Abstract
The utility model relates to a mobile terminal antenna, which comprises an antenna conductor and an antenna supporting medium for supporting the antenna conductor. The mobile terminal antenna is characterized in that: at least one discrete component is arranged in the antenna conductor; and the discrete component is used for producing new signal loops in the antenna conductor. Newly produced signal loops can resonate in a desired frequency to cause the antenna to cover multiple frequency ranges by changing values of the discrete components as well as the positions of the discrete components in the antenna conductor. The signal loops are increased by arranging the discrete components, so the mobile terminal antenna has a simple structure and can meet requirement on a miniaturization design of the mobile phone antenna.
Description
Technical field
The utility model relates to the monopole antenna of a kind of antenna, particularly a kind of portable terminal.
Background technology
Radio communication development in recent years is very fast, and many mobile phones become more and more littler, and the shared space of antenna for mobile phone also needs corresponding reducing, and has the flat plane antenna of low section characteristic because volume is less, has been widely used in the antenna for mobile phone design.In addition, for satisfying the needs that antenna for mobile phone covers a plurality of frequency band signals, existing solution is to constitute a plurality of signal circuits the antenna conductor stack with individual signals loop.As the patent No. is that the Chinese utility model patent of ZL200520000478.0 (notification number is 2765337Y) has disclosed a kind of broadband multiloop mobile terminal antenna, metal conductor portion in this patent comprises at least two signal circuits, each signal circuit starts from same common feed point, ends at earth point.By introducing a plurality of signal circuits, make antenna can cover a plurality of frequency ranges, realized multiband resonance.After weak point was introduced a plurality of signal circuits, it is complicated that antenna structure can become, and antenna volume also can correspondingly increase, and the miniaturization Design thinking of this and antenna is disagreed.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned prior art, provide a kind of simple in structure, satisfy miniaturization Design and require and can realize multiband resonating movement terminal antenna.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, common monopole antenna has only a resonant tank, and promptly signal flows along conductor after entering from distributing point 3, flows into earth point 4 and forms a signal circuit, and this antenna only covers a certain frequency range of signal.
Embodiment one: as shown in Figures 2 and 3, this mobile terminal antenna comprises antenna conductor 1, antenna Supporting Media 2 and electric capacity 5, and wherein antenna Supporting Media 2 is used for supporting antenna conductor 1, and antenna conductor 1 is electrically connected with the mainboard 7 of portable terminal.Because electric capacity 5 has high pass characteristic, the low frequency signal in the wireless modulated signals can only flow along original conductor, promptly enters the back from distributing point 3 and flows along conductor, flows into earth point 4 and forms a signal circuit.High-frequency signal then flows in the conductor on opposite by electric capacity 5, flows into earth point 4 at last, has so just formed new signal circuit, make antenna can resonance on new frequency range.Resonance frequency can be adjusted in value and position by control capacittance 5, makes new signal circuit can cover the frequency range that we need.Select the value of suitable electric capacity 5, when signal was GSM900, electric capacity 5 was equivalent to big impedance, and signal is selected the A path, and the A path just in time is four/wavelength, just in time resonance for GSM900.When signal was DCS/PCS, electric capacity 5 was equivalent to short circuit, and signal is selected the B path, and the B path just in time is four/wavelength, just in time resonance for DCS/PCS.Can know by the simulation result of Fig. 6 and to see that this antenna has two resonant tanks.
Embodiment two: as shown in Figure 4, based on embodiment one, increase an electric capacity on antenna conductor 1, electric capacity 52 is connected in parallel with electric capacity 51.In like manner, wireless modulated signals enters along conductor from distributing point 3 and flows, and flows into earth point 4 at last.The value of these two electric capacity of choose reasonable and their positions in antenna conductor 1, can on the basis of two resonant tanks of embodiment one, increase a new resonant tank again, can know by the simulation result of Fig. 7 and to see that at this moment, antenna one has three resonant tanks.
Embodiment three: as shown in Figure 5, based on common monopole antenna, inductance 6 is set in antenna conductor 1, because inductance 6 has low-pass characteristic, high-frequency signal in the wireless modulated signals enters when flowing through inductance 6 and can only reflux along original conductor from distributing point 3, and low frequency signal then flows in the conductor on opposite by inductance 6, flows into earth point 4 at last, form new signal circuit, make antenna can resonance on new frequency range.Can adjust resonance frequency by value and the position of regulating inductance 6, make new signal circuit can cover the frequency range that we need.
