Scalable thimble mode is welded on PCBA, so as to during fastening component, realize that antenna feeds pin to PIFA aerial panels
Be in contact so that by the satellite positioning signal received by antenna feed pin, be connected on PCBA, at active circuit
Reason.Corresponding thimble summit can be set for different antenna mounting pin, if not needing antenna mounting pin in practice, be not required to
Corresponding thimble summit is set for antenna mounting pin.In specific implementation process, thimble is welded on PCBA, and thimble is band bullet
Spring or shell fragment have a scalable thimble, and PCBA is longer than in its natural state to the distance of aerial radiation piece.The feedback of PIFA antennas
Electric pin and short-circuited conducting sleeve grounding leg is good contact point on aerial radiation piece, when locking metallic shield lid, is covered and aerial radiation
During the sealing waterproof plastic lid of piece integration, thimble is tightly withstood on the contact point of feed pin and short-circuited conducting sleeve grounding leg.This design
Scheme simplifies mounting process, will become more convenient, and ensure that reliability.
Integration PIFA antenna structure views as shown in fig. 13 that, its aerial radiation piece and metal screen in PIFA antennas
Cover and plastic filler is provided between covering, it is specifically included：PIFA antennas 121, metallic shield lid 122 and PCBA124 etc., in PIFA
There is plastic filler 123 between the aerial radiation piece and metallic shield lid 122 of antenna 121, in aerial radiation piece 122 and metal screen
Cover increase plastic filler 21 between lid 4, it is possible to increase the bandwidth of antenna so that antenna performance is more excellent.Further optimization,
Plastic filler 123 is fixed on the surface of metallic shield lid 122, is filled out while the aerial radiation piece of PIFA antennas is also close to fixed plastics
Fill thing 123 so that metallic shield lid 122, plastic filler 123 and the integration of aerial radiation piece, the benefit of this design method is
It is convenient during installation, and PIFA antennas have support to become more to consolidate.
It should be noted that plastic filler involved in Figure 13 goes for any PIFA and metallic shield lid phase
With reference to pattern in, it is only necessary between PIFA antennas and metallic shield lid have additional space accommodate plastic filler.
LNB modules involved by the utility model embodiment, it includes integral antenna module and involved metallic object, close
Waterproof plastic lid, outer packing plastic housing cover etc. are sealed, the integral antenna module is fixed on metallic object, seal waterproof plastic lid lid
In integral antenna module, the part that metallic object is formed with integral antenna module and sealing waterproof plastic lid, Ke Yitong
Cross outer packing plastics clamshell cover.Based on the contrast shown in Fig. 1 and Fig. 2 it is known that the integrated day that the LNB modules are used
Wire module can reduce the area in the region 8 shown in Fig. 2, so that LNB module volumes are smaller.
Integrated PIFA Anneta modules as shown in figure 14, it includes：PIFA antennas 144, sealing waterproof plastic lid 143,
Metallic shield lid 142 and PCBA141.Because the final PCBA of LNB modules needs to do waterproofing design, and need to ensure PIFA days
Line can receive satellite positioning signal.So sealing waterproof plastic lid would generally be covered, and sealing water-proofing treatment is made in dispensing.This practicality
The aerial radiation piece 18 of new involved PIFA antennas is fixed in the interior top plane of sealing waterproof plastic lid 2, now antenna
Radiation fin 18 is integrated with sealing waterproof plastic lid 2.The feed pin and short-circuited conducting sleeve grounding leg 146 of antenna are drawn, works as waterproof
When vinyl cover 143 covers metallic shield lid 142 and PCBA141, i.e. flat cover on LNB metallic objects, the radiation fin of antenna will be with gold
Belong to screening cover plane parallel, form PIFA antennas.The distance and putting position of the short-circuit pin of adjustment and feed pin are adjusted antenna
Impedance.The feed pin of PIFA antennas passes through the through hole 145 that metallic shield is covered with short-circuited conducting sleeve grounding leg, finally and PCBA141
It is connected.
Similarly, as shown in figure 15, metallic shield lid can make open slotted eye so that the feed pin of PIFA antennas and
Short-circuited conducting sleeve grounding leg and support feet are exposed in metallic shield lid in metallic shield lid outward flange, are finally connected with PCBA.This sets
The benefit of meter mode is more facilitated when welding the feed pin and short-circuited conducting sleeve grounding leg of PIFA antennas with support feet, assembling gold
More facilitate when belonging to screening cover.
It should be noted that for integration PIFA Anneta modules, antenna feed pin may be also secured at metallic shield lid
On through hole on, can by antenna feed pin be provided at both ends with scalable thimble, in integrated ceramic antenna fastener cycle, should
The scalable thimble one end at antenna feed pin two ends withstands on the antenna feed point of ceramic antenna, and the other end withstands on PCBA pad
On, this mounting means is also more convenient, has also ensured that ceramic antenna is reliably connected with PCBA.
It should be noted that for integration PIFA Anneta modules, antenna feed pin can be fixed on metallic shield lid
On through hole, a Plug pin patch bay is welded on PCBA pad, a Plug pin patch bay is welded on antenna feed point, in integral antenna module
In fastener cycle, antenna feed pin one end is inserted on the Plug pin patch bay of pad, and the other end is inserted in the Plug pin patch bay on antenna feed point
On, this mounting means is also more convenient, has also ensured that ceramic antenna is reliably connected with PCBA.
It should be noted that for integral antenna module, antenna can be fed pin and antenna feed point is welded,
Antenna feed pin has chip architecture of the spring, and chip architecture of the spring passes through the through hole or slotted eye that metallic shield is covered, and withstands on
On PCBA pad；Or antenna feed pin and pad solder one, antenna, which feeds pin, has chip architecture of the spring, chip architecture of the spring
The through hole or slotted eye covered through metallic shield, and withstand on the antenna feed point.This chip architecture of the spring is relatively good to be applicable
In the antenna feed pin of PIFA antennas.
To sum up, the integral antenna module in the utility model reduces PCBA size, so as to reduce the gold in LNB
Category body, waterproof sealing vinyl cover, the size of outer packing plastic jacket are also accordingly reduced, and finally realize the reduction of LNB costs.
