Description
Technical field
The present invention relates to a kind of antenna and preparation method thereof, particularly relate to a kind of three-dimensional antenna and preparation method thereof.
Background technology
Flourish along with wireless transmission brings various product and the technology that are applied to the multifrequency transmission simultaneously, and therefore many new products can have the performance of wireless transmission, so as to satisfying consumer's information transmission demand.And in wireless transmitting system, antenna is to be used for launching and receiving one of critical elements of electromagnetic wave energy, if lack antenna, then wireless transmitting system will be launched and the reception data.Therefore, the role of antenna is an indispensable ring concerning wireless transmission.
In wireless transmission, more general frequency band standard has IEEE 802.11 and IEEE802.15.1 (bluetooth communication) or the like at present, and wherein, IEEE 802.11 divides into standards such as IEEE 802.11a, IEEE802.11b and IEEE 802.11g again.IEEE 802.11a is the standard at the 5GHz frequency band; IEEE 802.11b and IEEE 802.11g are the standard at the 2.4GHz frequency band; IEEE 802.15.1 also is the standard at the 2.4GHz frequency band.
For meeting above-mentioned standard, three-dimensional antenna is present common wherein a kind of antenna kenel.See also shown in Figure 1A to Fig. 1 E, below will sketch the manufacture method of existing three-dimensional antenna, it comprises step 1 to step 8.
Shown in Figure 1A, step 1 provides another long limit 11 ' of one having a long limit 11, being parallel to each other with long limit 11, a minor face 12 and the rectangular metal sheet 1 of another minor face 12 ' of being parallel to each other with minor face 12.
Shown in Figure 1B, step 2 is that the long limit 11 by rectangular metal sheet 1 forms one first crack 13 parallel with minor face 12; Step 3 is that the long limit 11 by rectangular metal sheet 1 forms one second crack 14 parallel with first crack 13 and that have equal length, and wherein, 14 zone definitions is a feeding portion 21 between first crack 13 and second crack; Step 4 is that the minor face 12 by rectangular metal sheet 1 forms one the 3rd crack 15 that the end with first crack 13 links, and removes segment rectangle sheet metal 16; Step 5 is that another minor face 12 ' that the minor face 12 by rectangular metal sheet 1 is parallel to each other forms one the 4th crack 17 that the end with second crack 14 links, and removes another part rectangular metal sheet 18.
Shown in Fig. 1 C, be a grounding parts 22 by the minor face 12 of sheet metal and apart from the formed zone definitions of minor face 12 1 distance D, and will be a Department of Radiation 23 except the zone definitions grounding parts 22 and the feeding portion 21.
Shown in Fig. 1 D, step 6 be with feeding portion 21 along direction bending 90 degree parallel with another long limit 11 ', and with grounding parts 22 along direction bending 90 degree parallel with another minor face 12 '.Then, step 7 is to place a back-up block F between a printed circuit board (PCB) 24 and Department of Radiation 23, so that a printed circuit board (PCB) 24 be arranged in parallel with Department of Radiation 23, make feeding portion 21 and grounding parts 22 firmly to contact with printed circuit board (PCB) 24, and can not tilt with respect to printed circuit board (PCB) 24, and then cause follow-up welding to be difficult for because of feeding portion 21 and grounding parts 22.
Shown in Fig. 1 E, step 8 is feeding portion 21 and grounding parts 22 are utilized welding respectively and to electrically connect with printed circuit board (PCB) 24, and back-up block F is taken out, to finish the making of three-dimensional antenna.
Yet, the segment rectangle sheet metal that manufacture method removed 16,18 (scrap metal) (shown in Figure 1B) of above-mentioned three-dimensional antenna accounts for 20～35% of whole rectangular metal sheet, in other words, effective utilization zone of rectangular metal sheet 1 has only accounted for 65～80%, remaining part has then slatterned, and causes the increase of material cost.In addition, feeding portion 21 and grounding parts 22 only see through an end 221 of end 211 of feeding portion 21 and grounding parts 22 and electrically connect (shown in Fig. 1 D) with printed circuit board (PCB) 24, because its contact area is little, cause in the use of manufacturing process or subsequent product, feeding portion 21 and grounding parts 22 separate with printed circuit board (PCB) 24 easily, and then influence product quality.
This shows that above-mentioned existing three-dimensional antenna and preparation method thereof obviously still has inconvenience and defective, and demands urgently further being improved in product structure, manufacture method and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of new three-dimensional antenna and preparation method thereof, just become the current industry utmost point to need improved target.
