Description
Technical field
The utility model belongs to the mobile communication terminal field, mainly is to be applied in the mobile phone products with two built-in aerials.
Background technology
Along with development of technology and the consumer demand to product, two features of mobile communication product seem more and more important in intense market competition, and that is exactly the miniaturization and the multifunction of product.And in littler space, add more function, just our present designing technique is had higher requirement.
In mobile phone products, double-module double-standby has become a spotlight of present mobile phone market.And present high-end mobile phone all is the built-in aerial that adopts, and for example the double-module double-standby of CDMA and GSM and two GSM double-module double-standby product all are that the standby simultaneously of two communication modules is used.Two standby products all are to adopt two cover RF radio-frequency transmissions receiving systems, so also need two antennas naturally.The design of antenna for mobile phone generally adopts Mono Pole unipole antenna or PIFA skin to send out antenna.Because it is overlapping that the frequency range of two antennas has, generally in order to reduce influencing each other of two antennas, present double antenna adopts the two ends that two antennas are placed on mobile phone respectively, and an antenna is placed on the upper end of mobile phone, and another antenna is placed on the lower end of mobile phone.
Prior art is on the dual-mode handset two independently antennas to be arranged, and difference layout two ends about mobile phone, and the problem of Cun Zaiing is exactly that two antennas take mobile phone space greatly like this, is unfavorable for the outward appearance miniaturization of dual-mode handset.How to reduce the space that two antennas occupy and guarantee that the good emission receptivity of antenna is a subject matter to be solved in the utility model in mobile phone.
Summary of the invention
The purpose of this utility model, just be to solve in the dual-mode handset two antennas too big problem that takes up room, the mobile phone of the two built-in aerials of a kind of miniaturization is provided, two antennas have been produced on the same antenna holder, effectively reduced the structure space that antenna occupies.
To achieve the above object, the utility model is achieved by the following technical solutions:
The mobile phone of the two built-in aerials of miniaturization, comprise first antenna element and second antenna element, first antenna element and second antenna element are placed side by side on same antenna holder, and the open end of the open end of first antenna element and second antenna element lays respectively at the both sides of antenna holder.
Another technical characterictic of the technical program is: the spacing between first antenna element and second antenna element is not less than 5mm.
Another technical characterictic of the technical program is: all have at least two frequency ranges on first antenna element and second antenna element, the antenna cabling mode adopts low frequency to surround the parallel cabling mode of high frequency.Low frequency is the EGSM frequency range, and high frequency is the DCS frequency range.Interstice coverage between the parallel cabling of antenna is 1.0-1.3mm.
Another technical characterictic of the technical program is: first antenna element and second antenna element all are Mono Pole unipole antennas.The antenna direction of routing of first antenna element and second antenna element is symmetrical.
Another technical characterictic of the technical program is: the altitude range of two antenna elements is 5-6mm, is preferably 5.5mm.
Compared with prior art, the good effect that the utility model produces be to adopt the form of parallel cabling make two antennas side by side layout on same antenna holder, only take the size of an antenna space, reduced the structure space that antenna takies, also simplified technological process simultaneously.Under the situation that transmits and receives index that guarantees antenna, dwindle antenna to greatest extent and occupied the mobile phone volume inside, adapt to the demand of present communication product miniaturization.
Description of drawings
Fig. 1 is the schematic diagram that a antenna medium and low frequency centers on the high frequency cabling in the utility model;
Fig. 2 is the schematic layout pattern of the two built-in aerials of the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the mode of Mono Pole unipole antenna coupling cabling is adopted in the design of antenna, the advantage of unipole antenna is exactly the environmental condition that can make full use of structure, the design of in the space of minimum, finishing antenna with the shortest cabling area and spatial volume, compare with the Pifa antenna, unipole antenna can reduce to 2/3rds space at least.
In the present embodiment, dual-mode handset has two GSM unipole antennas, on the cabling of unipole antenna, adopt coupled modes, there are two frequency ranges in the antenna 1, low-frequency range 101 is that EGSM frequency range and high band 102 are the DCS frequency range, and wherein the EGSM frequency range is extension GSM, extends 10MHz downwards at GSM900MHz channel medium frequency; The DCS frequency range is 1800MHz, and feedback point 12 is signal feed pin of antenna 1, need be connected on the cell phone mainboard.
The mode that antenna 1 adopts low frequency (EGSM) 101 to surround high frequency (DCS) 102 parallel cablings, similar co-planar waveguide cabling, thereby between low frequency 101 and high frequency 102 cablings, produce strong TE mould electromagnetic field, make antenna 1 energy own all be enclosed in the space of its encirclement like this, and to the device around the antenna become just not so responsive, the influence of active device such as metal around having reduced.Cabling gap each other needs strict control in antenna 1, interval S 1, interval S 2 and interval S 3 all have material impact to the emission receptivity of antenna, it is the principal element of antenna debugging, each spacing size will be decided according to operating frequency and manufacture craft, in the mobile phone product, generally require spacing between the 1.0-1.3mm scope, in the two GSM dual-mode handsets of embodiment, interval S 1, interval S 2 and interval S 3 are selected less than 1.3mm.
As shown in Figure 2, comprise two built-in Mono Pole unipole antennas in the dual-mode handset, antenna 1 and antenna 2, also there are two frequency ranges in antenna 2, be respectively that low-frequency range 201 is that EGSM frequency range and high band 202 are the DCS frequency range, the high band of two antennas and low-frequency range all adopt the mode of Mono Pole unipole antenna coupling cabling to design, and make two mutual electromagnetic effects of antenna reduce, feedback point 22 is signal feed pin of antenna 2, need be connected on the cell phone mainboard.
In antenna 1 and antenna 2,, and taked the cabling form of co-planar waveguide line, optimized the MonoPole magnetic field structure, the influence of active device such as metal around having reduced all with MonoPole form cabling.But still have very big influence between antenna 1 and the antenna 2, so must keep a minimum spacing between antenna 1 and the antenna 2, the size of minimum spacing is relevant with the frequency range height.The minimum range of two two antennas of GSM dual-mode handset is chosen as 5mm in an embodiment.Promptly require between two antennas distance more than or equal to 5mm.
In order further to reduce interacting between two antennas, also to adjust each gap between the antenna according to environment on every side.In order to reduce two couplings between antenna, in the particular hardware circuit, need to debug the size of spacing W1, W2, W3, W4 and W5.The altitude range of two antenna elements is 5-6mm, is preferably 5.5mm.
Use the utility model, the radiation of antenna is little for the influence of surrounding environment, and has reduced by two gross spaces that antenna occupies.
