Description
Technical field
The present invention relates to a kind of intelligent machine antenna applied to all-metal ring under, specifically a kind of all-metal ring
Narrow frame 4G intelligent machine antennas, belong to wireless communication antenna technical field.
Background technology
With communication system continuing to develop from 1G to 4G, the frequency range of covering also increases therewith required for modern smart mobile phone
Plus, GSM850/900/DCS/PCS/UMTS2100/LTE2300/2500 working frequency range is covered, for conventional internal placed man
For machine antenna, so many and wide frequency range is a very big challenge all the time.Although the system board of modern smart mobile phone is got over
Come bigger, but increased chip and other modules with amusement function, such as camera, MP3 and some sensors therewith
Etc. the most spaces for occupying floor, the space for leaving antenna for is less and less, is set so miniaturization is always antenna for mobile phone
The requirement of meter, but with the increase of communications band, the communications band to be covered is very wide, and this undoubtedly adds the realization of miniaturization
Difficulty, but nowadays people also cause the design of antenna to become more difficult the continuous requirement for shielding accounting.
Except in the case of described above, the metallization of smart mobile phone shell in the last few years turns into current trend, from
Iphone4 starts, and possesses the intelligent machine of metal edge frame and almost turns into the standard configuration that each cell phone manufacturer produces new machine.But in order to ensure
The performance of antenna for mobile phone, will typically be disconnected complete becket by gap, and regard a part therein as the one of antenna
Part, but so do, script becket aesthetic property and metal strength have been not only broken up, also the performance of antenna has been held by hand
In the case of performance be difficult to be ensured.
The content of the invention
Seven frequency range 4G coverings just can be realized the technical problem to be solved in the present invention is to provide a kind of metal structure of not destroying
The all-metal ring narrow frame 4G intelligent machine antennas of narrow frame.
In order to solve the above-mentioned technical problem, all-metal ring narrow frame 4G intelligent machine antennas of the invention, including PCB
And the system floor positioned at PCB surface, PCB periphery is surrounded with becket, becket and PCB it
Between there is gap, be provided with the feed port that becket is divided into two loop antennas, the basic mode of two loop antennas on becket
Six frequency ranges are collectively covered with higher mode, in addition to one is used for the grounded metal sheet that is grounded and one by capacity cell and electricity
The match circuit that sensing unit parallel connection is constituted, the match circuit is arranged between grounded metal sheet and system floor；Becket with
Match circuit collectively constitutes the radiating element of antenna, and the self-resonance of capacity cell and inductance element influences double loop antenna at low frequency
Input impedance value, make its frequency range of low frequency resonance point increase.
The top and bottom of the PCB are provided with the headroom adjusted for antenna match.
The empty regions width is 5mm.
After above-mentioned structure, the antenna is using the becket, the match circuit that are divided into two loop antennas, and antenna is in itself
Six frequency ranges can be covered；Match circuit is constituted by a capacity cell is in parallel with an inductance element, and produced influence can make
Double loop antenna covers seven frequency ranges together, and applied to all-metal ring under, metal structure is not destroyed just can realize seven frequency range 4G
Covering, the problem of efficiently solving between antenna performance and all-metal ring solves all-metal ring and surrounds lower 4G intelligent machine antennas
Performance poor problem excessively, PCB has the clearance zone of small width in upper and lower side, meets the requirement of narrow frame, solves complete
The technical barrier of high screen accounting is designed under becket limitation, its frequency band is more, and radiation efficiency is high, and narrow frame is maintained complete
Becket is not damaged, and is highly suitable for modern cell phones.

Embodiment
With reference to the accompanying drawings and detailed description, the all-metal ring narrow frame 4G intelligent machine antennas of the present invention are made into one
Step is described in detail.
As illustrated, the all-metal ring narrow frame 4G intelligent machine antennas of the present invention, including PCB 1 and positioned at PCB
The system floor 2 of circuit board surface, the periphery of PCB 1 is surrounded with becket 8, and becket is that thickness is 0.3mm, is highly
5mm copper sheet is made, and has gap 3 between becket 8 and PCB 1, the top and bottom of PCB 1 are respectively provided with
There is the headroom adjusted for antenna match, empty regions width is 5mm, meets the requirement to narrow frame mobile phone；Set on becket 2
The feed port 4 that becket is divided into two loop antennas is equipped with, basic mode and the higher mode of two loop antennas collectively cover six
Frequency range, in addition to one be used for the grounded metal sheet 5 that is grounded and one is constituted by capacity cell 6 is with inductance element 7 in parallel
The two ends of match circuit, specifically capacity cell 6 and inductance element 7 are also respectively provided with a piece of connection sheet metal, connection gold
Complete becket is separated into two loop antennas by category piece with feed minor matters, and feed minor matters are directly presented on becket, match circuit
It is arranged between grounded metal sheet 5 and system floor 2；Becket 8 collectively constitutes the radiating element of antenna, electric capacity with match circuit
The self-resonance of element 6 and inductance element 7 influences input impedance value of the double loop antenna at low frequency, makes it in the frequency range of low frequency
Resonance point increase, i.e., cover seven required frequency ranges together with the frequency range covered with double loop antenna, thus becket and
Under collective effect with circuit, seven work frequencies of GSM850/900/DCS/PCS/UMTS2100/LTE2300/2500 are covered
Section.
By it was verified that Fig. 4 represents emulation and material object S11Parameter compares figure, it can be seen that policy and the result one of actual measurement
Cause, and matching is good, Fig. 5 represents object test efficiency and gain diagram, and its value illustrates that this antenna meets application demand.
