Description
- Embodiments of this application relate to the field of communications technologies, and in particular, to an antenna.
- Currently, printed antennas commonly used in Wi-Fi products mainly include a monopole antenna, a printed inverted F antenna, a loop antenna, and the like. A main feature of such type of printed antennas is that a signal of each printed antenna is radiated in a single direction, offering a limited coverage angle.
- To ensure better coverage performance of a Wi-Fi product, a combination of a plurality of printed antennas needs to be disposed on a circuit board of the Wi-Fi product, so that the Wi-Fi product has a plurality of signal radiation directions, to implement wider coverage.
- However, increasing a quantity of printed antennas on the circuit board of the Wi-Fi product not only increases manufacturing costs, but also occupies more space on the circuit board of the Wi-Fi product.
- Embodiments of this application provide an antenna, so that the antenna can send signals in two directions, to increase a radiation range of the antenna.
- The embodiments of this application are implemented as follows:
- According to a first aspect, an embodiment of this application provides an antenna, where the antenna is disposed on an insulation medium of a circuit board, and the antenna includes a loop radiator, a signal feed-in part, a first conductive ground structure, and a second conductive ground structure, where
a first end of the loop radiator is connected to the first conductive ground structure, a second end of the loop radiator is connected to the signal feed-in part, and the loop radiator independently generates a first radiation signal based on a function of a current;
the loop radiator and the second conductive ground structure form a groove, the loop radiator and the second conductive ground structure jointly generate a second radiation signal in an opening direction of the groove based on a function of a current, and a radiation direction of the first radiation signal is different from a radiation direction of the second radiation signal; and
all of the signal feed-in part, the first conductive ground structure, and the second conductive ground structure are connected to a radio frequency circuit of the circuit board. - In the first aspect, a radio frequency signal on the radio frequency circuit of the circuit board passes through the signal feed-in part, the first conductive ground structure, and the second conductive ground structure to feed the loop radiator, and flows to two ends of the loop radiator respectively through the signal feed-in part and the first conductive ground structure. The loop radiator independently generates the first radiation signal based on the function of the current. The loop radiator and the second conductive ground structure further jointly generate the second radiation signal in the opening direction of the groove based on the function of the current. The radiation direction of the first radiation signal is different from the radiation direction of the second radiation signal. Therefore, the antenna provided in this embodiment of this application can send signals in two directions, thereby increasing a radiation range of the antenna. Because the antenna provided in this embodiment of this application has a wider radiation range, a quantity of antennas on a circuit board of a Wi-Fi product can be decreased, thereby not only reducing manufacturing costs, but also reducing occupied space on the circuit board of the Wi-Fi product.
- In a possible implementation, an opening of the groove is outward, and an opening width of the groove gradually increases from the inside to the outside.
- Because the opening width of the groove gradually increases from the inside to the outside, enabling wave impedance of the groove in air to gradually increase from the inside to the outside, reflection of the second radiation signal on an inside-to-outside transmission path in the groove is lower, thereby ensuring a better transmission effect of the second radiation signal in the air.
- In a possible implementation, an opening width of a tail end of the groove is a quarter wavelength corresponding to a center frequency of the antenna.
- In a possible implementation, the loop radiator includes a first radiator, a second radiator, and a third radiator, where
a first end of the first radiator is connected to the first conductive ground structure, a second end of the first radiator is connected to a first end of the second radiator, a second end of the second radiator is connected to a first end of the third radiator, and a second end of the third radiator is connected to the signal feed-in part;
the second radiator independently generates the first radiation signal based on the function of the current, and the radiation direction of the first radiation signal is perpendicular to the second radiator; and
the third radiator and the second conductive ground structure jointly form the groove whose opening is outward, and the third radiator and the second conductive ground structure jointly generate the second radiation signal in the opening direction of the groove based on the function of the current. - A current in the radio frequency circuit of the circuit board flows to the signal feed-in part, the first conductive ground structure, and the second conductive ground structure, a current flows to the second radiator through the first conductive ground structure and the first radiator, and a current flows to the third radiator through the signal feed-in part. The second radiator independently generates the first radiation signal based on the function of the current, the third radiator and the second conductive ground structure further jointly generate the second radiation signal in the opening direction of the groove based on the function of the current, and the radiation direction of the first radiation signal is different from the radiation direction of the second radiation signal. Therefore, the antenna provided in this embodiment of this application can send signals in two directions, thereby increasing a radiation range of the antenna.
- In a possible implementation, the antenna further includes at least one horizontal radiator, where
the at least one horizontal radiator is disposed on a side surface of the second radiator, the at least one horizontal radiator and the second radiator jointly generate a third radiation signal based on a function of a current, a radiation direction of the third radiation signal is the same as the radiation direction of the first radiation signal, and radiant intensity of the third radiation signal is greater than radiant intensity of the first radiation signal. - The current in the radio frequency circuit of the circuit board flows to the second radiator through the first conductive ground structure and the first radiator, and the second radiator independently generates the first radiation signal based on the function of the current. Under the function of the first radiation signal, the at least one horizontal radiator generates a current having a direction the same as a direction of the current in the second radiator. Therefore, under the joint function of the current in the at least one horizontal radiator and the current in the second radiator, the at least one horizontal radiator and the second radiator jointly generate the third radiation signal. Because the third radiation signal is jointly generated by the at least one horizontal radiator and the second radiator, the radiant intensity of the third radiation signal is greater than the radiant intensity of the first radiation signal. Therefore, the at least one horizontal radiator can improve radiant intensity of the antenna.
- In a possible implementation, a length range of the at least one horizontal radiator is the quarter wavelength to a half wavelength corresponding to the center frequency of the antenna.
- In a possible implementation, a first gap is formed between the signal feed-in part and the first conductive ground structure, and an opening formed between the first radiator and the third radiator communicates with the first gap; and
a second gap is formed between the signal feed-in part and the second conductive ground structure, and the groove formed between the third radiator and the second conductive ground structure communicates with the second gap. - A width of the signal feed-in part, a width of the first gap, and a width of the second gap may be adjusted based on an impedance calculation principle of a coplanar waveguide, to ensure that impedance of the antenna matches impedance of the radio frequency circuit of the circuit board. In this way, a signal reflection loss in a feed-in process can be avoided, to ensure that efficiency of feed-in the antenna by the radio frequency circuit of the circuit board is the highest.
- In a possible implementation, the third radiator is of a straight line structure or a curved structure.
- In a possible implementation, all of the loop radiator, the signal feed-in part, the first conductive ground structure, and the second conductive ground structure are printed on the insulation medium of the circuit board.
- In a possible implementation, all of the loop radiator, the signal feed-in part, the first conductive ground structure, and the second conductive ground structure are fixedly connected to the insulation medium of the circuit board, and all of the loop radiator, the signal feed-in part, the first conductive ground structure, and the second conductive ground structure are made of metal materials.

- As shown in
FIG. 1, FIG. 1 is a schematic diagram of anantenna 10 according to an embodiment of this application. Theantenna 10 shown inFIG. 1 is disposed on aninsulation medium 21 of a circuit board. Theantenna 10 includes aloop radiator 1, a signal feed-inpart 2, a firstconductive ground structure 3, and a secondconductive ground structure 4. - A first end of the
loop radiator 1 is connected to the firstconductive ground structure 3, a second end of theloop radiator 1 is connected to the signal feed-inpart 2, and theloop radiator 1 independently generates a first radiation signal based on a function of a current. Theloop radiator 1 and the secondconductive ground structure 4 form a groove, theloop radiator 1 and the secondconductive ground structure 4 jointly generate a second radiation signal in an opening direction of the groove based on a function of a current, and a radiation direction of the first radiation signal is different from a radiation direction of the second radiation signal. All of the signal feed-inpart 2, the firstconductive ground structure 3, and the secondconductive ground structure 4 are connected to aradio frequency circuit 22 of the circuit board. - In
FIG. 1 , the radiation direction of the first radiation signal is perpendicular to a horizontal plane and is upward, and the radiation direction of the second radiation signal is horizontally rightward. Therefore, it can be learned from the embodiment ofFIG. 1 that the radiation direction of the first radiation signal is different from the radiation direction of the second radiation signal, and the radiation direction of the first radiation signal is perpendicular to the radiation direction of the second radiation signal. Certainly, a shape of theantenna 10 may be fine-adjusted, to adjust the radiation direction of the first radiation signal and the radiation direction of the second radiation signal. - In the embodiment shown in
FIG. 1 , a radio frequency signal on theradio frequency circuit 22 of the circuit board passes through the signal feed-inpart 2, the firstconductive ground structure 3, and the secondconductive ground structure 4 to feed theloop radiator 1, and a current flows to two ends of theloop radiator 1 respectively through the signal feed-inpart 2 and the firstconductive ground structure 3. Theloop radiator 1 independently generates the first radiation signal based on the function of the current. Theloop radiator 1 and the secondconductive ground structure 4 further jointly generate the second radiation signal in the opening direction of the groove based on the function of the current. The radiation direction of the first radiation signal is different from the radiation direction of the second radiation signal. Therefore, theantenna 10 provided in this embodiment of this application can send signals in two directions, thereby increasing a radiation range of theantenna 10. Because theantenna 10 provided in this embodiment of this application has a wider radiation range, a quantity ofantennas 10 on a circuit board of a Wi-Fi product can be decreased, thereby not only reducing manufacturing costs, but also reducing occupied space on the circuit board of the Wi-Fi product. - As shown in
FIG. 1 , in an optional technical solution, an opening of the groove is outward, and an opening width of the groove gradually increases from the inside to the outside. - In the technical solution provided in this embodiment of this application, because the opening width of the groove gradually increases from the inside to the outside, enabling wave impedance of the groove in air to gradually increase from the inside to the outside, reflection of the second radiation signal on an inside-to-outside transmission path in the groove is lower, thereby ensuring a better transmission effect of the second radiation signal in the air.
- As shown in
FIG. 1 , in an optional technical solution, an opening width of a tail end of the groove is a quarter wavelength corresponding to a center frequency of theantenna 10. - In the technical solution provided in this embodiment of this application, a wavelength may be calculated according to a formula r=c/f, where r represents a wavelength in a unit of meter, c represents a speed of light in a unit of meter/second, and f is the center frequency of the
antenna 10 in a unit of Hz. - As shown in

Certainly, theloop radiator 1, the signal feed-inpart 2, the firstconductive ground structure 3, and the secondconductive ground structure 4 may be directly printed on theinsulation medium 21 of the circuit board of the Wi-Fi product. In addition, theloop radiator 1, the signal feed-inpart 2, the firstconductive ground structure 3, and the secondconductive ground structure 4 may be alternatively printed on aninsulation medium 21 of a micro circuit board having a relatively small area, and then the micro circuit board is inserted into or welded onto the circuit board of the Wi-Fi product for use. Therefore, requirements of different Wi-Fi products are met by using different printing manners. - As shown in

For example, all of the
loop radiator 1, the signal feed-inpart 2, the firstconductive ground structure 3, and the secondconductive ground structure 4 may be adhered to theinsulation medium 21 of the circuit board. - After all of the
loop radiator 1, the signal feed-inpart 2, the firstconductive ground structure 3, and the secondconductive ground structure 4 are fixedly connected to theinsulation medium 21 of the micro circuit board, the micro circuit board may be inserted into or welded onto the circuit board of the Wi-Fi product for use. - As shown in
FIG. 2, FIG. 2 is a schematic diagram of anotherantenna 10 according to an embodiment of this application. Compared with the embodiment shown inFIG. 1 , a specific structure of theloop radiator 1 is described in more details in the embodiment shown inFIG. 2 . Theloop radiator 1 includes afirst radiator 11, asecond radiator 12, and athird radiator 13. - A first end of the

Therefore, theantenna 10 provided in this embodiment of this application can send signals in two directions, thereby increasing a radiation range of theantenna 10. - As shown in
FIG. 3, FIG. 3 is a schematic diagram of still anotherantenna 10 according to an embodiment of this application. Based on the embodiment shown inFIG. 2 , an extra component is added in the embodiment shown inFIG. 3 . Theantenna 10 may further include at least onehorizontal radiator 5. - The at least one
horizontal radiator 5 is disposed on a side surface of thesecond radiator 12, the at least onehorizontal radiator 5 and thesecond radiator 12 jointly generate a third radiation signal based on a function of a current, a radiation direction of the third radiation signal is the same as the radiation direction of the first radiation signal, and radiant intensity of the third radiation signal is greater than radiant intensity of the first radiation signal. - In the embodiment shown in
FIG. 3 , the current in theradio frequency circuit 22 of the circuit board flows to thesecond radiator 12 through the firstconductive ground structure 3 and thefirst radiator 11, and thesecond radiator 12 independently generates the first radiation signal based on the function of the current. Under the function of the first radiation signal, the at least onehorizontal radiator 5 generates a current having a direction the same as a direction of the current in thesecond radiator 12. Therefore, under the joint function of the current in the at least onehorizontal radiator 5 and the current in thesecond radiator 12, the at least onehorizontal radiator 5 and thesecond radiator 12 jointly generate the third radiation signal. Because the third radiation signal is jointly generated by the at least onehorizontal radiator 5 and thesecond radiator 12, the radiant intensity of the third radiation signal is greater than the radiant intensity of the first radiation signal. Therefore, the at least onehorizontal radiator 5 can improve radiant intensity of theantenna 10. - As shown in

FIG. 3 andFIG. 4 , in an optional technical solution, a length range of the at least onehorizontal radiator 5 is the quarter wavelength to a half wavelength corresponding to the center frequency of theantenna 10. A wavelength may be calculated according to the formula r=c/f in the foregoing embodiment, where r represents a wavelength in a unit of meter, c represents a speed of light in a unit of meter/second, and f is the center frequency of theantenna 10 in a unit of Hz. - As shown in
