Description
Technical field
This practicality relates to wireless communication antenna field, particularly relates to a kind of antenna for mobile phone being applied to 4G communication.
Background technology
Development along with data communication Yu multimedia service demand, the forth generation mobile communication adapting to mobile data, mobile computing and mobile multimedia running needs starts to rise, 4G communication, because its ultra-high data transmissions speed having, is described as " dialogue at a high speed " undisputed between machine by alliance of Internet of Things school-run enterprise of China.But the low frequency of ultra-wideband antenna all can be limited by antenna size, in particular space, the most how to design a great problem that the sufficiently wide antenna of bandwidth is industry.On the other hand, the fast development of modern integrated circuits technology and technique makes electronic product also become more and more less, and wherein antenna is as the end fitting in Wireless Telecom Equipment, and the realization to miniaturization is also extremely urgent.
Utility model content
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide that a kind of size is little, volume is little, the antenna for mobile phone being applied to 4G communication of ultra broadband.
This utility model be the technical scheme is that a kind of antenna for mobile phone being applied to 4G communication, described mobile phone includes antenna and substrate, described antenna is arranged in surface, described antenna includes the couple feed sheet metal being sequentially connected, L-shaped inductance sheet metal and radiation sheet metal, described couple feed sheet metal is parallel with L-shaped inductance sheet metal, described couple feed sheet metal distance metal ground is 1mm, described L-shaped inductance sheet metal includes the first sheet metal and the second sheet metal, described first sheet metal is positioned at substrate center, the connection parallel with couple feed sheet metal of described radiation sheet metal, described radiation sheet metal includes long radiation sheet metal and short radiation sheet metal.
Further, described couple feed metal length of a film 25mm, wide 5mm, it is for carrying out couple feed to whole antenna.
Further, described radiation sheet metal includes long radiation sheet metal and short radiation sheet metal, described its current path length of long radiation sheet metal is 78mm, it mainly produces two resonant modes, respectively near 850MHz and 1900MHz, described short radiation sheet metal its be primarily generated at the resonant mode near 2400MHz, its current path length is about 18mm.
Further, described long radiation sheet metal having a breach, it can be used to regulate resonant mode produced by long radiation sheet metal.
Further, described breach, long 18mm, wide 3mm.
Further, described long radiation sheet metal is by being placed at bending fold on the height supporter for 3mm.
Further, the dielectric constant that above support is is 2.
The beneficial effects of the utility model are: this utility model uses planar monopole antenna, use two primary radiation minor matters simultaneously, so just have two resonant modes at high frequency treatment, so adjust the position of two resonant modes, make its resonant mode near just forming relatively wide frequency band at HFS, it is achieved the miniaturization of antenna, multiband, wideband.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.
As shown in Figure 1, a kind of antenna for mobile phone being applied to 4G communication, described mobile phone includes antenna 1 and substrate 2, described antenna 1 is arranged in above substrate 2, described antenna 1 includes the couple feed sheet metal 3 being sequentially connected, L-shaped inductance sheet metal 4 and radiation sheet metal 5, described couple feed sheet metal 3 is parallel with L-shaped inductance sheet metal 4, described couple feed sheet metal 3 apart from metal for 1mm, described L-shaped inductance sheet metal 4 includes the first sheet metal and the second sheet metal, described first sheet metal is positioned at substrate center, the connection parallel with couple feed sheet metal 4 of described radiation sheet metal 5, described radiation sheet metal includes long radiation sheet metal and short radiation sheet metal.
Operation principle: feed at distributing point, arrange its characteristic impedance be 50 its carry out couple feed by couple feed sheet metal 3 to whole antenna again, the distance on its distance metal ground is 1mm, on the right side of it, a L-shaped inductance sheet metal 4 is introduced on the centrage of whole substrate 2, it is equivalent to inductance short circuit minor matters, not only can play short circuit effect but also can improve the impedance matching of antenna.Use planar monopole antenna, use two primary radiation minor matters simultaneously, so just have two resonant modes at high frequency treatment, so adjust the position of two resonant modes, make its resonant mode near just forming relatively wide frequency band at HFS, it is achieved the miniaturization of antenna, multiband, wideband.
Being further used as preferred embodiment, described couple feed metal length of a film 25mm, wide 5mm, it draws through test of many times for carrying out couple feed to whole antenna, and under word parameter, antenna overall bandwidth is wider.
It is further used as preferred embodiment, described radiation sheet metal 5 includes long radiation sheet metal 6 and short radiation sheet metal 7, described its current path length of long radiation sheet metal 6 is 78mm, it mainly produces two resonant modes, respectively near 850MHz and 1900MHz, described short radiation sheet metal 7 its be primarily generated at the resonant mode near 2400MHz, its current path length is about 18mm.Use two primary radiation minor matters simultaneously, so just have two resonant modes at high frequency treatment, so adjust the position of two resonant modes so that it is resonant mode is near just forming relatively wide frequency band at HFS.Use two primary radiation minor matters simultaneously, so just have two resonant modes at high frequency treatment, so adjust the position of two resonant modes so that it is resonant mode is near just forming relatively wide frequency band at HFS.
Being further used as preferred embodiment, described long radiation sheet metal has a breach, it can be used to regulate resonant mode produced by long radiation sheet metal.
