Description

Technical Field

[0001] The present invention relates to the field of antennas, and in particular to a frequency-dividing antenna that does not interfere with each other. Background Art

[0002] Antenna configuration is a crucial component in 5G NSA (non-standalone) terminal design to support concurrent communications across multiple frequency bands. To address this challenge, advanced tunable antenna technology is employed to dynamically expand the antenna's operating frequency range to cover a wide range of 5G and compatible frequency bands. However, this technology faces a significant implementation challenge: optimizing tuning for low-frequency bands can inadvertently impact performance in mid-band and even high-frequency bands, leading to fluctuations in overall communication efficiency and stability.

[0003] Furthermore, the antenna systems integrated within 5G terminals generate heat while efficiently transmitting signals. This heat is not only generated by electromagnetic radiation conversion losses within the antenna itself, but also by the heat dissipation of other densely integrated electronic components within the terminal (such as processors and RF front-end modules). Especially in extreme environmental conditions, such as high temperature, high humidity, or confined spaces, heat accumulation can significantly affect the antenna's electrical characteristics, including gain attenuation, pattern distortion, and polarization changes, thereby reducing communication quality and coverage.

[0004] Given the pursuit of miniaturization in modern mobile devices, the space left for antennas and their heat dissipation solutions is extremely limited. Therefore, how to effectively manage the heat of the antenna system within this limited space has become a technical challenge that needs to be solved urgently.

[0031] Compared with the prior art, the present invention provides a frequency-dividing antenna that does not interfere with each other, which has the following beneficial effects:

[0032] 1. This non-interfering frequency-dividing antenna is composed of a low-frequency antenna vibrator and a high-frequency antenna vibrator. Combined with a frequency-dividing module, the antenna can effectively operate in a wide frequency band and reduce the mutual influence between frequencies. In addition, the microstrip antenna adopts a laminated structure design, which effectively reduces the antenna area and improves space utilization.

[0033] 2. The frequency-dividing antenna, which does not interfere with each other, can effectively dissipate heat for the antenna through the heat dissipation component and the flow regulation component. It can also automatically control the coolant flow according to the surrounding temperature, dynamically adjust the flow according to the actual heat generation, increase the flow when the heat is high to enhance the heat dissipation effect, avoid overheating of the equipment, and ensure that the equipment operates within a safe temperature range. Reducing the flow when the heat is low can reduce the power consumption of the pump and save energy. For example, when the 5G terminal is in a low-load operating state, the antenna generates less heat. At this time, reducing the coolant flow can reduce energy consumption, and the micro water pump combined with the first cooling pipe realizes coolant circulation heat dissipation, which can not only fully contact various parts of the heat-generating components, making the heat distribution more even, but also has relatively low noise.

The flow regulating assembly includes a heat-conducting tube 20 fixedly provided on a fixing frame 21. One end of the heat-conducting tube 20 extends to the outside of the support body 1.

[0064] When in use, the signal received by the antenna first enters the frequency division module through the antenna feed point 14. This frequency division module is composed of two reflective filters, one for high-frequency signals and the other for low-frequency signals. After the signal is divided, it enters the corresponding sub-antenna through the low-pass filter 13 and the high-pass filter 12 respectively, that is, the low-frequency antenna vibrator 4 and the high-frequency antenna vibrator 5. The low-frequency antenna vibrator 4 (PIFA antenna) receives the low-frequency signal processed by the low-pass filter 13, and achieves resonance by adjusting its physical structure or the loaded tuning network. The high-frequency antenna vibrator 5 (loop antenna) receives the high-frequency signal processed by the high-pass filter 12, and also achieves resonance by adjusting its structure or tuning network. The ground of each sub-antenna is passed through The control switch is connected to the ground. The control switch consists of a high-frequency control switch 11 and a low-frequency control switch 15. These switches are AW17445 signals, which are controlled by GPIO and can be turned on or off as needed to adjust the performance of the antenna or achieve frequency control. The low-pass filter network (L1, L2, L3, C1, C2) is used to filter out high-frequency signals to ensure that the low-frequency signals are transmitted cleanly to the low-frequency antenna element 4. The high-pass filter network (L4, C3, C4, C5, C6) is used to filter out low-frequency signals to ensure that the high-frequency signals can be efficiently transmitted to the high-frequency antenna element 5. The component values ​​of the inductor L and the capacitor C in these filter networks are carefully designed to achieve the required frequency response and impedance matching;

[0065] In addition, when the antenna is used in the terminal, a temperature sensor can be set around it, and the micro water pump 17 can be started and stopped actively or automatically. When the temperature reaches the set value, the micro water pump 17 starts, and the micro water pump 17 extracts the coolant stored in the storage box 6, enters the liquid inlet tee 25 through the second connecting pipe 24, and then enters one of the first cooling pipes 16 from one end of the liquid inlet tee 25. The coolant circulates in the first cooling pipe 16, and then dissipates heat at the low-frequency antenna vibrator 4, the high-frequency antenna vibrator 5, the first feeding column 9, the second feeding column 10, the high-frequency control switch 11, the high-pass filter 12, the low-pass filter 13, and the low-frequency control switch 15. After that, the coolant enters the first connecting pipe 23 through one end of the liquid outlet tee 22, and enters the second cooling pipe 37 through the first connecting pipe 23. It is cooled under the action of the second cooling pipe 37 and the heat sink 7, and then returns to the storage box 6 again, thus circulating;

[0066] It should be noted that initially, the first regulating piece 30 and the second connecting pipe 24 are not completely blocked, while the second regulating piece 32 completely blocks both the outlet tee 22 and one end of the inlet tee 25. Therefore, initially, the coolant can enter the inlet tee 25 through the second connecting pipe 24, but can only enter one of the first cooling pipes 16 from one end of the inlet tee 25. Then, the coolant can only enter one end of the outlet tee 22 from the first cooling pipe 16, and then enter the first connecting pipe 23.

[0067] When the temperature around the antenna is high, the driving source 36 is a spring structure that can expand and contract with heat, and the spring structure is made of nickel-titanium alloy. The driving source 36 stretches, and then drives the driving piece 26 to move through the guide rod 35, and the driving piece 26 drives the first guide groove 38 and the second guide groove 39 to move synchronously. Initially, the roller 40 is located in the second guide groove 39 away from the end of the first guide groove 38, so that when the driving piece 26 is displaced, it will drive the roller 40 and the first adjustment rod 31 to move upward as a whole, and then the first adjustment rod 31 drives the first adjustment piece 30 to move upward, and the flow in the second connecting pipe 24 can increase, thereby increasing the heat dissipation effect. When the temperature continues to rise, the limit block 43 contacts the end of the inner side of the traction groove 42 close to the guide rod 35, so that the pulling rod 34 is driven by the driving piece 26 to move, and the pulling rod 34 drives the connecting plate 29 to move. The connecting plate 29 drives the two second adjustment pieces 32 to move through the second adjustment rod 33, thereby discharging three liquids. When the temperature drops to a certain level, the driving source 36 will gradually retract, and the driving piece 26 will be retracted. When the temperature drops to a certain level, the inner wall of the end of the traction groove 42 away from the guide rod 35 will drive the pulling rod 34 to move through the limit block 43, and then the pulling rod 34 drives the connecting plate 29 to move and retract, and one end of the liquid outlet tee 22 and the liquid inlet tee 25 is blocked again. When the temperature continues to drop, the roller 40 enters the second guide groove 39, the first adjusting piece 30 gradually moves downward, and the flow rate of the second connecting pipe 24 is reduced to adapt to the low temperature.

[0068] The expansion temperature (phase transition temperature) of the above nickel-titanium alloys varies depending on their composition and grade. The expansion temperature range of common nickel-titanium alloys is roughly as follows:

[0069] TiNi-01 grade: phase transition temperature is 20℃-40℃;

[0070] TiNi-02 grade: phase transition temperature is 45℃-90℃;

[0071] TiNi-ss grade: phase transition temperature is 5℃-15℃;

[0072] TiNi-yy grade: phase transition temperature is about 33℃±3℃;

[0073] When the temperature of nickel-titanium alloy changes, it transforms between the austenite phase (a high-temperature phase with a relatively stable shape) and the martensite phase (a low-temperature phase with ductility, reproducibility, and ease of deformation), resulting in a change in shape, known as telescoping. The temperature range of the drive source 36 of the present application can be selected from any of the above, depending on the specific use environment and requirements.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
