna and the WIFI antenna.
As shown in fig. 4, the actual measurement result of the diversity antenna S11 provided by this embodiment shows that the antenna provided by this embodiment completely covers all frequency bands of diversity reception.
As shown in fig. 5, the actual measurement result of the WIFI antenna S11 provided by this embodiment shows that the antenna provided by this embodiment completely covers all frequency bands of WIFI2.4G and 5G.
As shown in fig. 6, the result of S21 (actual measurement of mockup) of the isolation between the diversity antenna and the WIFI antenna provided in this embodiment shows that the antenna provided in this embodiment well solves many adverse effects (such as GPS receiving sensitivity, WIFI radiation power, receiving sensitivity, etc.) on communication caused by poor isolation effect of the small top antenna of the conventional mobile terminal.
As shown in fig. 7, in the actual measurement efficiency of the diversity antenna Mockup provided by this embodiment, the low-frequency (790MHz-960MHz) efficiency is greater than or equal to 28%, the high-frequency (1710MHz-2700MHz) efficiency is greater than or equal to 37%, and the GPS (1525MHz-1625NHz) efficiency is greater than or equal to 58%.
As shown in fig. 8, the actually measured efficiency of the WIFI antenna Mockup provided by this embodiment is greater than or equal to 45% of WIFI2.4G (2380MHz-2500MHz) efficiency, and greater than or equal to 55% of WIFI5G (5100MHz-5900MHz) efficiency.
In sum, the isolation of the diversity antenna and the WIFI antenna is higher than 10dB in the full frequency band. This is a performance that is difficult to achieve with other metal frame handset antennas. Therefore, the metal frame mobile phone antenna (diversity antenna and WIFI antenna) 0 provided by the invention can greatly improve the isolation between the small metal frame mobile phone antennas, so that the performance which cannot be achieved by other schemes can be achieved.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to make modifications or substitutions within the technical scope of the present invention.
