Referring to fig. 1 to 9, it should be noted that the number and shape of the embodiments corresponding to the drawings are merely for illustrating the embodiments of the present invention, so as to facilitate understanding of the present invention, and are not intended to limit the scope of the present invention.
Referring to fig. 1 and 2, the present embodiment discloses an external antenna device 100 for being detachably mounted on an electronic device (e.g., a sharer host). That is, the external antenna device 100 of the present embodiment is different from an antenna (e.g. a mobile phone antenna) disposed inside the electronic device. The external antenna device 100 includes an external socket 1, a housing 2 assembled to the external socket 1, a signal cable 3 passing through the external socket 1 and the housing 2, and an antenna structure 4 disposed in the housing 2 and electrically connected to the signal cable 3. In addition, the antenna structure 4 of the present embodiment is applied to the external socket 1, the housing 2, and the signal cable 3, but the present invention is not limited thereto. The following will respectively describe the construction of each component of the external antenna device 100 according to the present embodiment, and then describe the connection relationship between each component in due course.
As shown in fig. 1 and 2, the external socket 1 is configured to be detachably mounted on the electronic device, and the external socket 1 in this embodiment includes two pipes 11 pivotally connected to each other, and the interiors of the two pipes 11 are mutually communicated.
The housing 2 is elongated, and the housing 2 is formed with a receiving space 21 and a mounting opening 22 communicating with the receiving space 21. Further, the accommodating space 21 can only communicate with the outside via the mounting opening 22. Furthermore, the mounting opening 22 of the housing 2 is detachably connected to the external socket 1, so that the accommodating space 21 of the housing 2 is closed.
The signal cable 3 is partially inserted into the outer socket 1, and the rest part is disposed in the accommodating space 21 of the housing 2. The signal cable 3 includes a free end 31 and a fixed end 32, wherein the free end 31 is disposed on one of the tubes 11 of the external socket 1 for electrically connecting to an electronic device mounted on the external socket 1, and the fixed end 32 is electrically connected to the antenna structure 4.
The antenna structure 4 is disposed in the accommodating space 21 of the housing 2 and is configured to operate in a high frequency band and a low frequency band. The high frequency band and the low frequency band have large bandwidths based on the structure of the antenna structure 4, and the high frequency band is 1710MHz to 2690MHz in the present embodiment, and the low frequency band is 690MHz to 960MHz in the present embodiment, but the present invention is not limited thereto. Further, the antenna structure 4 in this embodiment includes a substrate 41, a ground section 42, an antenna section 43, a matching module 44, a bonding pad 45 (fig. 5), and a low-frequency extension section 46 disposed on the substrate 41.
The substrate 41 is elongated and defines a longitudinal direction D, and the shape of the substrate 41 corresponds to the cross section of the housing 2, so that the housing 2 can be sleeved outside the substrate 41 along the longitudinal direction D. Furthermore, the substrate 41 has a first plate 411 and a second plate 412 located at opposite sides.
As shown in fig. 2 to 4, the grounding section 42 is disposed on the first surface 411 of the substrate 41, and the grounding section 42 is adjacent to the external socket 1. The grounding section 42 of the present embodiment is straight and has a corner 421 away from the outer socket 1. In more detail, the signal path of the ground section 42 is approximately 0.125 times wavelength (i.e., 1/8λ) of the center frequency of the low frequency section, and the signal path of the ground section 42 of the present embodiment is equivalent to the length of the ground section 42 corresponding to the length direction D.
As shown in fig. 2 to 5, the antenna section 43 is disposed on the first surface 411 of the substrate 41, and the antenna section 43 includes a feeding portion 431, a high-frequency antenna portion 432, and a low-frequency antenna portion 433. The high-frequency antenna portion 432 and the low-frequency antenna portion 433 of the present embodiment are disposed at intervals and substantially form a U-shaped profile, the notch of the U-shaped profile faces the ground section 42, and the feeding portion 431 is substantially located in the notch of the U-shaped profile and is adjacent to the ground section 42. Furthermore, one end of the high-frequency antenna portion 432 and one end of the low-frequency antenna portion 433 (i.e. two ends of the U-shaped profile) are located at two opposite sides of the feeding portion 431 and are adjacent to the grounding section 42.
Further, the fixed end 32 of the signal cable 3 is electrically connected to the ground section 42 and the feeding portion 431, and the high-frequency antenna portion 432 and the low-frequency antenna portion 433 are electrically connected to the feeding portion 431 and the ground section 42 via the matching module 44. The matching module 44 of the present embodiment includes a high-frequency microstrip line 441 and a low-frequency microstrip line 442 disposed on the first surface 411 of the substrate 41, and a high-frequency coupling pad 443 and a low-frequency coupling pad 444 disposed on the second surface 412 of the substrate 41.
In more detail, two ends of the high-frequency microstrip line 441 are respectively connected to the feeding portion 431 and the high-frequency antenna portion 432, so as to provide an inductance-like function between the feeding portion 431 and the high-frequency antenna portion 432. The two ends of the low-frequency microstrip line 442 are respectively connected to the ground section 42 and the low-frequency antenna portion 433, so as to provide an inductive component function between the ground section 42 and the low-frequency antenna portion 433. Most of the blocks of the low-frequency microstrip line 442 are located in the unfilled corner 421 of the ground section 42.
Furthermore, the high-frequency coupling pad 443 is electrically connected to the high-frequency antenna portion 432 through at least one first conductive pillar 413 buried in the substrate 41 (that is, two ends of the first conductive pillar 413 are respectively connected to the high-frequency coupling pad 443 and the high-frequency antenna portion 432), and the high-frequency coupling pad 443 can be electrically coupled to the ground section 42, thereby providing a capacitive element-like function between the ground section 42 and the high-frequency antenna portion 432. The low-frequency coupling pad 444 is electrically connected to the feeding portion 431 through at least one second conductive pillar 414 embedded in the substrate 41 (that is, two ends of the second conductive pillar 414 are respectively connected to the low-frequency coupling pad 444 and the feeding portion 431), and the low-frequency coupling pad 444 can be electrically coupled to the low-frequency antenna portion 433, so as to provide a capacitive element between the feeding portion 431 and the low-frequency antenna portion 433.
In addition, the bonding pad 45 is electrically connected to the ground section 42 through at least one third conductive post 415 buried in the substrate 41 (that is, two ends of the third conductive post 415 are respectively connected to the bonding pad 45 and the ground section 42), and the fixed end 32 of the signal cable 3 of the embodiment is soldered to the bonding pad 45 and the low frequency coupling pad 444, so as to be electrically connected to the ground section 42 and the feeding portion 431.
As shown in fig. 3 to 6, the low frequency extension 46 is located away from the outer socket 1, that is, the low frequency extension 46 and the ground 42 are located on opposite sides of the antenna 43 (e.g., the upper side and the lower side of the antenna 43 in fig. 3). The low-frequency extension 46 and the antenna section 43 (the low-frequency antenna 433) have a gap G therebetween, and the size of the gap G is insufficient to affect the electrical coupling of the low-frequency extension 46 to the low-frequency antenna 433. The gap G in the present embodiment is approximately 0.5mm to 1mm in the length direction D, but the present invention is not limited thereto.
Further, the sum of the signal paths of the low frequency extension 46 and the low frequency antenna 433 is approximately 0.375 to 0.625 times the wavelength of the center frequency of the low frequency band. The signal path of the low frequency antenna 433 is approximately 0.125 times the center frequency of the low frequency band, and the signal path of the low frequency extension 46 is approximately 0.125 times to 0.375 times the center frequency of the low frequency band. It should be noted that, the signal path of the low-frequency extension 46 is in a straight strip shape in the present embodiment and is substantially equal to the length of the low-frequency extension 46 corresponding to the length direction D, and the signal path of the low-frequency extension 46 in the present embodiment is preferably 0.375 times the center frequency of the low-frequency band, but is not limited thereto.
In addition, the low frequency extension 46 shown in fig. 3 is illustrated as a straight bar, but the shape of the low frequency extension 46 can be adjusted according to the needs of the designer. For example, as shown in fig. 7, the low-frequency extension 46 may also be bent (i.e., the signal path of the low-frequency extension 46 is bent), so that the signal path of the low-frequency extension 46 providing signal operation is unchanged, but the length of the low-frequency extension 46 corresponding to the length direction D can be shortened, thereby facilitating the application on the shorter substrate 41. That is, the signal path of the low-frequency extension 46 shown in fig. 7 is greater than the length of the low-frequency extension 46 corresponding to the length direction D.
The grounding section 42, the feeding section 431, the high-frequency antenna section 432, the low-frequency antenna section 433 and the low-frequency extension section 46 shown in fig. 3 are all illustrated as being disposed on the first surface 411 of the substrate 41, but the present invention is not limited thereto. For example, as shown in fig. 8, the low-frequency extension 46 may also be disposed on the second surface 412 of the substrate 41, and a portion of the low-frequency extension 46 is located below the low-frequency antenna 433 and can be electrically coupled to each other.
In summary, the external antenna device 100 and the antenna structure 4 thereof disclosed in the present embodiment are electrically coupled to the low-frequency extension 46 through the low-frequency antenna portion 433, so that the signal path provided by both the external antenna device and the antenna structure is approximately 0.125-0.375 times the center frequency of the low-frequency band, thereby improving the antenna gain of the antenna structure 4 (e.g. the antenna gain of the antenna structure 4 during the operation of the low-frequency band and the high-frequency band is maintained above approximately 3 dBi) and enabling the applicable frequency band of the antenna structure 4 to have a larger bandwidth (as shown in fig. 9).
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, but all equivalent changes and modifications according to the claims of the present invention shall fall within the scope of the claims.
