DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1A and 1B, an antenna assembly 30 according to a first embodiment of the present invention is shown, which includes a plurality of wireless signal transceivers 31 and at least one positioning plate 32. The number of the wireless signal transceivers' 31 is determined according to actual requirements. Each of the wireless signal transceivers 31 has a base 33 and a transmitting and receiving portion 34 disposed on the base 33, and each base 33 is fixed to the positioning plate 32. The transmitting and receiving portions 34 are used to transmit or receive wireless signals, such that the wireless signal transceivers 31 function normally in corresponding frequency ranges. Each of the bases 33 has a fixing hole 331 formed on a side surface thereof. One end of the transmitting and receiving portion 34 is screwed or inserted into the fixing hole 331. The base 33 and the transmitting and receiving portion 34 can also be formed monolithically, or the transmitting and receiving portion 34 is disposed inside the base 33. The other side of each of the bases 33 has a fixing portion 332, and the positioning plate 32 has a positioning portion 321 corresponding to the fixing portion 332. The fixing portion 332 includes a plurality of positioning posts 332A, and the positioning portion 321 has a plurality of corresponding positioning holes 321A. The positioning posts 332A are inserted into the positioning holes 321A, so as to make fixing portion 332 being coupled to the positioning portion 321, and further to fix the base 33 to positioning plate 32 (as shown in FIG. 7B). Thus, the plurality of wireless signal transceiver 31 is combined into the antenna assembly 30. The combination of the plurality of wireless signal transceiver 31 enhances the intensity of transmitting and receiving the wireless signals, or enables the wireless signal transceivers 31 to work at different frequencies, thereby improving the transmission bandwidth of the entire antenna assembly 30, and increasing the data transmission rate. The transmitting and receiving portions 34 of the wireless signal transceivers 31 are spaced at predetermined distances according to characteristics of the wireless signals, such that the wireless signal transceivers 31 do not interfere with one another in operation.
Referring to FIGS. 1A and 1B again, when the present invention is applied, the fixing portion 332 of the base 33 of each of the wireless signal transceivers 31 is attached towards the positioning portion 321 of the positioning plate 32. The positioning posts 332A of the fixing portion 332 are inserted in the positioning holes 321A, so as to fix the base 33 to the positioning plate 32. Moreover, the projected area of the base 33 is slightly smaller than the area of the positioning plate 32, such that one of the wireless signal transceivers 31 is fixed at the middle of the positioning plate 32. At this time, the positioning plate 32 will protrude relative to an edge of the base 33 of this wireless signal transceiver 31. When it is desired to increase the number of the wireless signal transceivers 31, the wireless signal transceivers 31 are sequentially fixed on the periphery of the positioning plate 32, such that the opposite sides of the bases 33 are abut to one another, thereby realizing the effect of adding the wireless signal transceivers 31 flexibly (as shown in FIG. 1B). The bases 33 are in the shape of a regular polygon, but are not limited to be so.
Referring to FIG. 2, an antenna assembly 30 according to a second embodiment of the present invention is shown, which includes a plurality of wireless signal transceivers 31 and at least one positioning plate 32. The overall structure of the second embodiment is similar to that of the first embodiment, while the difference lies in that the fixing portion 332 of each of the bases 33 has a plurality of positioning holes 332B, and the positioning portion 321 of the positioning plate 32 has a plurality of corresponding positioning posts 321B. The positioning posts 321B of the positioning plate 32 engaged in the positioning holes 332B of the base 33, so as to fix the base 33 to the positioning plate 32.
The present invention has disclosed the engagement design of the positioning plate in the first and the second embodiments, while the configuration of the positioning plate naturally is not limited to the engagement. Therefore, a screw design of the configuration of the positioning plate is further disclosed as a third embodiment of the present invention.
Referring to FIGS. 3A and 3B, an antenna assembly 30 according to the third embodiment of the present invention is shown, which also includes a plurality of wireless signal transceivers 31 and at least one positioning plate 32. The overall structure of the third embodiment is also similar to that of the first embodiment, while the difference lies in that the antenna assembly 30 further includes a plurality of fixing members 40. Furthermore, the positioning portion 321 and the fixing portion 332 further have bolt holes 321C and 332C respectively. Therefore, when attaching the fixing portion 332 of the base 33 towards the positioning portion 321 of the positioning plate 32, the fixing members 40 pass through the bolt holes 321C and 332C respectively, i.e., the fixing members 40 pass through the positioning portion 321 and are fixed to the fixing portion 332, so as to fix the base 33 to the positioning plate 32 (as shown in FIG. 3B). The fixing members 40 are screws, but are not limited to be screws.
As the projected area of each of the bases is slightly smaller than the area of the positioning plate, and the shape of the positioning plate is not limited to be the regular polygon of the first embodiment, but can be in different arranging configurations according to the requirements of the communication specifications. Therefore, an antenna assembly is further described as a fourth embodiment of the present invention.
Referring to FIG. 4A, an antenna assembly 30A includes a plurality of wireless signal transceivers 31A and at least one positioning plate 32A. The structure and composition of the fourth embodiment is also similar to that of the first embodiment, while bases 33A are in a triangular shape, and do not contact one another, and the shape of the section of transmitting and receiving portions 34A is also different from the shape of the base 33A.
Referring to FIG. 5, an antenna assembly 30 according to a fifth embodiment of the present invention is shown, which includes a plurality of wireless signal transceivers 31 connected with one another. Each of the wireless signal transceivers 31 has a base 33 and a transmitting and receiving portion 34 disposed on the base 33. A first engaging portion 335A and a second engaging portion 335B matching with each other are arranged on sides of each of the bases 33. The first engaging portion 335A and the second engaging portion 335B are an engaging block and an engaged hole matching with each other. The first engaging portion 335A of a wireless signal transceiver 31 is engaged with the second engaging portion 335B of another wireless signal transceiver 31, so as to combine the two wireless signal transceivers 31. Thus, the antenna assembly 30 of this embodiment is formed by combining the plurality of wireless signal transceivers 31 sequentially.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
