First embodiment

First, referring to fig. 1 and 2, a first embodiment of the present invention provides an electronic device U, which has a function of receiving and transmitting Radio Frequency (RF) signals. For example, the electronic device U may be a Smart Phone (Smart Phone), a Tablet Computer (Tablet Computer), or a notebook Computer (Notebook Computer), but the invention is not limited thereto. In addition, the electronic device U can generate a first operating frequency band and a second operating frequency band, and the first operating frequency band is higher than the second operating frequency band. Further, the center frequency of the first operating frequency band is higher than the center frequency of the second operating frequency band. In addition, for example, the electronic device U can generate an operating frequency band (a first operating frequency band) with a frequency range between 1710MHz and 2690MHz and an operating frequency band (a second operating frequency band) with a frequency range between 698MHz and 960MHz, but the invention is not limited thereto.

In view of the foregoing, the present invention will take the electronic device U as a notebook computer as an example, the electronic device U includes a first radiating element 1, a second radiating element 2, a grounding element 3 and a feeding element 4, and the first radiating element 1, the second radiating element 2, the grounding element 3 and the feeding element 4 can form an antenna module a disposed in the electronic device U and used for receiving and transmitting radio frequency signals. In addition, the electronic device U may further include a first substrate S1, a second substrate S2, a first housing H1, and a second housing H2, for example. The first housing H1 may be a C piece (inside of the base) of the notebook computer, and the second housing H2 may be a D piece (outside of the base) of the notebook computer, that is, fig. 2 is a schematic top view of the first housing H1 flipped left, but the invention is not limited thereto. In addition, in other embodiments, when the electronic device U is a smart phone or a tablet computer, the first housing H1 and the second housing H2 may be two corresponding outer housings of the smart phone or the tablet computer, respectively.

Next, referring to fig. 1 and 2, and referring to fig. 3 and 4, in the first embodiment, the first radiation member 1 is disposed adjacent to the first housing H1, and the second radiation member 2 is disposed adjacent to the second housing H2, that is, the first radiation member 1 is disposed adjacent to the first housing H1 than the second radiation member 2, and the second radiation member 2 is disposed adjacent to the second housing H2 than the first radiation member 1. Further, for example, the first substrate S1 is disposed on the first housing H1, the second substrate S2 is disposed on the second housing H2, and the first radiation member 1 is disposed on the first substrate S1, and the second radiation member 2 is disposed on the second substrate S2. However, it should be noted that, although the first embodiment of the present invention uses the structure that the first radiating element 1 and the second radiating element 2 are respectively disposed on the first substrate S1 and the second substrate S2, so that the first radiating element 1 and the second radiating element 2 are respectively adjacent to the first housing H1 and the second housing H2 as an example, in other embodiments, the first radiating element 1 and the second radiating element 2 may be respectively disposed on two opposite surfaces of the same substrate S (refer to fig. 7). The present invention is not limited in the manner that the first radiator 1 and the second radiator 2 are disposed between the first housing H1 and the second housing H2. It should be noted that, in one embodiment, the first radiator 1 is mainly used for generating an operating frequency band with a frequency range between 1710MHz and 2690MHz, and the second radiator 2 is mainly used for generating an operating frequency band with a frequency range between 698MHz and 960MHz, but the invention is not limited thereto.

For example, the material of the first housing H1 may be metal, the material of the second housing H2 may be metal, and the grounding element 3 may be electrically connected to the first housing H1 when the material of the first housing H1 is metal. However, it should be noted that the second housing H2 has at least one non-metallic region H20 corresponding to a contour of the second radiation member 2. Further, in order to avoid that the second housing H2 made of metal affects the radiation efficiency of the second radiation member 2, the perpendicular projection of the second radiation member 2 on the second housing H2 at least partially overlaps the non-metal area H20. Preferably, in one embodiment, the area of the perpendicular projection of the second radiation member 2 on the second housing H2 is smaller than the area of the non-metal area H20, and the perpendicular projection of the second radiation member 2 on the second housing H2 is completely overlapped on the non-metal area H20. In addition, for example, as shown in fig. 3, the non-metal area H20 may be a slot of the second housing H2, however, in other embodiments, a non-metal member (please refer to fig. 7) such as plastic may be filled in the slot of the second housing H2, however, the present invention is not limited to the forming manner of the non-metal area H20 of the second housing H2.

In the above description, the material of the first housing H1 and the second housing H2 is used as metal, the vertical projection of the first radiation member 1 on the first housing H1 is at least partially overlapped with or completely overlapped with the metal area (not numbered in the figure) on the first housing H1, the vertical projection of the second radiation member 2 on the first housing H1 is at least partially overlapped with or completely overlapped with the metal area (not numbered in the figure) on the first housing H1, and the vertical projection of the second radiation member 2 on the second housing H2 is at least partially overlapped with the nonmetal area H20 on the second housing H2. However, in other embodiments, the material of the second housing H2 may be non-metal. That is, the present invention can be applied to an electronic device U with at least one of the first housing H1 and the second housing H2 being made of metal, wherein the first radiating element 1 for generating a higher operating frequency band is more adjacent to the first housing H1 made of metal than the second radiating element 2 for generating a lower operating frequency band, and the second radiating element 2 for generating a lower operating frequency band is more adjacent to the second housing H2 made of metal or nonmetal than the first radiating element 1 for generating a higher operating frequency band, so that the overall radiation efficiency is improved. In addition, it should be noted that, no matter the material of the second housing H2 is metal or nonmetal, the second housing H2 has at least a nonmetal area H20 corresponding to a contour of the second radiation member 2.

Next, referring to fig. 1 and 2, and referring to fig. 5, when the first housing H1 and the second housing H2 are in the stacked state shown in fig. 1, a space may be provided between the first housing H1 and the second housing H2, and the first substrate S1, the second substrate S2, the first radiation member 1 and the second radiation member 2 are disposed between the first housing H1 and the second housing H2 and located at one corner between the first housing H1 and the second housing H2. In other words, a space (not shown) is provided between the first housing H1 and the second housing H2, and the first substrate S1, the second substrate S2, the first radiating element 1 and the second radiating element 2 are disposed in the space. Further, as shown in fig. 5, in the first embodiment, a first predetermined distance G1 greater than 0.1 millimeter (millimeter mm) may be provided between the first radiating element 1 and the first housing H1, and a second predetermined distance G2 greater than 5 millimeters may be provided between the second radiating element 2 and the first housing H1. Therefore, since at least one of the first housing H1 and the second housing H2 is made of metal, the radiation efficiency of the first radiation element 1 and the second radiation element 2 can be prevented from being affected by the first housing H1 and/or the second housing H2 by using the structure that the first radiation element 1 is separated from the first housing H1 by a first predetermined distance G1 and the second radiation element 2 is separated from the first housing H1 by a second predetermined distance G2.

In addition, the first radiating element 1 includes a first radiating portion 11 and a feeding portion 10 electrically connected to the first radiating portion 11, and the feeding element 4 includes a feeding end 41 and a grounding end 42. The feeding end 41 is electrically connected to the feeding portion 10 of the first radiating element 1, and the grounding end 42 is electrically connected to the grounding element 3.

For example, the first radiating element 1, the second radiating element 2 and the grounding element 3 may be a metal sheet, a metal wire or other conductive material with conductive effect, the feeding element 4 may be a Coaxial cable (Coaxial cable), and the first substrate S1 and the second substrate S2 may be an FR4 (FLAME RETARDANT 4) substrate, a printed circuit board (Printed Circuit Board, PCB) or a flexible printed circuit board (Flexible Printed Circuit Board, FPCB). Furthermore, it should be noted that the first radiating element 1, the second radiating element 2 and the grounding element 3 may be formed on the first substrate S1 and the second substrate S2 by using a Laser-Direct-Structuring (LDS) technique.

Next, referring to fig. 2 to 5, in the first embodiment, the electronic device may further include a grounding conductive member C, where the grounding conductive member C may be disposed on the grounding member 3, and the grounding conductive member C is electrically connected between the second radiating member 2 and the grounding member 3, so that the grounding member 3 is electrically connected to the second radiating member 2 through the grounding conductive member C. In addition, the grounding conductive member C may abut against an abutment 200 on the second radiating member 2, so that the grounding member 3 is electrically connected to the second radiating member 2. Further, for example, the grounding conductive member C may be a metal elastic member having conductivity, such as a spring or a shrapnel, but the invention is not limited thereto. In addition, in other embodiments, the grounding conductive member C may be disposed on the second radiating member 2, and the grounding conductive member C abuts against the grounding member 3 and is electrically connected between the second radiating member 2 and the grounding member 3. In addition, the grounding conductive member C may also be a protruding portion (not shown) disposed on the second radiating member 2, and the protruding portion disposed on the second radiating member 2 may abut against the grounding member 3, so that the second radiating member 2 and the grounding member 3 are electrically connected to each other. In addition, in another embodiment, the grounding conductive member C may also be a protruding portion (not shown) disposed on the grounding member 3, and the protruding portion disposed on the grounding member 3 may abut against the second radiation member 2. The present invention is not limited by the specific structure of the grounding conductive member C.

Next, referring to fig. 2 to 6, the specific structures of the first radiation element 1 and the second radiation element 2 will be further illustrated, and the following description will be given by taking the usage states of the first radiation element 1, the second radiation element 2 and the grounding element 3 as examples when the first housing H1 and the second housing H2 are in the stacked state shown in fig. 1. In detail, in the first embodiment, the first radiating element 1 may further include a second radiating portion 12 electrically connected to the first radiating portion 11, and the feeding portion 10 is electrically connected between the first radiating portion 11 and the second radiating portion 12. For example, as shown in fig. 6, the first radiating portion 11 may include a first section 111 connected to the feeding portion 10, a second section 112 connected to the first section 111 and turned relative to the first section 111, a third section 113 connected to the second section 112 and turned relative to the second section 112, and a fourth section 114 connected to the third section 113 and turned relative to the third section 113. In addition, the second radiation portion 12 may include a fifth section 121 connected to the feeding portion 10 and a sixth section 122 connected to the fifth section 121 and turned with respect to the fifth section 121.

However, it should be noted that the specific shapes of the first radiator 1 and the second radiator 2 are not limited to the above.

As described above, referring to fig. 6 again, for example, the first section 111 may extend in a first direction (positive Y direction) relative to the feeding portion 10, the second section 112 may extend in a second direction (negative X direction) relative to a connection between the second section 112 and the first section 111, the third section 113 may extend in a third direction (negative Y direction) relative to a connection between the third section 113 and the second section 112, and the fourth section 114 may extend in a fourth direction (positive X direction) relative to a connection between the fourth section 114 and the third section 113. In addition, the fifth section 121 may extend toward a third direction (negative Y direction) with respect to the feeding element 10, and the sixth section 122 may extend toward a fourth direction (positive X direction) with respect to a connection between the sixth section 122 and the fifth section 121.

In one embodiment, the first radiator 1 can generate an operating frequency band with a frequency range between 1710MHz and 2690MHz, and the second radiator 2 can generate an operating frequency band with a frequency range between 698MHz and 960MHz, but the invention is not limited thereto. Further, the second radiation portion 12 generates an operation frequency band higher than that of the first radiation portion 11, and further, the second radiation portion 12 generates an operation frequency band having a center frequency higher than that of the first radiation portion 11. In one embodiment, the first radiating portion 11 can generate an operating frequency band with a frequency range between 1710MHz and 2100MHz, and the second radiating portion 12 can generate an operating frequency band with a frequency range between 2100MHz and 2690MHz, but the invention is not limited thereto.

Furthermore, it should be noted that the second housing H2 has at least a non-metal area H20 corresponding to an outline of the second radiation member 2, and the vertical projection of the second radiation member 2 on the second housing H2 at least partially overlaps the non-metal area H20. Preferably, in another embodiment, the second housing H2 may further include a non-metal area (not shown) corresponding to an outline of the first radiation member 1, and the perpendicular projection of the first radiation member 1 on the second housing H2 at least partially overlaps the non-metal area. It should be noted that, compared to the embodiment of fig. 3, in the embodiment of fig. 7, the slot of the second housing H2 may be filled with a non-metal member to close the slot.

Second embodiment

First, referring to fig. 8 to 10, as can be seen from comparison between fig. 8 to 10 and fig. 2 to 4, the structures of the first radiating element 1 and the second radiating element 2 provided in the second embodiment are different from those of the first radiating element 1 and the second radiating element 2 provided in the first embodiment, i.e. the first radiating element 1 and the second radiating element 2 provided in the second embodiment are disposed on the same surface of the second substrate S2. In addition, it should be noted that other structures of the electronic device U provided in the second embodiment are similar to those of the first embodiment, and are not described herein.

In detail, the electronic device U includes a first radiating element 1, a second radiating element 2, a grounding element 3, and a feeding element 4. The first radiating element 1 includes a first radiating portion 11 and a feeding portion 10 electrically connected to the first radiating portion 11, the second radiating element 2 is coupled to the first radiating element 1 and separated from the first radiating element 1, and the grounding element 3 is electrically connected to the second radiating element 2. The feeding element 4 includes a feeding end 41 and a grounding end 42, wherein the feeding end 41 is electrically connected to the feeding portion 10 and the grounding end 42 is electrically connected to the grounding element 3. Furthermore, the operating frequency band generated by the first radiator 1 is higher than the operating frequency band generated by the second radiator 2. Further, the center frequency of the first operating frequency band is higher than the center frequency of the second operating frequency band. For example, in one embodiment, the first radiator 1 is mainly used for generating an operating frequency band with a frequency range between 1710MHz and 2690MHz, and the second radiator 2 is mainly used for generating an operating frequency band with a frequency range between 698MHz and 960MHz, but the invention is not limited thereto.

Furthermore, the electronic device U may further include a first substrate S1, a second substrate S2, a first housing H1, and a second housing H2, where the first substrate S1 is disposed on the first housing H1, and the second substrate S2 is disposed on the second housing H2. In addition, in the second embodiment, the first radiator 1 and the second radiator 2 are disposed on the same surface of the second substrate S2, and the grounding element 3 may be disposed on the first substrate S1. It should be noted that, the material of the first housing H1 may be metal, the material of the second housing H2 may be metal, and when the material of the first housing H1 is metal, the grounding element 3 may be electrically connected to the first housing H1. However, it should be specifically noted that the second housing H2 has at least a non-metal area H20 corresponding to an outline of the first radiation element 1 and the second radiation element 2, and the vertical projection of the first radiation element 1 and the second radiation element 2 on the second housing H2 at least partially overlaps the non-metal area H20. Preferably, in one embodiment, the area of the vertical projection of the first radiation member 1 and the second radiation member 2 on the second housing H2 is smaller than the area of the non-metal area H20, and the vertical projection of the first radiation member 1 and the second radiation member 2 on the second housing H2 is completely overlapped on the non-metal area H20. In addition, for example, as shown in fig. 9, the non-metal area H20 may be a slot of the second housing H2, however, in other embodiments, a non-metal member may be filled in the slot of the second housing H2, and the present invention is not limited by the forming manner of the non-metal area H20 of the second housing H2.

Next, referring to fig. 8 to 10, and referring to fig. 11 together, the material of the first housing H1 and the second housing H2 is used as metal, the vertical projection of the first radiation member 1 on the first housing H1 at least partially overlaps or completely overlaps the metal region (not numbered in the figure) on the first housing H1, the vertical projection of the second radiation member 2 on the first housing H1 at least partially overlaps or completely overlaps the metal region (not numbered in the figure) on the first housing H1, and the vertical projection of the first radiation member 1 and the second radiation member 2 on the second housing H2 at least partially overlaps the non-metal region H20 on the second housing H2 are illustrated as an embodiment of the present invention. However, it should be noted that in other embodiments, it is also possible that the perpendicular projection of the second radiation member 2 on the second housing H2 at least partially overlaps the non-metal area H20 on the second housing H2, and that the perpendicular projection of the first radiation member 1 on the second housing H2 does not overlap the non-metal area H20 on the second housing H2. That is, with the present second embodiment, the nonmetallic area H20 on the second housing H2 at least partially overlaps with the perpendicular projection of the second radiation member 2 on the second housing H2.

In addition, when the first housing H1 and the second housing H2 are in the stacked state shown in fig. 1, a space is provided between the first housing H1 and the second housing H2, and the first substrate S1, the second substrate S2, the first radiating member 1 and the second radiating member 2 are disposed between the first housing H1 and the second housing H2. Further, as shown in fig. 11, in the second embodiment, a first predetermined distance G1 greater than 0.1 mm is provided between the first radiating element 1 and the first housing H1, a second predetermined distance G2 greater than 5mm is provided between the second radiating element 2 and the first housing H1, and since the first radiating element 1 and the second radiating element 2 are disposed on the second substrate S2, a first predetermined distance G1 greater than 5mm is provided between the first radiating element 1 and the first housing H1. Therefore, since at least one of the first housing H1 and the second housing H2 is made of metal, the radiation efficiency of the first radiation element 1 and the second radiation element 2 can be prevented from being affected by the first housing H1 and/or the second housing H2 by using the structure that the first radiation element 1 is separated from the first housing H1 by a first predetermined distance G1 and the second radiation element 2 is separated from the first housing H1 by a second predetermined distance G2.

Next, referring to fig. 8 to 10, in the second embodiment, since the first radiating element 1 and the second radiating element 2 are disposed on the second substrate S2, and the grounding element 3 is disposed on the first substrate S1, the electronic device U provided in the second embodiment further includes a first conductive element C1 and a second conductive element C2, so that the first conductive element C1 is used to feed in signals and the second conductive element C2 is used to ground.
