The built-in television antenna for the mobile terminal realizes the built-in mode of a mobile terminal television antenna, is beautiful and practical, is free from the restriction of regions, basically overlays low-medium-high frequency signal reception in the frequency range of between 50MHz to 800MHz, and relatively low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of television antenna, the built-in television antenna of especially a kind of portable terminal.
Background technology
The mobile phone that has TV functions now is more and more universal, television antenna is as the requisite key components of Digital Video Broadcasting Handheld, characteristics such as its radiation efficiency, directivity, bandwidth and impedance matching will produce a very large impact communication products, simultaneously, it can also bring many surcharges to mobile communication product, as miniaturization, light and handy, aesthetic appearance and low radiation etc.At present both at home and abroad the antenna for mobile phone that uses roughly has following several: external fixed, externally can directly stretch formula and built-in.
The external non-scanning antenna of Shi Yonging mainly is outer being connected on the shell of mobile phone in the market, external can directly stretch to stretch out when the formula antenna is to use carry out the reception of TV signal, this antenna operation gets up than fixed trouble, and these two kinds of antennas all adopt two resonance points to design, can not cover completely this scope of 50MHz～800MHz of crossing over VHF and two frequency ranges of UHF, cause the signal reception between 50MHz～200MHz bad.Built-in antenna relative fixed formula and stretch formula antenna profile better appearance, do not see antenna from the outside of machine, but the frequency range of television antenna is very wide, want built-in words must give up many frequencies, this antenna generally is that certain area is customized, and carries out the reception of signal specific according to certain regional signal, and resonance point is debugged in specific frequency range, this antenna is taken other place, and TV receiving effect will be very poor.
FPC is the abbreviation of Flexible Printed Circuit, claim Flexible Printed Circuit, flexible printed circuit board or flex circuit application again, be called for short soft board, be to be a kind of pliable printed circuit that base material is made, have the characteristics of distribution density height, in light weight, thin thickness with height reliability with polyimides or polyester film.
The utility model content
The purpose of this utility model provides a kind of built-in television antenna of portable terminal that adopts the multi resonant technology of shaking to realize, does not have zonal restriction during work, can remedy external antenna frequency band relative narrower, use inconvenient and inaesthetic shortcoming.
The technical scheme that its technical problem that solves the utility model adopts is:
The built-in television antenna of a kind of portable terminal, comprise antenna body, wherein, described antenna body is printed on the battery bonnet inboard of portable terminal with the broken line structure of repeatedly bending, one end of described antenna body is provided with antenna feed point, and described antenna feed point is communicated with the mainboard feedback point of portable terminal by thimble.
The built-in television antenna of above-mentioned portable terminal, wherein, described thimble be shaped as two sections cylindrical stacks that diameter is different, one that diameter is bigger is welded on the portable terminal mainboard.
The built-in television antenna of above-mentioned portable terminal, wherein, the material of described thimble is a brass.
The built-in television antenna of above-mentioned portable terminal, wherein, the material of described thimble is the brass of surface gold-plating.
The built-in television antenna of above-mentioned portable terminal, wherein, described antenna body is the microstrip line material.
The built-in television antenna of above-mentioned portable terminal, wherein, described antenna feed point is a sheet metal.
The built-in television antenna of above-mentioned portable terminal, wherein, described portable terminal is mobile phone or MP4 or PDA or notebook computer.
The beneficial effects of the utility model are embodied in:
1, realized that in limited plane space the mobile terminal television antenna is built-in, does not influence the appearance design of portable terminal;
2, not limited by the region, the low-band signal that can take into account 50MHz～200MHz well receives;
3, compare with existing built-in aerial, cost of manufacture is comparatively cheap.
Description of drawings
Fig. 1 is the structural representation of the built-in mobile TV antenna of the utility model portable terminal;
Fig. 2 is the passive oscillogram of the built-in mobile TV antenna of the utility model portable terminal in 50MHz to 1GHz frequency range.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as qualification of the present utility model.
Please referring to shown in Figure 1, the built-in TV antenna package of the utility model portable terminal is drawn together antenna body 1, antenna body 1 is printed on battery bonnet 3 inboards of portable terminal by the FPC technology with the broken line structure of repeatedly bending, it is made that the battery bonnet 3 of portable terminal is generally plastics, the antenna body 1 more smooth therebetween position of arranging, square wave figure among the graphics class likelihood signal figure after arranging, the benefit of arranging like this is to adjust the length and the width of antenna body when design in limited plane space more easily, the length and the width of antenna body are formulated according to actual needs, are good to reach optimum receiving signal.Antenna body 1 is surperficial microstrip line material, microstrip line thin-film technique manufacturing, and dielectric substrate is selected dielectric constant height, material that lossy microwave is low for use, and the speed of its transmission signals is faster than strip line.One end of antenna body 1 is provided with an antenna feed point 11, and antenna feed point 11 is a sheet metal, is communicated with the mainboard feedback point of portable terminal by thimble 2.Thimble 2 be shaped as two sections cylindrical stacks that diameter is different, on diameter the is bigger feedback point that is welded on the portable terminal mainboard, the other end props up the antenna feed point 11 of battery bonnet 3 inboards.The material of thimble 2 is a brass, and the surface can be gold-plated, can increase the conductivity of thimble 2 after gold-plated, more helps the transmission of high-frequency signal.Portable terminal herein can support to move the equipment of playing TV for ease of the mobile phone that carries or MP4 or PDA or notebook computer etc.
The built-in television antenna of the utility model portable terminal adopts the multi resonant technology of shaking, in the bandwidth range of 50MHz～200MHz, be coupled out the another one resonance point, make this programme that preferable low-frequency effect be arranged, passive oscillogram has solved the shortcoming of low-frequency range received signal difference of present external antenna and the problem that built-in aerial has regional restriction as shown in Figure 2.On the price, the manufacturing materials cost of the utility model product has nearly been economized half than existing external telescopic antenna and built-in aerial price.
In sum, the built-in television antenna of the utility model portable terminal has realized that in limited plane space the mobile terminal television antenna is built-in, and is both artistic and practical, not limited by the region, substantially the low, middle and high frequency rate signal that has covered in 50MHz～800MHz frequency range receives, and cost of manufacture is comparatively cheap.
