It enough generates multipath current and forms fixed skew, then enabled current in the horizontal direction by the helical structure 22
It is distributed on upper and vertical direction, to realize circular polarisation.Since the antenna sheet 20 is arranged along the connection side 11 of the substrate 10,
So as to save occupied space of the antenna sheet 20 on the substrate 10, and then the headroom of the substrate 10 can be reduced
While region, it is also possible that the circular polarized antenna 100 is compact-sized.
Specifically, the substrate 10 is rectangular substrate, and the substrate 10 is epoxy glass cloth laminated board (FR4),
So that the substrate 10 can have good anti-flammability and stable electrical insulation capability.Due to the circular polarized antenna
100 are set to inside the apparatus body, so the size of the substrate 10 can be arranged according to the volume of the apparatus body.It is described
Connect the long side that side 11 is the substrate 10.
The substrate 10 further includes empty regions 12 and routing region 13, and the antenna sheet 10 is set to the empty regions
12.In the present embodiment, the empty regions 12 are that the length direction along the connection side 11 extends, and towards the substrate 10
The square region that width direction extends.Since the antenna sheet 20 is arranged along the connection side 11, so the day can be reduced
Occupied space of the line piece 20 on the substrate 10, so that the area of the empty regions 12 can greatly reduce.That is, institute
The area for stating routing region 13 can increase accordingly, to increase the wiring space on the substrate 10.Preferably, described net
The width 3mm of empty region 12.It is understood that in other embodiments, the width of the empty regions 12 can also be according to institute
State the facilities adjustment setting of the size and the antenna sheet 20 of substrate 10.
The vertical substrate 10 of the antenna sheet 20 is arranged.In the present embodiment, the antenna detail 21 is bonded the substrate
10 connection side 11 is arranged, connection side 11 of the helical structure 22 perpendicular to the substrate 10.
The antenna detail 21 further includes feed line 213 and short-circuit line 214, the feed line 213 and the short circuit
One end of line 214 is connect with the horizontal part 211 of antenna detail 21, and the feed line 213 and the short-circuit line
214 other end is connect with the substrate 10.In the present embodiment, due to the feed line 213 and the short-circuit line 214
One end is connect with the horizontal part 211 respectively, so the feed line 213, the short-circuit line 214 and the antenna detail 21
Between the substrate 10 relatively form an inverted f character form structure, so as to form multipath current on the antenna detail 21.
In the present embodiment, the feed line 213 is bending cable architecture, including the first feedback connecting with the horizontal part 211
Electric portion 213a and the second current feed department 213b for being vertically connected at the substrate 10, and the second current feed department 213b and institute

The antenna sheet 20 is grounded with realizing, prevents 20 short circuit of antenna sheet.Preferably, the short-circuit line 214 is straight line, thus
The short-circuit line 214 can be reduced the distance between to the routing region 13, that is, the face of the empty regions 12 can be reduced
Product, greatly reduces the occupied space of the substrate 10.
In the present embodiment, the antenna detail 21 further include with the vertically disposed vertical portion 215 of the horizontal part 211, and
And the vertical connection side 11 in the vertical portion 215 is arranged.The antenna detail 21 can be in the horizontal part 211 and described
Multipath current is formed on vertical portion 215, in order to the subsequent circular polarisation for realizing the antenna sheet 20.
Spire 221 of the helical structure 22 including multiple successively nestings, and two adjacent spires 221
Between have gap.In the present embodiment, the helical structure 22 is clip structure, so that the circular polarized antenna 100
It can be realized miniaturization, be conducive to be installed in the electronic equipment.The spire 221 is gone up and the level in the horizontal direction
Portion 211 has the gap, and the upper and vertical portion 215 has the gap to the spire 221 along the vertical direction.By
There is the horizontal direction for being parallel to the horizontal part 211 simultaneously and have in the spire 221 and be parallel to the vertical portion
215 vertical direction, so enabled on the helical structure 22 electric current and meanwhile in the horizontal direction and vertical direction into
Row distribution.Further, since between described in being all had between the spire 221 and the horizontal part 211 and the vertical portion 215
Gap so that the electric current can due to the gap effect and form multipath current.
Further, due to having the fluting gap 23 between the helical structure 22 and the antenna detail 21, and
And the gap is all had between two adjacent spires 221, so that formed on the helical structure 22
The current distribution in current distribution and vertical direction in horizontal direction can be carried out by the fluting gap 23 and gap
Change, multipath current is formed, so that the antenna sheet 20 there can be 90 ° of phase difference, to realize circular polarisation.It is preferred that
Ground, the fluting gap 23 is 0.1mm, so as to avoid causing not coupling since the fluting gap 23 is excessive
The performance issue of the antenna sheet 20 is influenced, it is also possible to avoid that reality can not be processed since the fluting gap 23 is too small
It is existing.
