Believe terminal.
Background technology
For office PAD, large-sized communication terminal such as smart television, the communication function being compatible with is also increasingly
It is more.
The motherboard size of the communication terminal of large scale type is also larger, causes the reference ground size of large scale product often remote
Much larger than the half-wavelength of frequency range needed for antenna, this can not play with causing antenna reference to aerial signal well excite ask
Topic, causes antenna launching efficiency relatively low.
Invention content
This application provides a kind of antenna assembly of communication terminal and communication terminals, solve existing large scale communication terminal
The relatively low technical problem of antenna launching efficiency.
In order to solve the above technical problems, the application is achieved using following technical scheme：
It is proposed that a kind of antenna assembly of communication terminal, including signal source and antenna, the signal source connect the antenna；Further include
Main reference ground, antenna reference and switch；The antenna reference it is arranged between the antenna and the main reference ground；It is described
Antenna is connect with the antenna reference ground short circuit, passes through the switch and tuning device and the main reference to the antenna reference
Ground connects；Wherein, the size on the antenna reference ground for antenna institute radiating bands half-wavelength.
It proposes a kind of communication terminal, includes the antenna assembly of communication terminal, the antenna assembly of the communication terminal includes
Signal source and antenna, the signal source connect the antenna；Further include main reference ground, antenna reference and switch；The antenna
Reference ground is arranged between the antenna and the main reference ground；The antenna is connect with the antenna reference ground short circuit, described
It is connect with the main reference ground by the switch and tuning device to antenna reference；Wherein, the size on the antenna reference ground
For the half-wavelength of antenna institute radiating bands.
Compared with prior art, the advantages of the application and good effect is：The day for the communication terminal that the application proposes is traditional thread binding
It sets and communication terminal passes through the increase antenna reference ground between antenna and main reference ground for large scale telecom terminal product
Form solves the problems, such as the invalid excitation to antenna efficiency in the case of large scale reference ground, further by antenna reference with master
Reference ground realizes the change for antenna reference exciting effective dimensions in setting position by the conducting switching of switch, realizes antenna
The raising of efficiency and the multiband covering of antenna, solve the lower technology of antenna launching efficiency of existing large scale communication terminal
Problem.
After the detailed description of the application embodiment is read in conjunction with the figure, other features and advantages of the application will become more
Add clear.
Description of the drawings
Fig. 1 is the antenna assumption diagram of the antenna assembly for the communication terminal that the application proposes；
Fig. 2 is the specific implementation illustration of the antenna assembly for the communication terminal that the application proposes.
Specific implementation mode
The specific implementation mode of the application is described in more detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the antenna assembly for the communication terminal that the application proposes, including signal source 11 and antenna 12, signal source
11 connection antennas 12；Further include main reference ground 13, antenna reference 14 and switch 15；Antenna reference 14 be arranged in 12 He of antenna
Between main reference ground 13；Antenna 12 is connect with 14 ground short circuit of antenna reference, 14 passes through switch 15 and tuning device to antenna reference
16 connect with main reference ground 13；Wherein, the size on antenna reference ground for antenna institute radiating bands half-wavelength.
It is right that form by increasing antenna reference ground between antenna and main reference ground solves large scale reference ground
The invalid excitation problem of antenna efficiency, further by antenna reference being led by switch in setting position with main reference ground
The change for antenna reference exciting effective dimensions is realized in logical switching, realizes the raising of antenna efficiency, solves existing large scale
The relatively low technical problem of the antenna launching efficiency of communication terminal.
Main reference ground 13 can be the metal shell of communication terminal or the reference ground of pcb board.In Fig. 1, with all-metal machine
For the Antenna Design of the U-shaped PAD to crack of shell, main reference ground 11 is the metal shell of PAD, with the U-shaped independence cracked and be separated out
Metal part 14 is set in the projected area of main reference ground 13 to antenna reference as antenna 12, in electrical connection, antenna 12 with
14 connections of antenna reference ground, realized by switch 15 and tuning device 16 between 14 and main reference ground 13 to antenna reference connect or
It disconnects.Here tuning device is capacitance or inductance, is used for the self-impedance of tuned antenna, passes through multiple switch and tuning device
Connection switching, can realize the switching to antenna resonance frequency range, it is existing switching antenna match design basis on can be real
The now switching of more wide-band.
In above-mentioned antenna assembly, antenna 12 can be the design forms such as unipole antenna, PIFA antennas, LOOP antennas, such as
PIFA, LOOP antenna itself needs the position being grounded, then only with antenna reference connect.
Same antenna reference ground can be used for mutiple antennas, and can to mutiple antennas by earthing position into the tune of line frequency
It is humorous.
The application also proposes a kind of communication terminal using said antenna device, below with a specific embodiment to logical
The above-mentioned antenna assembly of letter terminal applies is described in detail.
As shown in Fig. 2, the metal shell main body of PAD, as main reference ground 23, PAD metal shells are isolated only with gap
