Embodiment
Below with reference to accompanying drawing, embodiment of the present utility model and embodiment are described in detail, described specific embodiment in order to explain the utility model, is not to be used to limit embodiment of the present utility model only.
The Bluetooth antenna of portable terminal in the prior art, one of its embodiment, as shown in Figure 1, the antenna body 120 of Bluetooth antenna is arranged on the printed substrate 100 of portable terminal; Utilize printed substrate 100 lip-deep copper layer antenna body 120 cablings are engraved out in corrosion when making the circuit cabling position and the shape covered; Antenna body 120 is put 101 one with the feedback of Bluetooth antenna and is connected, and the Bluetooth chip (accompanying drawing is not shown) on feedback point 101 and the printed substrate 100 electrically connects.
And the Bluetooth antenna of a kind of portable terminal of the present utility model, one of its embodiment, shown in Fig. 2 a, the antenna body 220 of Bluetooth antenna also is arranged on the printed substrate 200 of portable terminal; Also utilize the copper layer that covers on the printed substrate 200 when making the circuit cabling, to corrode the position and the shape of engraving out antenna body 220 cablings; Antenna body 220 is put 201 one with the feedback of Bluetooth antenna and is connected, and the Bluetooth chip (accompanying drawing is not shown) on feedback point 201 and the printed substrate 200 electrically connects; In addition, shown in Fig. 2 b, on printed substrate 200, also be provided with via hole 203; The shape of via hole 203 is preferred but be not limited to circle; The antenna body 220 of Bluetooth antenna via this via hole 203 can be from one side (or one deck) cabling of printed substrate 200 to this printed substrate 200 another side or (another layer), shown in Fig. 2 c; That is to say that the antenna body 220 of Bluetooth antenna can be by carrying out cabling from this via hole 203, in other words, be positioned at printed substrate 200 not the antenna body 220 on the coplanar (or layer) can be connected via this via hole 203.
Compare with the Bluetooth antenna on being arranged on printed substrate 100 in the prior art, this practicality is new provide be arranged on Bluetooth antenna on the printed substrate 200, owing on printed substrate 200, be provided with via hole 203, the antenna body 220 of Bluetooth antenna just can utilize the another side (or another layer) of this via hole 203 from one side (or one deck) cabling of printed substrate 200 to this printed substrate 200, thus under the situation that does not change antenna body 220 length, shared printed substrate 200 spaces of original Bluetooth antenna length have been dwindled greatly, thereby saved more printed substrate 200 spaces, be beneficial on the printed substrate 200 of the confined space, realize more function; Also saved simultaneously the cost of portable terminal.
In the preferred implementation that is arranged in the Bluetooth antenna on the printed substrate 200 that the utility model provides, printed substrate 200 can be the multi-layer sheet of lamina, doubling plate or two-layer above (as 4 to 8 layers etc.); The antenna body 220 of Bluetooth antenna can extend to the opposite side outer surface of printed substrate 200 from a side external surface of printed substrate 200 through this via hole 203.
Perhaps, printed substrate 200 can be doubling plate or two-layer above multi-layer sheet, and the antenna body 220 of Bluetooth antenna can extend to the interlayer face of printed substrate 200 from the outer surface of printed substrate 200 through this via hole 203.
Perhaps, printed substrate 200 can be two-layer above multi-layer sheet, and the antenna body 220 of Bluetooth antenna can extend to another interlayer face of printed substrate 200 from an interlayer face of printed substrate 200 through this via hole 203.
Printed substrate 200 with lamina is an example below, describes concrete enforcement structure and effect thereof that the utility model is arranged on the Bluetooth antenna on the printed substrate 200 in detail.
Because the Bluetooth antenna of portable terminal is the antenna of operating frequency at 2.4G ~ 2.5G, if to satisfy more than 10 meters apart from effect, as shown in Figure 1, in the prior art, cabling is carried out in the space that needs to take about 10mm * 5mm size on the printed substrate 200 at least and wiring could realize.But in the utility model, cabling and wiring are carried out in the space that only need take about 6mm * 3mm on the printed substrate 200, can satisfy more than 10 meters apart from effect; Shown in Fig. 2 b, printed wiring board is provided with circular via hole 203; Shown in Fig. 2 a, be positioned at the antenna body 220 of Bluetooth antenna on the front of individual layer printed substrate 200, from feedback point 201 cablings with when being routed to circular via hole 203, pass the reverse side that circular via hole 203 extends to individual layer printed substrate 200 and carry out cabling and wiring again, perhaps be connected, shown in Fig. 2 c through the antenna body 220 of circular via hole 203 with the Bluetooth antenna of individual layer printed substrate 200 reverse side.To be arranged on Bluetooth antenna on the printed substrate 200 thus again is used on the mobile phone and tests, as following table and shown in Figure 3, the result of test shows, this Bluetooth antenna has been saved more printed substrate 200 spaces, no matter be maximum gain, average gain or directivity curve, this Bluetooth antenna also has higher operating efficiency; Simultaneously, because this Bluetooth antenna is again to be formed by the Copper Foil on the printed substrate 200, so can save the cost of portable terminals such as mobile phone effectively.
