Embodiment

At first see also Fig. 1～Fig. 3, the dipole antenna of the utility model one embodiment mainly comprises a substrate 10, one first antenna body 21 and one second antenna body 22, wherein first,

second antenna body

21,22 is a metallic conductor for example, and is formed on the substrate 10.As Fig. 1～shown in Figure 3, aforesaid base plate 10 is roughly rectangular and extend towards a major axis C1 direction, wherein on substrate 10, be provided with at least one first perforation, 211 and 1 second perforation 221, mainly be provided with two first perforation 211 on the substrate 10 of present embodiment, the high-temperature gas that this design is produced when helping making welding is discharged by first perforation 211, and then can increase the adaptation of welding.Will be appreciated that aforementioned first antenna body 21 extends to the second side S2 of substrate 10 by the first side S1 of substrate 10 through first perforation 211, and the interior sidewall surface of first perforation 211 and peripheral region are all by 21 coatings of first antenna body; Accordingly, aforementioned second antenna body 22 extends to the second side S2 of substrate 10 by the first side S1 of substrate 10 through second perforation 221, and the interior sidewall surface of second perforation 221 and peripheral region are all by 22 coatings of second antenna body.

What need special instruction is, substrate 10 definables in the present embodiment go out a center line C2, aforementioned center line C2 is perpendicular to major axis C1 direction, first,

second antenna body

21,22 is formed at the both sides of center line C2 respectively, and both positions are symmetrical, in addition both shapes and area (as shown in Figure 1) then about equally.As seen from Figure 1, first,

second antenna body

21,22 forms the rectangular configuration of a hollow respectively at the first side S1 of substrate 10, one first distance D 1 of wherein being separated by between the rectangular configuration of two hollows, the scope of aforementioned first distance D 1 is approximately between 0.8～1.2mm (for example can make the first distance D 1=1mm).

Please continue to consult Fig. 1, aforementioned first,

second antenna body

21,22 is being near being formed with first, second protuberance 210,220 respectively on the side of center line C2, and wherein first, second protuberance 210,220 roughly protrudes and is symmetrical in center line C2 along major axis C1 direction.See also Fig. 3 again, first,

second antenna body

21,22 is formed with a rectangle and circular configuration respectively on the second side S2 of substrate 10, can cover first, second perforation 211,221 circumferential surface thus, can help simultaneously dipole antenna and be electrically connected, and then finish whole assembly program with spindle guide line together.

Fig. 4～Fig. 6 represents the schematic diagram that aforementioned dipole antenna is electrically connected with spindle guide line 40 together; wherein the protection crust of concentric conductor 40 front ends (protective jacket) divests in advance, and exposes netted conductor 41 (conducting mesh or sleeve), insulating barrier 42 (insulator) and core 43 (conductingcore) partly.As Fig. 4, shown in Figure 5, concentric conductor 40 can be attached at the second side S2 of substrate 10 during assembling, and concentric conductor 40 is extended towards the major axis C1 direction of substrate 10, wherein the core 43 of concentric conductor 40 front ends is aimed at second perforation 221; Then, can utilize scolding tin that the core 43 of concentric conductor 40 front ends is welded on second antenna body 22 around second perforation 221 so that both formation electrically conduct (as shown in Figure 6), netted conductor 41 can be welded in addition on first antenna body 21 around first perforation 211 so that both formation electrically conduct.
