Description
Technical field
The present invention relates to antenna technical field, specially a kind of SMA linkings 3G antennas.
Background technology
With informationization, networking, intelligentized universal, various equipment have prodigious want for the receptivity of signal
It asks, especially wireless signal.The transmission of wireless signal is completed by the transmission of electromagnetic wave.Electromagnetic wave propagation is not resonable
The free space thought carries out, but is transmitted in certain medium, influence of the different media to radio wave be it is different,
In common transmission range, the loss of wave transmissions is also very big.
The function of antenna is exactly to radiate and receive radio wave, is electromagnetic wave high frequency current transitions when transmitting；It receives
When, electromagnetic wave is converted to high-frequency current.So the major technique of antenna includes：
1. antenna will be there are one electromagnetism open system, antenna should complete the mutual of guided wave energy and electromagnetic wave energy as far as possible
Conversion；
2. antenna is matched with transmitter or receiver；
3. antenna will have directionality, electromagnetic wave concentrates on as far as possible to be determined on direction, or the incoming wave maximum limit to determining direction
Degree receives；
4. antenna has polarization appropriate, it can emit or receive to provide polarized electromagnetic wave；
5. antenna should have enough working bands.
But existing antenna structure is complicated, still has some deficits in Adapter Property performance.
Invention content
It is compact-sized the purpose of the present invention is to provide a kind of SMA linkings 3G antennas, it can more preferably be adapted to environment position
Demand.
To achieve the above object, the present invention provides the following technical solutions：A kind of SMA linkings 3G antennas, including corner one
Body formula SMA connectors, rod set, signal spring；Described rod set one end is Closed Head, the other end equipped with counterbore, the corner
Integral type SMA connectors include thread ontology and the first connecting pin being connected with thread ontology, second connection end, the first connection
End is column structure, and column structure is connected equipped with annular projection with riveting at the rod set counterbore along outer wall, second connection
End is internal thread interface, and the first connecting pin, second connection end are vertical setting；The signal spring-compressed is arranged in rod set,
Signal spring one end is closed the limit of formula head, the other end is connected with the center of the column structure.
Above-mentioned technical proposal is further improved, the second connection end is to set female outer-hexagonal bolt, in internal
The heart is equipped with center needle.
Further, the thread ontology is the cube shape structure equipped with circular cavity, and tack spiral shell is equipped in circular cavity
Nail.
Further, the Closed Head of the rod set is arc-shaped.
Further, the rod set length is 42 ± 0.2mm, a diameter of 8 ± 0.1mm.
Compared with prior art, the beneficial effects of the invention are as follows：
1, structure of the invention is compact, and low-profile is beautiful, and small equipment is required size suitable for some；
2, it can be rotated without dead angle with 360 degree after there is corner integral type SMA connectors unique internal structure, antenna to fix,
More preferable adaptation environment locational requirement, easy to operate, stabilized structure；Corner integral type SMA connectors, which have, is threadedly coupled port, tears open
It unloads convenient and efficient；
3, rod set and SMA connector rivetings connect, simple for process, and reliability is high；
4, perfection accomplishes that low-loss, high-gain, 360 ° of spherical shapes of omnidirectional are covered using inner antenna space to the reception and transmitting of signal
Lid antenna, frequency range can accomplish 690-960MHZ&1710-2700MHZ.
